vscode配置eslint

需要下载的插件

ESLint Prettier - Code formatter

如果用vue-cli生成项目，把ESLint 相关的选上
如果没选上在根目录下新建.eslintrc.js，.gitignore
需要安装的插件

yarn add @vue/cli-plugin-babel @vue/cli-plugin-eslint @vue/eslint-config-prettier babel-eslint eslint eslint-plugin-prettier eslint-plugin-vue prettier

.eslintrc.js，.gitignore 文件在这里：https://www.jianshu.com/p/389fe2309514

保存后可自动格式化
如果设置了没效果，可能是当前窗口打开了多个项目，当前窗口只打开当前配置了eslint的项目才有效
如果项目在vue-element下面的element-pro里，打开的时候是打开element-pro而不是vue-element
