vue-cli-service Permission denied

环境：ubuntu 18.04 LTS

运行npm run dev，出现如下错误：

searchstar@searchstar-YangTianA8000f-11:~/git/projects/pingshanxyz$ sudo npm run dev
[sudo] password for searchstar:

npm install一下，又出现如下错误：

searchstar@searchstar-YangTianA8000f-11:~/git/projects/pingshanxyz$ npm install

按照提示，输入

sudo chown -R $USER:$(id -gn $USER) /home/searchstar/.config

然后把node_modules丢掉

mv node_modules/ ..

再跑一次

npm install
npm run dev

就成功跑起来了。
