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：
- 命令行：
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
2.3 修复方法
- 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。
- 右键文件夹，打开属性，切换到安全选项卡
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
