Currently in Azure I am utilizing a 'Azure Website' instance to try and run Docpad (NodeJS App). Within my package.json file I have the following defined..
"engines": {
"node": "0.10.21",
"npm": "1.x"
},
I have tried numerous different entries, from 0.10.x to 0.8.x all listed here => http://azure.microsoft.com/en-us/documentation/articles/nodejs-specify-node-version-azure-apps/
The problem is that Docpad is using Dependencies with Semver Entries and Azure seems to be ignoring my defined Node version entirely, as there are errors such as...
npm WARN engine docpad#6.69.2: wanted: {"node":">=0.8","npm":">=1.2"} (current: {"node":"0.6.20","npm":"1.1.37"})
Because of this, I am getting critical/failure errors when NPM goes to install Docpad due to dependencies such as this...
npm ERR! Error: No compatible version found: rimraf#'^2.2.8'
npm ERR! Valid install targets:
npm ERR! ["1.0.0","1.0.1","1.0.2","1.0.4","1.0.5","1.0.6","1.0.7","1.0.8","1.0.9","2.0.0","2.0.1","2.0.2","2.0.3","2.1.0","2.1.1","2.1.2","2.1.3","2.1.4","2.2.0","2.2.1","2.2.2","2.2.3","2.2.4","2.2.5","2.2.6","2.2.8"]
I have even gone as far as to try printing the Node Version in my deployment script, only to have it return the Environment Variable Azure supposedly honors, but it is clearly invalid.
All I am trying to do is deploy a Docpad website on Azure and I am dumbfounded as to how this is so difficult to to just use a semi-recent version of node in Azure. Any help at all would be greatly appreciated!
node and npm are now npm packages that can be installed as dependencies of your project, so it will run with the correct versions once its dependencies are installed.
However, to install those packages you will need to start with newer versions than the ones you have in your engines section:
Without npm >= 3 installing the node package will break your system by removing the existing version of node too soon
Without node >= 4 the npm package won't work (it isn't specific as to what goes wrong)

I am new to React js, While using npm start after install the react not working,I tried every process but no use. Thanks in advance
Error
cricdost#0.1.0 start C:\xampp\htdocs\cd-web
react-scripts start
There might be a problem with the project dependency tree.
It is likely not a bug in Create React App, but something you need to fix locally.
The react-scripts package provided by Create React App requires a dependency:
"webpack": "4.41.2"
Don't try to install it manually: your package manager does it automatically.
However, a different version of webpack was detected higher up in the tree:
C:\xampp\htdocs\node_modules\webpack (version: 4.39.2)
Manually installing incompatible versions is known to cause hard-to-debug issues.
If you would prefer to ignore this check, add SKIP_PREFLIGHT_CHECK=true to an .env file in your project.
That will permanently disable this message but you might encounter other issues.
To fix the dependency tree, try following the steps below in the exact order:
Delete package-lock.json (not package.json!) and/or yarn.lock in your project folder.
Delete node_modules in your project folder.
Remove "webpack" from dependencies and/or devDependencies in the package.json file in your project folder.
Run npm install or yarn, depending on the package manager you use.
In most cases, this should be enough to fix the problem.
If this has not helped, there are a few other things you can try:
If you used npm, install yarn (http://yarnpkg.com/) and repeat the above steps with it instead.
This may help because npm has known issues with package hoisting which may get resolved in future versions.
Check if C:\xampp\htdocs\node_modules\webpack is outside your project directory.
For example, you might have accidentally installed something in your home folder.
Try running npm ls webpack in your project folder.
This will tell you which other package (apart from the expected react-scripts) installed webpack.
If nothing else helps, add SKIP_PREFLIGHT_CHECK=true to an .env file in your project.
That would permanently disable this preflight check in case you want to proceed anyway.
P.S. We know this message is long but please read the steps above :-) We hope you find them helpful!

I had faced the same error. The solution that I found is to do the step-6 as described in Error message. That is to delete "webpack" folder of node_module folder under your root projects directory. For example
Assume that you installed "npm install create-react-app" in D:\Projects folder.
And then you ran "npx create-react-app firstproject" in D:\Projects folder. So, your actual react project folder is "D:\Projects\firstproject".
So, what I want to tell is don't delete "webpack" folder in "D:\Projects\firstproject\node_module" directory. Instead, delete "webpack" folder in "D:\Projects\node_module" directory.
And then, you can run "npm start" command in your actual react project directory "D:\Projects\firstproject".
I hope, this will work for you.
I've recently upgraded to node8 (using nvm) and a weird things started to happen in one of the project I'm working on.
Node v8.11.1
Npm 5.6.0
I cd inside my project having a packages.json.
For dev purposes I wanted to remove some packages previously installed but I didn't want to modify my packages.json.
Whenever I run either npm uninstall package-name or npm install packages-name they both try to install all the missing packages listed in packages.json!
I am explicitly NOT passing the --save or --save-dev flag but still npm ignores that.
I think it might have to do with package-lock.json file?
Q: How to tell npm I do not want it to mess up with other packages or modify my packages.json?
I have some strange issue regarding the package-lock.json.
We are using npm 5.6 and node 8.9.2.
We have some project with dependencies. The developers can install the deps and push the package-lock.json as recommended:
...
"dependencies": {
"source-map": {
"version": "0.6.1",
"resolved": "https://registry.npmjs.org/source-map/-/source-map-0.6.1.tgz",
"integrity": "sha1-dHIq8y6WFOnCh6jQu95IteLxomM=",
"dev": true
}
}
...
They are getting their dependencies from https://registry.npmjs.org/..
