提示：本文展示了vue项目中配置eslint，在vscode编辑器中保存后可以自动修复
本次配置达到的效果：vue代码格式有问题会根据插件的eslint规则红色波浪线提示、ctrl+s保存后根据波浪线的规则进行代码修复（包括自动删除尾部逗号等）
vue项目配置eslint，vscode下载的eslint插件，与npm下载eslint插件有各种冲突，导致如vscode编辑器格式化以后会有一大堆红色波浪线等问题，下面我列出我的相关配置，可以供参考。
vscode安装的插件
vscode的settings.json的相关配置项
1.打开配置文件方法：文件->首选项->设置->输入框输入settings
2.下面是settings.json的配置
以下列出我完整的配置，主要是搜索关键词eslint、editor，若是嫌麻烦，可以备份自己的配置后，直接把这个配置替换
