安装
npm install --save-dev electron
是网络的原因，修改NPM配置
npm config edit
在弹出的配置文件中修改
registry=https://registry.npmmirror.com electron_mirror=https://cdn.npmmirror.com/binaries/electron/ electron_builder_binaries_mirror=https://npmmirror.com/mirrors/electron-builder-binaries/
保存退出后
npm cache clean --force
重新安装
npm install --save-dev electron
成功
