Eslint 解析器的误报

Question

我在运行连接 vue 应用程序时收到误报错误。它告诉构造函数名称不应该以小写字母开头。如何解决这个问题。

我的.eslintrc.js如下

module.exports = {
  root: true,
  env: {
    browser: true,
    node: true,
  },
  parserOptions: {
    parser: 'babel-eslint',
  },
  extends: [
    '@nuxtjs',
    'prettier',
    'prettier/vue',
    'plugin:vue-scoped-css/recommended',
    'plugin:prettier/recommended',
    'plugin:nuxt/recommended',
  ],
  plugins: ['prettier'],
  // add your custom rules here
  rules: {
    'nuxt/no-cjs-in-config': 'off',
    'no-console': 'off',
    'vue-scoped-css/require-scoped': 'error',
    'vue/component-name-in-template-casing': 'error',
    'prettier/prettier': ['error', { endOfLine: 'auto' }],
  },
}

我尝试运行应用程序时出现的错误是

$ npm run lint:fix

> v-moa-app@1.0.0 lint:fix
> npm run lint -- --fix


> v-moa-app@1.0.0 lint C:\Users2622018\moa_workspace\v-moa-app
> eslint --ext .js,.vue --ignore-path .gitignore . "--fix"

产生该错误的部分如下：

const decoded = new Buffer.from(encoded, 'base64').toString()

Answer 1

Buffer 上的 from 属性不是构造函数。这只是一个简单的方法，所以你不应该使用 new 。参见 the docs。您需要：

const decoded = Buffer.from(encoded, 'base64').toString()
