我尝试根据脚本编写node.js / MEAN.JS设置bash脚本，以在AWS Ubuntu服务器上创建自定义node.js开发环境。
到目前为止一切顺利，但是当我尝试启动并概括脚本（向其添加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
当我尝试执行例如node时，我收到以下错误：
$ 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，它似乎正在安装一切。我一直在四处寻找，无法找到原因，解决方案应该是什么？它可以与$PATH？

我发布了链接，因为代码非常大。另外，我把它全部打开了，所以如果你想为它做贡献，那对我来说很好。
P.S。管理员和版主：如果我在问题帖子中出错了，请不要杀我，这是我的第一个，请通知我，我会立即编辑。
编辑1：
nvm显示它已安装：
[ubuntu@domU-12-31-39-0A-28-86:~]$nvm
Node Version Manager
Usage:
(...)
但是在执行测试时，它仍显示为缺失。 node npm mean bower and grunt继续失踪并且无法执行。
编辑2：在路易斯的评论之后添加了源代码，感谢您的见解！
答案 0 :(得分：1)
我找到了导致问题的原因，在一两个案例中，它与我忘记添加sudo的事实有关，但不是大部分。
问题是nvm实际上并没有完全安装node.js，npm等。所以我必须通过apt-get install node这样安装：
# 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
其他安装应在此之后使用`sudo npm install [package]命令完成。
代码最终看起来像这样：
