Mocha 测试对原生 ES6 模块的“esm”支持

有一个很棒的帖子“使用 Mocha 和 esm 测试原生 ES 模块 https://web.archive.org/web/20220318155753/https://alxgbsn.co.uk/2019/02/22/testing-native-es-modules-mocha-esm/”亚历克斯·吉布森。谢谢他。

我尝试在我的项目中使用带有原生 ES 模块支持的 mocha，但遇到了 2 个不同的错误：

$ ./node_modules/mocha/bin/mocha --require esm './test/Util.test.js'

TypeError [ERR_VM_DYNAMIC_IMPORT_CALLBACK_MISSING]: A dynamic import callback was not specified.

根据我过去2小时了解到的情况：

包.json

{
    "type": "module"
}

tsconfig.json

{
    "compilerOptions": {
        "module": "esnext",
        "moduleResolution": "node",
    }
}

.mocharc.json

{
    "node-option": [
        "experimental-specifier-resolution=node",
        "loader=ts-node/esm"
    ]
}
