npm run dev啟動項目，electron提示throw new Error('Electron failed to install correctly, please delete node_modules/electron and try installing again')

 npm run dev 項目，提示

throw new Error('Electron failed to install correctly, please delete node_modules/electron and try installing again')

根據提示刪除electron包，重新安裝一次，還是提示錯誤

 

單獨安裝electron

npm install electron -g

C:\Users\pxm\AppData\Roaming\npm\electron -> C:\Users\pxm\AppData\Roaming\npm\node_modules\electron\cli.js

> core-js@3.6.4 postinstall C:\Users\pxm\AppData\Roaming\npm\node_modules\electron\node_modules\core-js
> node -e "try{require('./postinstall')}catch(e){}"

提示 http://npm.taobao.org/mirrors/electron/v8.0.3/electron-v8.0.3-win32-x64.zip 無法訪問

項目用到的electron 版本v7.1.14，試了 https://npm.taobao.org/mirrors/electron/v7.1.14/electron-v7.1.14-win32-x64.zip 也不行

去淘寶electron鏡像，找到window 64位的electron，對應的地址是https://cdn.npm.taobao.org/dist/electron/7.1.14/electron-v7.1.14-win32-x64.zip

 

 所以原因是地址問題，導致上面的錯誤

 

官方也給出原因：淘寶鏡像的問題

 

 

 同時官方給出的解決方法

例如，使用中國鏡像：

ELECTRON_MIRROR="https://cdn.npm.taobao.org/dist/electron/"

 

設置electron 鏡像源地址：

npm config set electron_mirror https://cdn.npm.taobao.org/dist/electron/
