我用 angular-cli 创建了一个项目。 单元测试在我的本地系统中运行良好。 当我在构建过程中运行测试时，在 VSTS 中出现以下错误:

karma 配置如下所示:

package.json 如下:
"private": true, "dependencies": { "@angular/animations": "^4.2.4", "@angular/common": "^4.2.4", "@angular/compiler": "^4.2.4", "@angular/core": "^4.2.4", "@angular/forms": "^4.2.4", "@angular/http": "^4.2.4" }, "devDependencies": { "@angular/cli": "1.4.7", "@angular/compiler-cli": "^4.2.4", "@angular/language-service": "^4.2.4", "@types/jasmine": "~2.5.53", "@types/jasminewd2": "~2.0.2", "@types/node": "~6.0.60", "codelyzer": "~3.2.0", "jasmine-core": "~2.6.2", "jasmine-spec-reporter": "~4.1.0", "karma": "~1.7.0", "karma-chrome-launcher": "~2.1.1", "karma-cli": "~1.0.1", "karma-coverage-istanbul-reporter": "^1.2.1", "karma-jasmine": "~1.1.0" } }
感谢任何解决错误的帮助。
提前致谢。
最佳答案
首先，您不需要在 VSTS 代理上全局安装 Angular CLI，您只需运行:
npm run ng -- t - 它将使用 Angular CLI 的本地项目版本，无论它是什么版本。
第二个VSTS does not support Headless chrome yet
因此，请尝试设置 browsers: ['Chrome'] 而不是使用普通的 Chrome 浏览器。
您也可能想尝试VSTS Chromium Build Task (目前处于预览阶段，因此可能不起作用)
FYI currently on our project we are rinning tests on VSTS with normal Chrome and have no problems with that. In order to do that you have to install Chrome browser on your build agent machine https://learn.microsoft.com/en-us/vsts/build-release/concepts/agents/agents.