Now we have some jenkins which gets its dependencies from some artifactory which serves as 'proxy' to https://registry.npmjs.org.
The build fails 75% of the times on some error like:
npm ERR! Unexpected end of JSON input while parsing near '...nalInternal" : {
Even when I clean the cache before with sudo npm clean cache --force (or remove .npm)
The error occurs always on a different place.
Now when I remove the package-lock.json before starting the build it works well every time.
A new package-lock.json is generated. It contains not the registry urls but the artifactory urls (https://artifactory/xxx). I thought it could maybe have to do with it. so I replaced the current package-lock.json in git with the one from jenkins. I tried again but again the same error and issue, only deleting the package-lock.json seems to solve it but as I read it's not recommended to ignore this file.
What could be an issue?
So i've been creating a desktop application using electron. The problem is that when I run my application using npm it doesn't show any error about a missing module but when i package it and run it this error shows
I'm sure that i've install mysql module using npm install -g mysql and npm install mysql in the project directory. It's all working fine when i run the unpacked version of the application
Assuming that you have installed mysql if not please install mysql npm install mysql --save-dev
Hi I also ran in same error I tried everything possible but nothing seems to work , after several hit and trial I was able to fix it and in the end realize that it was all happening because of
When I installed MySQL module I never saved it (--save-dev)
And electron-packager was not able to locate it when I pack it because was not mention in package.json
A solution might locate mysql folder in node_module folder and delete
then install it npm install mysql --save-dev
or manually
add it under dependencies in package.json file
I'v made a static single page site using grunt. I'm now trying to deploy it to heroku using the heroku-buildpack-nodejs-grunt for node grunt.
Below is a pic of my root directory:
Here's my Gruntfile package.json:
Procfile:
web: node index.html
When I run $ git push heroku master it gets to the Gruntfile and fails:
-----> Found Gruntfile, running grunt heroku:production task
>> Local Npm module "grunt-contrib-uglify" not found. Is it installed?
The above errors proceed to list all local NPM modules as not found. If I list all loadNpmTasks instead of using "load-grunt-tasks", I get the exact same error.
When I $ heroku logs I get:
Starting process with command `node web.js`
Error: Cannot find module '/app/web.js'
Can anyone see where I've gone wrong?
For anyone passing by here, I wasn't able to solve the problem. This is where I got to:
In my Gruntfile, I moved npm modules from devDependencies to dependencies. Heroku was then able to install these dependencies.
However, when Heroku ran the tasks, it stops at the haml task w/ error "You need to have Ruby and Haml installed and in your PATH for this task to work". Adding ruby & haml to the Gruntfile as engines did not work.
The only thing I can think of is that maybe Heroku installs your devDependencies first, tries to run Grunt, but since it didn't install load-grunt-tasks yet, you don't get the grunt.loadNpmTasks( 'grunt-contrib-uglify' ); line (which load-grunt-tasks does for you), and thus Grunt can't find the package.
Can you try changing your Gruntfile to explicitly list out all npm modules using the grunt.loadNpmTasks() method?
EDIT:
Just remembered another thing I had to do:
heroku labs:enable user-env-compile -a myapp
heroku config:set NODE_ENV=production
(Obviously replacing myapp with your Heroku app name.)
This makes Heroku allow user set environment variables and then sets your server to production. Try that, and set your dependencies and devDependencies as you had them originally (just to see if it works).
I am coming pretty late to the game here but I have used a couple methods and thought I would share.
Option 1: Get Heroku to Build
This is not my favorite method because it can take a long time but here it is anyway.
Heroku runs npm install --production when it receives your pushed changes. This only installs the production dependencies.
You don't have to change your environment variables to install your dev dependencies. npm install has a --dev switch to allow you to do that.
npm install --dev
Heroku provides an article on how you can customize your build. Essentially, you can run the above command as a postinstall script in your package.json.
"scripts": {
"start": "node index.js",
"postinstall": "npm install --dev && grunt build"
}
I think this is cleaner than putting dev dependencies in my production section or changing the environment variables back and forth to get my dependencies to build.
Also, I don't use a Procfile. Heroku can run your application by calling npm start (at least it can now almost two years after the OP). So as long as you provide that script (as seen above) Heroku should be able to start your app.
As far as your ruby dependency, I haven't attempted to install a ruby gem in my node apps on Heroku but this SO answer suggests that you use multi buildpack.
Option 2: Deploy Your Dependencies
Some argue that having Heroku build your application is bad form. They suggest that you should push up all of your dependencies. If you are like me and hate the idea of checking in your node_modules directory then you could create a new branch where you force add the node_modules directory and then deploy that branch. In git this looks like:
git checkout -b deploy
git add -f node_modules/
git commit -m "heroku deploy"
git push heroku --force deploy:master
git checkout master
git branch -D deploy
You could obviously make this into a script so that you don't have to type that every time.
Option 3: Do It All Yourself
This is my new favorite way to deploy. Heroku has added support for slug deploys. The previous link is a good read and I highly recommend it. I do this in my automated build from Travis-CI. I have some custom scripts to tar my app and push the slug to Heroku and its fast.
I faced a similar problem with Heroku not installing all of my dependencies, while I had no issue locally. I fixed it by running
heroku config:set USE_NPM_INSTALL=true
into the path, where I deployed my project from. This instructs Heroku to install your dependencies using npm install instead of npm ci, which is the default! From Heroku dev center:
"Heroku uses the lockfiles, either the package-lock.json or yarn.lock, to install the expected dependency tree, so be sure to check those files into git to ensure the same dependency versions across environments. If you are using npm, Heroku will use npm ci to set up the build environment."
