Question

我是节点和编写服务器端代码的新手，所以请耐心等待。目前，我正在使用Typescript编写节点lambda。为了在我的项目中使用它，我需要将typescript模块作为依赖项，因此我将它们列在我的package.json文件中，并且它们与npm install一起安装。接下来我运行npm test并收到此错误日志。

This is usually the result of a faulty configuration or import. Make sure there is a `.js`, `.json` or another executable extension and loader (attached before `ts-node`) available alongside     `/Users/amohnacs/Developer/git/example-data-sync/node_modules/any-promise/implementation.d.ts`.

这是我的package.json

}

它告诉我，我的项目配置不正确，但是在ts-node中出现了错误的路径。在我的项目配置中是否存在我遗漏或不正确的内容，或者我可能使用了错误版本的ts-node或Typescript。

提前谢谢。

Answer 1

在 package.json 的 nyc.exclude 部分添加 node_modules 。

"nyc": {
  "exclude": [
    "spec/**/*.spec.ts",
    "typings",
    "node_modules"
  ],

Answer 2

就我而言，以下解决了问题，但不排除 .ts 文件：

我安装了 ts-jest，请参阅说明 here
然后，在 jest.config.js 中，我添加了

globals: {
  'ts-jest': {
    isolatedModules: true
  },
},
