$ npm init
This utility will walk you through creating a package.json file.
It only covers the most common items, and tries to guess sane defaults.
See npm help json for definitive documentation on these fields
and exactly what they do.
Use npm install <pkg> --save afterwards to install a package and
save it as a dependency in the package.json file.
Press ^C at any time to quit.

Answer 1

First initialize your project. Assuming your project lives in directory "sample" then:
cd sample
npm init // This will ask a bunch of questions. you can mostly just hit "enter". it will create the package.json file for you
npm i express --save

Answer 2

using npm init you can create package.json

Answer 3

To clarify a bit on the previous answers, npm install <package-name> and npm install <package-name> --save may fail if you try to run them from a directory that does not have an npm package.json file.
You might type something like npm install crud --save and get some confusing output like this:
npm install crud
npm WARN saveError ENOENT: no such file or directory, open '/Users/youruser/package.json'
npm WARN enoent ENOENT: no such file or directory, open '/Users/youruser/package.json'
npm WARN youruser No description
npm WARN youruser No repository field.
npm WARN youruser No README data
npm WARN youruser No license field.
+ crud#0.0.28
That's not a very helpful error message -- the level is only "warn", and that last line makes it appear that the requested package got installed somewhere. But if you look in your directory, you will see it remains empty. The explanation of this "riddle" is that some package installers (like PHP's composer) will initialize a project and download the package, others (like Python's pip or npm) do not, so you have to initialize the directory and install packages separately.
Run npm init and answer some basic questions about your project, or copy a viable package.json file that follows the format below:
{
"name": "my-great-node-project",
"version": "1.0.0",
"description": "",
"main": "index.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1"
},
"author": "",
"license": "ISC",
"dependencies": {
}
}
Be careful with the package name! The name cannot match the name of a package you trying to install.
Once the directory has been initialize, you should be able to run your npm install <package-name> --save command and have the package installed into the node_modules directory and have your package.json file updated.

Answer 4

Try not to make any space between words in your project folder name. For instance, instead of "My Portfolio" write it like "MyPortfolio". This worked for me and created json file automatically in my project folder.
