Windows中yarn执行安装(更新)操作时间太久(卡死)

编辑c盘中用户文件夹下的.yarnrc文件

registry "https://registry.npm.taobao.org"
electron_mirror "https://npm.taobao.org/mirrors/electron/"
# 如果存在则不复制这一段

在工程项目文件夹下创建.yarnrc文件

registry "https://registry.npm.taobao.org"

sass_binary_site "https://npm.taobao.org/mirrors/node-sass/"
phantomjs_cdnurl "http://cnpmjs.org/downloads"
electron_mirror "https://npm.taobao.org/mirrors/electron/"
