AWS ubuntu服务器node.js安装的设置bash脚本失败

Question

我试图基于脚本编写一个node.js / MEAN.JS安装bash脚本，以在AWS Ubuntu服务器上创建自定义node.js开发环境。

到目前为止，一切都很好，但是当我尝试启动并推广脚本（向其中添加MEAN安装）时，测试开始失败。 看起来它没有安装任何节点程序：

    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

另外，当我尝试执行例如node ，也会出现以下错误：

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

奇怪的是，当执行bash脚本时，似乎一切正常。 我一直在环顾四周，找不到为什么会发生这种情况以及应该怎么解决？ 它与$PATH有什么关系吗？

我发布了链接，因为代码很大。 另外，我将其全部开源，因此，如果您想为它贡献力量，那对我来说很好。

编辑1：

nvm显示已安装：

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

    Node Version Manager

    Usage:

    (...)

但是执行测试时，仍然显示为丢失。 node npm mean bower and grunt继续丢失并且无法执行。

编辑2：在Louis的评论后添加了源代码，感谢您的见解！

我发现了导致问题的原因，在一两个案例中，这与我忘记添加sudo的事实有关，但并不是其中的大多数。

问题是nvm实际上并未完全安装node.js，npm等。因此，我必须通过apt-get install node以下apt-get install node ：

# 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

之后，其他安装应使用sudo npm install [package]命令完成。

代码最终看起来像这样：
