mac 下载最新hbuilderx 使用vue-cli创建项目，添加uni-ui，使用，运行到微信小程序，报错

同一套代码，mac下 webstorm 运行 npm run dev:mp-weixin 正常
在win10的 hbuilderx中运行正常

mac解决办法：

cd /Applications/HBuilderX.app/Contents/HBuilderX/plugins/node  mv node node-v8  ln -s /usr/local/bin/node /Applications/HBuilderX.app/Contents/HBuilderX/plugins/node/node
