1. 在.eslintrc.js 添加 vscode 終端啟動服務

// 添加⾃定義規則 ’prettier/prettier’: [ // eslint校驗不成功后，error或2則報錯，warn或1則警告，off或0則⽆提示 ’error’, { singleQuote: true, semi: false, //結束是否加分號 printWidth: 160//每行最長字符 } ]

2.打開VS code 文件》首選項》設置》擴展》ESLint》

// eslint格式化字符串 'editor.codeActionsOnSave': { 'source.fixAll.eslint': true },

如果編譯 發現以下錯誤

warning delete ·· (prettier/prettier) “error Delete ⏎ prettier/prettier” in .vue files

解決

在vuejs項目中，運行如下命令解決：

npm run lint ? --fix

如果還是沒行，就要在 vue.config.js 添加

// vue.config.js

// 舊 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 }) }}
