Error [ERR_REQUIRE_ESM]: require() of ES Module - Vue 3 Typescript

Question

I am currently integrating mdx into my vue 3 typescript project. However, I get the following error when configuring the vue.config.js:

yarn run v1.22.11
$ vue-cli-service serve

ERROR  Error loading C:\Users\Jannik\Desktop\mdx-vue3\vue.config.js:
ERROR  Error [ERR_REQUIRE_ESM]: require() of ES Module C:\Users\Jannik\Desktop\mdx-vue3\vue.config.js from C:\Users\Jannik\Desktop\mdx-vue3\node_modules\@vue\cli-shared-utils\lib\module.js not supported.
Instead change the require of vue.config.js in C:\Users\Jannik\Desktop\mdx-vue3\node_modules\@vue\cli-shared-utils\lib\module.js to a dynamic import() which is available in all CommonJS modules.

My vue.config.js:

import remarkGfm from "remark-gfm";

module.exports = {
chainWebpack: config => {
    config.module
        .rule('mdx')
        .test(/\.mdx?$/)
        .use('babel-loader')
        .loader('babel-loader')
        .options({plugins: ['@vue/babel-plugin-jsx'], /* Other options… */})
        .end()
        .use('@mdx-js/loader')
        .loader('@mdx-js/loader')
        .options({jsx: true, remarkPlugins: [remarkGfm], /* otherOptions… */})
        .end()
    }
}

My package.json:

{
  "name": "mdx-vue3",
  "version": "0.1.0",
  "private": true,
  "type": "module",
  "scripts": {

    "typescript": "~4.1.5"
  }
}

The error when im not using "type": "module" :

C:\Users\Jannik\Desktop\mdx-vue3\vue.config.js:1
import remarkGfm from "remark-gfm";
^^^^^^

SyntaxError: Cannot use import statement outside a module

My tsconfig.json:

{
  "compilerOptions": {
    "target": "esnext",
    "module": "esnext",
    "strict": true,
    "jsx": "preserve",
    "importHelpers": true,
    "moduleResolution": "node",
    "experimentalDecorators": true,
    "skipLibCheck": true,
    "esModuleInterop": true,
    "allowSyntheticDefaultImports": true,

    ],
    "paths": {
      "@/*": [
        "src/*"
      ]
    },
    "lib": [
      "esnext",
      "dom",
      "dom.iterable",
      "scripthost"
    ]
  },
  "include": [
    "src/**/*.ts",
    "src/**/*.tsx",
    "src/**/*.vue",
    "tests/**/*.ts",
    "tests/**/*.tsx"
  ],
  "exclude": [
    "node_modules"
  ]
}

I tried the whole thing with node.js v14 and v16. I also deleted my node_modules each time.

If i rename the file to vue.config.mjs the errors disappear, but then the mdx-loader does not work anymore.

Answer 1

The problem is yow module.exports= module.exports is used with Commonjs but you have modules in yow package json. You need to change it to export default

Answer 2

Updating the devDependencies and renaming vue.config.js to vue.config.mjs fixed the error:
