【中文标题】ESlint - 错误:必须使用导入来加载 ES 模块【英文标题】:ESlint - Error: Must use import to load ES Module 【发布时间】:2021-12-01 20:58:01 【问题描述】:我目前正在使用 React、Typescript、样式化组件、webpack 等设置样板,但在尝试运行 eslint 时出现错误:
错误:必须使用 import 来加载 ES 模块
这是一个更详细的错误版本:
/Users/ben/Desktop/development projects/react-boilerplate-styled-context/src/api/api.ts
0:0 error Parsing error: Must use import to load ES Module: /Users/ben/Desktop/development projects/react-boilerplate-styled-context/node_modules/eslint/node_modules/eslint-scope/lib/definition.js
require() of ES modules is not supported.
require() of /Users/ben/Desktop/development projects/react-boilerplate-styled-context/node_modules/eslint/node_modules/eslint-scope/lib/definition.js from /Users/ben/Desktop/development projects/react-boilerplate-styled-context/node_modules/babel-eslint/lib/require-from-eslint.js is an ES module file as it is a .js file whose nearest parent package.json contains "type": "module" which defines all .js files in that package scope as ES modules.
Instead rename definition.js to end in .cjs, change the requiring code to use import(), or remove "type": "module" from /Users/ben/Desktop/development projects/react-boilerplate-styled-context/node_modules/eslint/node_modules/eslint-scope/package.json
我的每个 .js 和 .ts/ .tsx 文件中都会出现错误,我只使用 import
或者该文件根本没有导入。我明白错误在说什么,但我不知道为什么会抛出它,而实际上我在某些文件中只使用导入甚至根本不使用导入。
这是我的 package.json,我使用 npm run lint:eslint:quiet
触发 linter:

我不确定是否相关,还有我的 tsconfig.eslint.json 文件:
"extends": "./tsconfig.json",
"include": ["./src/**/*.ts", "./src/**/*.tsx", "./src/**/*.js"],
"exclude": ["node_modules/**", "build/**", "coverage/**"]
不确定以前是否有人遇到过这种情况?谷歌搜索错误不会显示任何有用的论坛或提出的错误,其中大多数只是声明不要在您的文件中使用require
,而我不是。
【问题讨论】:
【参考方案1】:我认为问题在于您正在尝试使用已弃用的babel-eslint parser,最近一次更新是一年前,看起来它不支持 ES6 模块。更新到 latest parser 似乎有效,至少对于简单的 linting。
所以,这样做:
在 package.json 中,将行"babel-eslint": "^10.0.2",
更新为 "@babel/eslint-parser": "^7.5.4",
。这适用于上面的代码,但最好使用最新版本,在撰写本文时为 7.16.3。
从文件夹中的终端/命令提示符运行npm i
在 .eslintrc 中,将解析器行 "parser": "babel-eslint",
更新为 "parser": "@babel/eslint-parser",
在 .eslintrc 中,将 "requireConfigFile": false,
添加到 parserOptions 部分(在 "ecmaVersion": 8,
下方)(我需要这个或 babel 正在寻找我没有的配置文件)
运行命令对文件进行 lint 处理
然后,对于我来说只有你的两个配置文件,错误消失了,我得到了适当的 linting 错误。
【讨论】:
我也有同样的问题,在哪里可以找到.eslintrc文件? 它通常与 package.json 在同一个文件夹中。但是,它可能在其他地方。从命令行可以指定它,或者 eslint 将在您正在 linting 的文件的文件夹或任何父文件夹中查找。如果您使用的是框架或 IDE 插件,它也可能在其他地方!它也不必称为 .eslintrc:there are several options for other names and formats,包括将配置放入 package.json 本身。简而言之,如果这更简单一点,将对每个人都有帮助。 不幸的是,这对我不起作用。有没有人成功使用过这个解决方案? 是的@DavidH - 它对我有用。尝试重新启动代码编辑器以反映更改,或尝试删除node_modules
文件夹并重新安装 npm。它应该可以工作。【参考方案2】:
“@babel/eslint-parser”依赖于“@babel/core”。所以在“npm install @babel/eslint-parser -S”之后,你应该npm i @babel/core -S
