javascript - Mocha 测试 'esm' 支持原生 ES6 模块

Question

Alex Gibson 有一篇很棒的帖子“Testing native ES modules using Mocha and esm”。谢谢他。
我尝试在我的项目中使用 mocha 和原生 ES 模块支持，但我遇到了 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.

Answer 1

根据我在过去 2 小时中学到的知识:
包.json

{
    "type": "module"
}

tsconfig.json

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

.mocharc.json

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