Angular Karma 引发未捕获的错误：缺少 jasmine.js

Question

我创建了一个新的 Angular 项目并希望使用 ng test 运行测试。但是我收到了很多 Pattern ** does not match any file 错误。

启动的 chrome 窗口 remains blank 我收到一个未捕获的 Chrome 错误：Missing jasmine.js。

简化控制台输出：

my-project>ng test

WARN [watcher]: Pattern "my-project\node_modules\karma-jasmine\lib\boot.js" does not match any file.

  }

我的 karma.conf.js 文件：

module.exports = function (config) {
  config.set({
    basePath: '.',
    frameworks: ['jasmine', '@angular-devkit/build-angular'],
    plugins: [
      require('karma-jasmine'),
      require('karma-chrome-launcher'),
      require('karma-jasmine-html-reporter'),
      require('karma-coverage-istanbul-reporter'),
      require('@angular-devkit/build-angular/plugins/karma')
    ],
    client: {
      clearContext: false // leave Jasmine Spec Runner output visible in browser
    },
    coverageIstanbulReporter: {
      dir: require('path').join(__dirname, '../coverage/my-project'),
      reports: ['html', 'lcovonly', 'text-summary'],
      fixWebpackSourcePaths: true
    },
    reporters: ['progress', 'kjhtml'],
    port: 9876,
    colors: true,
    logLevel: config.LOG_INFO,
    autoWatch: true,
    browsers: ['Chrome'],
    singleRun: false
  });
};

我想出并尝试做的事情：

• 模式包含反斜杠（我使用的是 Windows 10），但最后使用的是普通斜杠 （例如：my-project\node_modules\jasmine-core\lib/jasmine-core/jasmine.js）。这可能是问题所在。
• Chrome 错误提示缺少 jasmine.js 文件，所以我认为这与模式有关。
• 我尝试更改 karma.config.js 文件中的 basePath，但没有帮助

我对整个测试主题还是很陌生，我不知道如何解决这个错误。我需要改变什么？

Answer 1

好吧，在进一步搜索问题后，我发现我的项目路径对因果报应无效： F:\Projects\2019.04.05 - 2019.04.08[Angular] My Project\my-project

导致问题的字符是方括号 [ ]

现在一切正常！
