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。
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
