What is missing from my PeP proxy installation? - fiware

I am following this tutorial to install PeP proxy.
I have installed both node and npm on my CentOS 6.7:
[root#centos fi-ware-pep-proxy]# node -v
v0.10.41
[root#centos fi-ware-pep-proxy]# npm -v
1.4.29
But when I get into the fi-ware-pep-proxy folder and and run npm install, I get the following error:
[root#centos fi-ware-pep-proxy]# npm install
npm WARN deprecated This version of npm lacks support for important features,
npm WARN deprecated such as scoped packages, offered by the primary npm
npm WARN deprecated registry. Consider upgrading to at least npm#2, if not the
npm WARN deprecated latest stable version. To upgrade to npm#2, run:
npm WARN deprecated
npm WARN deprecated npm -g install npm#latest-2
npm WARN deprecated
npm WARN deprecated To upgrade to the latest stable version, run:
npm WARN deprecated
npm WARN deprecated npm -g install npm#latest
npm WARN deprecated
npm WARN deprecated (Depending on how Node.js was installed on your system, you
npm WARN deprecated may need to prefix the preceding commands with `sudo`, or if
npm WARN deprecated on Windows, run them from an Administrator prompt.)
npm WARN deprecated
npm WARN deprecated If you're running the version of npm bundled with
npm WARN deprecated Node.js 0.10 LTS, be aware that the next version of 0.10 LTS
npm WARN deprecated will be bundled with a version of npm#2, which has some small
npm WARN deprecated backwards-incompatible changes made to `npm run-script` and
npm WARN deprecated semver behavior.

I tried looking for expat-devel which I also yum installed, but the error remains the same.
I also checked my python version and saw that it is:
[root#centos fi-ware-pep-proxy]# python -V
Python 2.6.6
Does anyone have a clue how I can solve this issue?

Thanks to #Álvaro Alonso I came to the conclusion that I should install gcc:
sudo yum install gcc gcc-c++
as explained here:

Thank you!

Have you installed Gulp on your machine yet?
If your folder has a package.json file, make sure you can see Gulp in there listed between your devDependencies. These dependencies are what you use during development of your Node project.
If you don't have a package.json file, you can create one in the command line via npm init, then install Gulp locally on your machine with npm install -g gulp, and then install the command line interface for gulp in your project folder: npm install --save-dev gulp-cli. The CLI will run the Gulp executable with the Gulpfile.js that's in your project.
More information can be found on their website: http://gulpjs.com/

while during npm install with heapdump faciing below error

while install heapdump using nodejs I am facing below error message. I have installed python on the system also. I have to install heapdump package in node_module.
Below is the part of package.json where i have specified the heapdump version.
"grunt-shell": "^0.6.4",
"heapdump": "^0.3.4"

t
You have not specified the operating system in your question but the error trace shows Windows_NT 6.1.7601.
There may be more than one reason for its failure.
node-gyp is a cross-platform command-line tool written in Node.js for compiling native addon modules for Node.js. So when you try to install heapdump, internally it uses 'node-gyp' to rebuild the module for your particular platform (windows/unix/mac etc).
One possible reason is the version of python used. Python v2.7 recommended, v3.x.x is not supported. If this is the case you will get the error like the below.
gyp ERR! configure error
gyp ERR! stack Error: Python executable "python" is v3.5.1, which is not supported by gyp.
gyp ERR! stack You can pass the --python switch to point to Python >= v2.5.0 & < 3.0.0.
To solve this issue you can use the npm install python switch as below.
npm install --python=python2.7
Other reason for failure is specific to OS. If you are installing this on Windows you should have Microsoft Visual Studio C++ 2013 (XP/7/8 etc) or Visual Studio Community 2015 Edition(Windows 10).
Read this link to understand more
I have had a same problem when installing heapdump#^0.3.12 package, npm used node gyb to rebuild package. I changed python version , installed visual bla bla.... but it didn't worked. Then I used another device with another npm and node version, it worked.
I think cause of the problem is node and npm version. I upgraded them then it worked in my device.
Before: node: 10.15.3 After: node: 14.16.1
npm: 6.9.2 npm: 6.14.12
There is a recommendation here. Latest version maybe can't help you, let try with some near version.

npm cache clean
and see if that makes any difference.

npm package build failing, how best to debug?

I'm trying to install a mysql node package on Mac OS X. I'm trying to run a client project locally.
I have node and npm installed already and they work fine, other packages have installed fine. I've also compiled/installed the full LAMP stack.
When the build below fails, I'm not seeing any error messages that are helpful - just information about a library not being found. Without knowing what it can't find, I can't fix it.
Any advice? MySQL has been installed the standard way - downloaded packages, ./configure'd, make/install.

Look at the dependencies section in README and issues #107. To build mysql-libmysqlclient you should install both libmysqlclient and development headers for it, add path to your MySQL bin dir to $PATH and path to your MySQL lib dir to $DYLD_LIBRARY_PATH.
