Question

我创建了一个新的angular项目，并希望通过ng test运行测试。但是我遇到很多Pattern ** does not match any file错误。

启动的Chrome窗口remains blank出现了一个未捕获的Chrome错误：Missing jasmine.js。

简化的控制台输出：

my-project>ng test

  }

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：

这些模式包含反斜杠（我使用的是Windows 10），但最后使用了正常的斜杠（例如： my-project \ node_modules \ jasmine-core \ lib / jasmine-core / jasmine.js ）。这可能是问题所在。
Chrome错误表明jasmine.js文件丢失，因此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

对于整个测试主题，我还是一个新手，我不知道如何解决此错误。我必须更改什么？

在进一步寻找问题之后，我发现我的项目之路对因果报应无效： F:\Projects\2019.04.05 - 2019.04.08[Angular] My Project\my-project

引起问题的字符是方括号[]

现在一切正常！
