node.js - 使用 npm 在 Mac OS X 上安装 MEANIO 时出现问题

Question

当我尝试使用 npm 在 Mac 上安装 MEANIO 时，遇到了几个错误，导致安装失败。错误如下所示:

问题主要有两种类型:一种是Error EACCES，另一种是ERROR ENOENT。我尝试了几种解决方案，但并没有多大帮助。

1. sudo npm clear cache 
2. sudo npm update -g
3. Permission fix: by changing nodejs folder's permission to local user 

(引用:npm install errors with Error: ENOENT, chmod)

我想知道是什么原因导致了这个问题。由于我没有发布自己的应用程序，因此无法根据链接中提供的解决方案包含 .npmignore。链接中的第二个答案声称问题的本质是:

"Above action caused some dependencies being installed inside ~/.npm/ dir, having root:root ownership (because of sudo ...). Evidently npm does not run as local user (or change dependencies subdirs ownership afterwards) when pulling dependencies and writing them to a local user subdir ~/.npm/. As long as npm would be so careless against fundamental unix filesystem security issues the problem would reoccur."

我怀疑这对我来说是否正确。 MEANIO 的安装不应该引起这么多问题。

shell 命令和错误消息如下所示:

localhost:local Nick_Guan$ sudo npm install -g meanio@latest

仔细检查先决条件是否安装正确，确保在主目录下的某个位置执行安装命令。

You're in a directory which can be read and searched only by root, and you're su'ing to another user. That user does not have permission to search the current directory, even to find `..', so getcwd is going to fail.
