1. 在.eslintrc.js 添加 vscode 终端启动服务
// 添加⾃定义规则
'prettier/prettier': [
// eslint校验不成功后，error或2则报错，warn或1则警告，off或0则⽆提示
'error',
{
singleQuote: true,
semi: false, //结束是否加分号
printWidth: 160//每行最长字符
}
]
2.打开VS code 文件》首选项》设置》扩展》ESLint》
// eslint格式化字符串
"editor.codeActionsOnSave": {
"source.fixAll.eslint": true
},
如果编译 发现以下错误
warning delete ·· (prettier/prettier) “error Delete ⏎ prettier/prettier” in .vue files
解决
在vuejs项目中，运行如下命令解决：
npm run lint – --fix
如果还是没行，就要在 vue.config.js 添加
// vue.config.js
// 旧 data: @import "~@/assets/scss/variables.scss"; // 新 prependData: @import ~@/assets/scss/variables.scss;
module.exports = {
chainWebpack: config => {
config.module
.rule('eslint')
.use('eslint-loader')
.loader('eslint-loader')
.tap(options => {
options.fix = true
return options
})
}
}
