【问题描述】：
当我运行测试命令时，我正在使用 mocha \"mocha\": \"^7.2.0\", 进行单元测试：
\"test\": \"cross-env TS_NODE_PROJECT=\'test/tsconfig.test.json\' mocha test/**/**\",
显示如下错误：
➜ js-wheel git:(main) ✗ yarn test
yarn run v1.22.17
$ cross-env TS_NODE_PROJECT=\'test/tsconfig.test.json\' mocha test/**/**
TypeError [ERR_UNKNOWN_FILE_EXTENSION]: Unknown file extension \".ts\" for /Users/xiaoqiangjiang/source/reddwarf/frontend/js-wheel/test/utils/time.test.ts

有人告诉我可以删除package.json 中的\"type\": \"module\"，但我无法删除它，我需要使用es6 导入。我检查了 tsconfig.json 并且 esModuleInterop 配置已经是真的。我应该怎么做才能解决这个问题？这是tsconfig.json：
{
\"compilerOptions\": {
/* Language and Environment */
\"target\": \"es5\", /* Set the JavaScript language version for emitted JavaScript and include compatible library declarations. */
/* Modules */
\"module\": \"esnext\", /* Specify what module code is generated. */
/* Emit */
\"declaration\": true, /* Generate .d.ts files from TypeScript and JavaScript files in your project. */
\"outDir\": \"./dist\",
\"lib\": [ \"DOM\",\"ES2015\" ], /* https://stackoverflow.com/questions/43555378/ts-an-async-function-or-method-in-es5-es3-requires-the-promise-constructor */
\"esModuleInterop\": true,
\"moduleResolution\":\"node\", /* Emit additional JavaScript to ease support for importing CommonJS modules. This enables `allowSyntheticDefaultImports` for type compatibility. */
// \"preserveSymlinks\": true, /* Disable resolving symlinks to their realpath. This correlates to the same flag in node. */
\"forceConsistentCasingInFileNames\": true, /* Ensure that casing is correct in imports. */
/* Type Checking */
\"strict\": true, /* Enable all strict type-checking options. */
\"skipLibCheck\": true,
\"baseUrl\": \"src\",
\"paths\": {
\"@net/*\":[\"net/*\"],
\"@auth/*\":[\"auth/*\"],
\"@utils/*\":[\"utils/*\"],
\"@model/*\":[\"model/*\"],
},
// Note: To transform paths for both the output .js and .d.ts files, you need both of the below entries
\"plugins\": [
// Transform paths in output .js files
{ \"transform\": \"typescript-transform-paths\" },
{ \"transform\": \"ts-transformer-keys/transformer\" },
// Transform paths in output .d.ts files (Include this line if you output declarations files)
{ \"transform\": \"typescript-transform-paths\", \"afterDeclarations\": true }
]
},
\"exclude\": [
\"dist\"
]
}
我也试过这个命令：
\"test\": \"mocha -r ts-node/register test/**/**\",
仍然没有工作。还尝试使用 ts-mocha：
\"test\": \"ts-mocha -p tsconfig.json test/**/**\",
不工作。调整 tsconfig.json：
\"module\": \"CommonJS\"
仍然没有工作。

您正在设置
TS_NODE_PROJECT，但直接运行mocha，而不是ts-mocha、ts-node或node -r tsnode/register。是否有其他一些配置，您希望 Node 在没有显式配置的情况下处理 TypeScript？
