2 错误详解

该错误发生在修改npm的全局安装路径之后,再执行npm install 包 -g或是npm install 包时发生,但是在管理员身份下运行cmd,均能执行成功。

2.1 修改npm全局安装:
  1. 命令行:
bash 复制代码
npm config set prefix "D:\NodeJS\node_global"
npm config set cache "D:\NodeJS\node_cache"

在C盘User/用户名/下有一个.npmrc的文件

将上述node_global文件夹的路径加入环境变量
2 .2 导致该安装问题的原因

没有管理员权限,无法在node_global和node_cache两个文件夹下进行一些必要的操作
3.

2.3修复方法

  1. 删除用户下的.npmrc文件,即不改变全局安装的路径(不够好,本质问题仍没有解决,全局还是会安装在C盘)

    每次都用管理员身份运行命令行(不够方便,vscode 下的命令行默认也不是管理员身份运行的)

    直接修改node_global和node_cache文件夹的权限:

    右键文件夹,打开属性,切换到安全选项卡

    选择编辑,将没有打钩的位置全部打上钩(即将其它用户的权限设置为与管理员相同),应用即可。

    3 运行测试

    安装webpack测试,成功!

    npm i webpack webpack-cli -g

    npm i webpack webpack-cli --save-dev
