无法在Mac OS X上npm安装'mean-cli'模块 [英] Cannot npm install 'mean-cli' module on Mac OS X

问题描述

更新: 显然，使用sudo安装节点模块是一种不好的做法.相反，更改文件夹权限将解决此问题.

UPDATE: Apparently, it is bad practice to use sudo to install node modules. Instead, changing folder permissions will solve this issue.

原始帖子:

当前，我已经安装了Node(版本v0.12.7)和NPM.我正在尝试从NPM安装mean-cli软件包.

Currently, I have installed Node (version v0.12.7) and NPM. I am trying to install the mean-cli package from NPM.

我正在按照此处的安装说明进行操作: https://github.com/linnovate/mean#安装

I am following the installation instructions found here: https://github.com/linnovate/mean#installation

此外，我正在参加有关Udemy的MEAN Stack开发课程.这是讲座: https://www.udemy.com/mean-stack- for-beginners/#/lecture/2697540

Also, I was taking a MEAN Stack development course on Udemy. Here is the lecture: https://www.udemy.com/mean-stack-for-beginners/#/lecture/2697540

到目前为止，我已经安装了两个必备软件包Gulp和Bower:

So far, I have installed both prerequisite packages, Gulp and Bower:

$ npm install -g gulp
// and bower
$ npm install -g bower 

首先，我尝试使用npm install -g mean-cli进行安装，但是这引发了权限错误，而没有使用sudo.然后，即使使用sudo也不起作用.

Firstly, I tried installing by using npm install -g mean-cli but that threw permission errors without using sudo. Then, even using sudo would not work.

其次，我尝试更新并重新安装节点和NPM.仍然有同样的问题.

Secondly, I tried updating and reinstalling node and NPM. Still have the same issue.

当我键入命令sudo npm install -g mean-cli时，

我收到以下答复:

> mean-cli@0.10.14 preinstall /usr/local/lib/node_modules/mean-cli
> node ./scripts/preinstall

问题似乎出在这里:Failed at the mean-cli@0.10.14 preinstall script 'node，但是我不确定如何进一步调试它.

It seems like the problem lies here: Failed at the mean-cli@0.10.14 preinstall script 'node, but I am not sure about how to debug this further.

任何见解或有用的信息将不胜感激！谢谢！

Any insight or helpful information is appreciated! Thanks!
