AWS ubuntu服務器node.js安裝的設置bash腳本失敗

Question

我試圖基於腳本編寫一個node.js / MEAN.JS安裝bash腳本，以在AWS Ubuntu服務器上創建自定義node.js開發環境。

到目前為止，一切都很好，但是當我嘗試啟動並推廣腳本（向其中添加MEAN安裝）時，測試開始失敗。 看起來它沒有安裝任何節點程序：

    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，當我嘗試執行例如node ，也會出現以下錯誤：

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

奇怪的是，當執行bash腳本時，似乎一切正常。 我一直在環顧四周，找不到為什么會發生這種情況以及應該怎么解決？ 它與$PATH有什么關系嗎？

編輯1：

nvm顯示已安裝：

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

    Node Version Manager

    Usage:

    (...)

但是執行測試時，仍然顯示為丟失。 node npm mean bower and grunt繼續丟失並且無法執行。

編輯2：在Louis的評論后添加了源代碼，感謝您的見解！

我發現了導致問題的原因，在一兩個案例中，這與我忘記添加sudo的事實有關，但並不是其中的大多數。

問題是nvm實際上並未完全安裝node.js，npm等。因此，我必須通過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，其他安裝應使用sudo npm install [package]命令完成。

代碼最終看起來像這樣：
