之前windows打开的项目，用mac打开的时候报错：网上找了解决方案，为了方便查询，再记录一下子
: /Users/dongjingya/Documents/workspace/vue-manage-system/node_modules/.bin/vue-cli-service: Permission denied
npm ERR! code ELIFECYCLE
npm ERR! errno 126
npm ERR! vue-manage-system@4.2.0 serve: `vue-cli-service serve`
npm ERR! Exit status 126
npm ERR!
npm ERR! Failed at the vue-manage-system@4.2.0 serve script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.
解决方案，亲自试了，好用
打开mac终端，输入chmod 777 /Users/此处是项目根目录/node_modules/.bin/vue-cli-service 执行即可。
