当尝试全局安装包时遇到权限错误，可通过两种方法解决。一是使用节点版本管理器重新安装npm，这能避免权限问题，无需提前移除当前版本；二是手动更改npm默认目录，可配置npm使用不同目录，还给出了具体操作步骤。

If you see an EACCES error when you try to install a package globally, you can either:

Reinstall npm with a node version manager (recommended),

Manually change npm’s default directory

Reinstall npm with a node version manager§

This is the best way to avoid permissions issues. To reinstall npm with a node version manager, follow the steps in “Downloading and installing Node.js and npm”. You do not need to remove your current version of npm or Node.js before installing a node version manager.

Manually change npm’s default directory§

Note: This section does not apply to Microsoft Windows.

To minimize the chance of permissions errors, you can configure npm to use a different directory. In this example, you will create and use hidden directory in your home directory.

Back up your computer.
On the command line, in your home directory, create a directory for global installations:
```
 mkdir ~/.npm-global
```
Configure npm to use the new directory path:
```
 npm config set prefix '~/.npm-global'
```
In your preferred text editor, open or create a ~/.profile file and add this line:
```
 export PATH=~/.npm-global/bin:$PATH
```
On the command line, update your system variables:
```
 source ~/.profile
```
To test your new configuration, install a package globally without using sudo:
```
 npm install -g jshint
```

Instead of steps 2-4, you can use the corresponding ENV variable (e.g. if you don’t want to modify ~/.profile):

NPM_CONFIG_PREFIX=~/.npm-global

# 第一步：在你的用户文件下新建一个文件夹，这个.npm-global 名字可以用你自己喜欢的名字替换，推荐直接使用这个名字。
mkdir ~/.npm-global
#第二步：更改node的安装连接
npm config set prefix '~/.npm-global'
#第三步：在用户的profile下增加path，为的是系统能够找到可执行文件的目录
 export PATH=~/.npm-global/bin:$PATH
#第四步：update profile。使其生效
source ~/.profile
