新手怎么解决 NPM run dev 报错的问题？

新建好项目后，我们切换到项目目录并启动本地服务：

 > cd vuejs-essentia
 > npm run dev

结果报错：

vagrant@homestead:~/Code/vuejs-essential$ npm run dev

> vuejs-essential@1.0.0 dev /home/vagrant/Code/vuejs-essential
> webpack-dev-server --inline --progress --config build/webpack.dev.conf.js

尝试1：
rm -rf node_modules
在运行 npm install
结果报错：

npm WARN ajv-keywords@3.2.0 requires a peer of ajv@^6.0.0 but none is installed. You must install peer dependencies yourself.

尝试2：
rm -rf node_modules
在运行 yarn install --no-bin-links

vagrant@homestead:~/Code/vuejs-essential$ rm -rf node_modules/
vagrant@homestead:~/Code/vuejs-essential$ yarn install --no-bin-links
yarn install v1.7.0
