# NPM - EPERM 錯誤

npm install fails on Windows with "EPERM, operation not permitted" error during rename

npm install 無所不能，npm install  一招抓遍天下。（Ｘ

問題狀況
----

在 npm install 套件時，若出現 EPERM 錯誤，如下圖：

可看到 Error: EPERM:  operration not permitted, rename .....

當初還搞不清以為什麼不支援系統之類的東東哈哈

還一度以為安裝的 [react-native-nav](https://www.npmjs.com/package/react-native-nav) 不支援 windows 等等

處理方式
----

在這邊我們只需要清除快取即可

```bash
npm cache clean
```

之後再重新，安裝套件

就可以看到啦～～～

```bash
npm install
```
