angular universal找不到名称'expect‘

Question

我需要些帮助。当我运行npm run build:ssr && npm run serve:ssr时，我得到以下错误

TS2304: Cannot find name 'expect'.
TS2304: Cannot find name 'it'.
TS2304: Cannot find name 'fail'.

npm ERR! code ELIFECYCLE
npm ERR! errno 2

npm ERR! Exit status 2

npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

Answer 1

在tsconfig.json文件中，添加以下行：

"exclude": [
    "node_modules",
    "e2e",
    "**/*.spec.ts"
  ]

这告诉编译器在编译时忽略node_modules和e2e目录以及任何.spec文件。在集成Universal之后，我在Angular 8中遇到了这个问题，这些方法可以在每个组件的规范文件中找到。
