AWS ubuntu服务器node.js安装的设置bash脚本失败

Question

I'm trying to write a node.js/MEAN.JS setup bash script based on a script to create a custom node.js development environment on a AWS Ubuntu server.

Well so far so good, but when I tried to start and generalize the script (adding MEAN installation to it) the tests start to fail. It looks like it doesn't install any of the node programs:

    Testing Basic dependencies:
    git                           OK
    gcc                           OK
    g++                           OK
    autoconf                      OK
    automake                      OK
    libtool                       OK
    python                        OK
    make                          OK

    Testing Basic command line editor installations:
    rlwrap                        OK
    emacs                         OK
    nano                          OK

    Testing Node.JS installations:
    node                          missing
    nvm                           missing
    npm                           missing
    heroku                        OK
    foreman                       OK

    Testing MEAN JS Stack installations:
    mongo                         OK
    mongod                        OK
    mean                          missing
    bower                         missing
    grunt                         missing

Also when I try to execute for example node , I get the following error:

    $ node
    The program 'node' can be found in the following packages:
     * node
     * nodejs
    Try: sudo apt-get install <selected package>

The weird thing is when the bash script is executed it seems to be installing everything fine. I've been looking around and can't find why this is happening and what the solution should be? Can it have anything to do with the $PATH ?

I posted the links because the code is quite big. Also, I made it all opensource so if you want to contribute to it, it's fine by me.

Edit 1:

The nvm show that's it's installed:

    [ubuntu@domU-12-31-39-0A-28-86:~]$nvm

    Node Version Manager

    Usage:

    (...)

But when executing test it still shows as missing. node npm mean bower and grunt continue to stay missing and unexecutable.

Edit 2: Added Source code after Louis's comment, Thanks for the insight!

Answer 1

I found what was causing the problem, in one or two cases it had to do with the fact I forgot add sudo , but not most of it.

The problem was that nvm doesn't actually fully install node.js, npm etc. So I had to do those installations via the apt-get install node like this:

# Installing last node and npm version
sudo apt-add-repository -y ppa:chris-lea/node.js
sudo apt-get update
sudo apt-get install -y nodejs

And the other installations should be done after this with the `sudo npm install [package] command.

The code ends up looking like this:
