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

 npm run dev 项目，提示

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

根据提示删除electron包，重新安装一次，还是提示错误

单独安装electron

npm install electron -g

提示 http://npm.taobao.org/mirrors/electron/v8.0.3/electron-v8.0.3-win32-x64.zip 无法访问

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

去淘宝electron镜像，找到window 64位的electron，对应的地址是https://cdn.npm.taobao.org/dist/electron/7.1.14/electron-v7.1.14-win32-x64.zip

 所以原因是地址问题，导致上面的错误

官方也给出原因：淘宝镜像的问题

 同时官方给出的解决方法

例如，使用中国镜像：

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

设置electron 镜像源地址：

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

参考：

Electron failed to install correctly, please delete node_modules/electron and try installing again #20994
