篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了npm install 报错（npm ERR! errno -4048，Error: EPERM: operation not permitted,）解决方法相关的知识，希望对你有一定的参考价值。

之前有时报这个，以为还真是权限不够，感觉有点奇怪，用管理员权限执行，有时还真有用，不过后面查了下，时缓存的问题，清理下缓存就行，不用管理员权限。

方法1、

需要删除npmrc文件。

强调：不是nodejs安装目录npm模块下的那个npmrc文件

而是在C:\\Users\\账户\\下的.npmrc文件..

方法2、

或者直接用命令清理就行，控制台输入：

npm cache clean --force

added 114 packages in 42.369s
E:\\SouthernPowerGridProject\\web_project\\AutoOPS\\autoops>npm cache clean --force
npm WARN using --force I sure hope you know what you are doing.

E:\\SouthernPowerGridProject\\web_project\\AutoOPS\\autoops>npm install

成功了

Ran reactive-native init in command prompt as Administrator (on Windows OS), hoping works well with sudo reactive-native init on Mac OS
Ran npm cache clean command in Command prompt.
Disable your antivirus for time being.
