问题描述
下载 electron 时，卡在了下载超时，换 github.com ip 无效、用梯子无效，直到官网这里找到了原因：
Mirror
You can use environment variables to override the base URL, the path at which to look for Electron binaries, and the binary filename. The URL used by @electron/get is composed as follows:
url = ELECTRON_MIRROR + ELECTRON_CUSTOM_DIR + '/' + ELECTRON_CUSTOM_FILENAME

For instance, to use the China CDN mirror:
ELECTRON_MIRROR="https://cdn.npm.taobao.org/dist/electron/"

解决办法
1、找国内镜像，比如npmmirror 中国镜像站：
electron 镜像: https://npmmirror.com/mirrors/electron/

2、设置：
# yarn
yarn config set electron_mirror https://npmmirror.com/mirrors/electron/
# npm
npm config set ELECTRON_MIRROR https://npmmirror.com/mirrors/electron/
