问题描述
我当前正在使用Reaction、Tyescript、Style Components、webpack等设置样板，尝试运行eslint时出错：
错误：必须使用IMPORT加载ES模块
以下是错误的更详细版本：
/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
错误出现在我的每个.js和.ts/.tsx文件中，在这些文件中我只使用import，或者该文件甚至根本没有导入。我理解错误的意思，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。
这里是我的Package.json，我在其中使用npm run lint:eslint:quiet触发Linter：

}
}
我不确定是否相关，但我的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？在谷歌上搜索该错误不会显示任何有用的论坛或引发的错误，其中大多数只是声明不要在您的文件中使用require，而我没有。

我认为问题在于您正在尝试使用已弃用的babel-eslint parser，该版本上次更新是在一年前，它看起来不支持推荐答案模块。更新到latest parser似乎起作用，至少对于简单的植绒是有效的。
因此，请执行以下操作：
- 在Package.json中，将行
"babel-eslint": "^10.0.2",更新为"@babel/eslint-parser": "^7.5.4",。这可以与上面的代码一起使用，但使用最新版本可能更好，在编写本文时，最新版本是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(位于"ecmaVersion": 8,下方)(我需要此文件，或者Babel正在查找我没有的配置文件) - 运行命令以链接文件
然后，对于只有您的两个配置文件的我来说，错误就会消失，并且我会得到相应的线条错误。
