I have an angular 6 application and I'm using karma + jasmine to run my tests. but when I run ng test I'm getting the following error:

错误TS2688中的错误:找不到'jest'的类型定义文件.

ERROR in error TS2688: Cannot find type definition file for 'jest'.

有人知道如何解决这个问题吗?

Any one knows how to solve this problem?

推荐答案

我没有意识到在我的tsconfig.spec.json中，我在types节点中使用的是jest而不是jasmin.另外，我的配置丢失了.

I didn't realized that in my tsconfig.spec.json I was using jest instead of jasmin in types node. Also, I had a missing configuration.

因此，我对此进行了更改:

So, I have changed from this:

{
  "extends": "./tsconfig.es5.json",
  "compilerOptions": {
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "outDir": "../out-tsc/spec",
    "module": "commonjs",
    "target": "es6",
    "baseUrl": "",
    "types": [
      "jest",
      "node"
    ]
  },
  "files": [
    "**/*.spec.ts"
  ]
}

对此:

{
  "extends": "./tsconfig.es5.json",
  "compilerOptions": {
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "outDir": "../out-tsc/spec",
    "module": "commonjs",
    "types": [
      "jasmine",
      "node"
    ]
  },
  "files": [
    "test.ts",
    "polyfills.ts"
  ],
  "include": [
    "**/*.spec.ts",
    "**/*.d.ts"
  ]
}

此更改解决了我的问题.

And this changes solves my problem.
