无法运行 TS 节点 + ES 应用程序 - 获取 `ERR_UNKNOWN_FILE_EXTENSION` 或 `new ERR_MODULE_NOT_FOUND`

Question

我正在尝试将我的代码编译为 ES 代码（在 package.json 中使用 "type": "module"，在 tsconfig.json 中使用 "module": "esnext"）。

我无法使用以下 3 种方法中的任何一种来运行它：

1. ts-node src/server.ts 结果：

TypeError [ERR_UNKNOWN_FILE_EXTENSION]: Unknown file extension ".ts" for /Users/ilmoi/Dropbox/crypto_bc/dbricks/mvp/server/src/server.ts
    at new NodeError (node:internal/errors:363:5)
    at Loader.defaultGetFormat [as _getFormat] (node:internal/modules/esm/get_format:71:15)
    at Loader.getFormat (node:internal/modules/esm/loader:105:42)
    at Loader.getModuleJob (node:internal/modules/esm/loader:243:31)
    at Loader.import (node:internal/modules/esm/loader:177:17)
    at Object.loadESM (node:internal/process/esm_loader:68:5)

this thread 中的哪个似乎是 ts-node 的问题。

1. 所以我尝试node --loader ts-node/esm ./src/server.ts 并得到这个：

(node:45543) ExperimentalWarning: --experimental-loader is an experimental feature. This feature could change at any time
(Use `node --trace-warnings ...` to show where the warning was created)
/Users/ilmoi/Dropbox/crypto_bc/dbricks/mvp/server/node_modules/ts-node/dist-raw/node-esm-resolve-implementation.js:383
    throw new ERR_MODULE_NOT_FOUND(
          ^

    at Loader.resolve (node:internal/modules/esm/loader:89:40)

但 src/app.ts 显然就在文件夹中！

1. 所以我尝试先用tsc 编译，然后运行node --loader ts-node/esm ./dist/src/server.js。我得到与（2）几乎相同的错误，除了这次缺少/Users/ilmoi/Dropbox/crypto_bc/dbricks/mvp/server/dist/src/app。这也没有意义，因为我可以在文件夹中看到它。

我该如何解决这个问题？我已经阅读了堆栈溢出的每个线程，但我没有选择。为什么运行一个 ES 节点应用这么难？

遇到了同样的问题。已通过关注this ts-node issue 修复。

TL;DR 只需将 .js 扩展添加到您的模块导入并使用 node --loader ts-node/esm src/index.ts 运行 ts-node
