Angular6

Question

我在 angular 项目中遇到问题运行ning“ng 测试”。当我运行我得到以下输出：

ERROR in ./node_modules/selenium-webdriver/lib/http.js Module not found: Error: Can't resolve 'fs' in 'C:\Users\test\Desktop\ui-portal\node_modules\selenium-webdriver\lib' @ ./node_modules/selenium-webdriver/lib/http.js 28:11-24 @ ./node_modules/selenium-webdriver/http/index.js @ ./src/app/container/container.component.spec.ts @ ./src .spec.ts$ @ ./src/test.ts

-

ERROR in ./node_modules/selenium-webdriver/lib/devmode.js Module not found: Error: Can't resolve 'fs' in 'C:\Users\test\Desktop\ui-portal\node_modules\selenium-webdriver\lib' @ ./node_modules/selenium-webdriver/lib/devmode.js 25:11-24 @ ./node_modules/selenium-webdriver/lib/http.js @ ./node_modules/selenium-webdriver/http/index.js @ ./src/app/container/container.component.spec.ts @ ./src .spec.ts$ @ ./src/test.ts

我一直在寻找答案，但找不到任何有用的答案 - 以前有人遇到过这个问题吗？我的package.json文件如下：

在此先感谢您的指点！真的没有在这方面取得进展:(

Answer 1

从 ts 文件中删除 import 'jasmine'。

如果编辑抱怨缺少类型 jasmine

 "compilerOptions": {
    "types": [
      "jasmine",
      ...
    ]
 }

Answer 2

我通过运行依次执行以下命令解决了这个问题：

npm install --save-dev @types/jasmine

npm install

npm audit fix

现在运行 ng 测试 实际运行我的单元测试！ :-D

Answer 3

出于某些原因，我的 IntelliJ 添加了：

import { beforeEach } from 'selenium-webdriver/testing';

导致问题的原因。删除它解决了我的问题。

Answer 4

我在

上的 ng 测试中遇到了同样的问题

Angular CLI: 6.1.2 Node: 8.9.1

我的问题是使用

wrong HttpClient. import in my test file.

确保您的 HttpClient 来自 '@angular/common/http'; 而不是从 Selenium 导入。

希望这对您有所帮助:)

Answer 5

我遇到了同样的问题，因为它从 'protractor' 而不是 angular-core

导入了 EventEmitter

Answer 6

当我允许 Visual Studio 代码自动导入 EvenEmitter 时，我遇到了同样的问题，如下所示：

从'protractor'导入{EventEmitter}；

我通过更改导入位置来修复它，如下所示：

从'@angular/core'导入{EventEmitter};

希望这对某人有所帮助。
