jspm + Karma JS - 从手表中排除文件但不从服务器中排除文件答案

我不知道如何让业力不关注文件夹 jspm_packages/ 中的更改。如果我尝试将“jspm_packages”添加到排除部分，则会出现以下错误：

调试 [web-server]：服务（缓存）：/Users/jm/dev/monka/node_modules/gulp-helpers/node_modules/karma-jspm/src/adapter.js PhantomJS 1.9.8 (Mac OS X 0.0.0) 错误 ReferenceError：找不到变量：系统在 /Users/jm/dev/monka/system.config.js:1 错误 [PhantomJS 1.9.8 (Mac OS X 0.0.0)]：ReferenceError：找不到变量：系统在 http://localhost:9876/base/system.config.js?31f6cba38ed6c99ea3e9b4bc926e8ecfd6de8bd7:1

这是我的 karma.conf.js

module.exports = function(config) {
  config.set({

    plugins: [
      'karma-jspm',
      'karma-jasmine',
      'karma-beep-reporter',
      'karma-verbose-reporter',
      'karma-babel-preprocessor',
      'karma-phantomjs-launcher'
    ],

    basePath   :  '',                 // base path that will be used to resolve all patterns (eg. files, exclude)
    frameworks : ['jspm', 'jasmine'], // frameworks to use available frameworks: https://npmjs.org/browse/keyword/karma-adapter
    browsers   : ['PhantomJS'],       // start these browsers available browser launchers: https://npmjs.org/browse/keyword/karma-launcher
    reporters  : ['progress', 'beep', 'verbose'/*, 'coverage'*/], // test results reporter to use possible values: 'dots', 'progress' available reporters: https://npmjs.org/browse/keyword/karma-reporter
    singleRun  : false,  // Continuous Integration mode if true, Karma captures browsers, runs the tests and exits
    autoWatch  : true,  // Enable / disable watching file and executing tests whenever any file changes
    colors     : true,  // enable / disable colors in the output (reporters and logs)
    files      : [],    // list of files / patterns to load in the browser

    jspm: {
      config     : 'system.config.js',
      loadFiles  : ['test-unit/**/*.js'],
      serveFiles : ['dist/**/**']
    },

    proxies: {
      '/base/app'      : '/base/dist/app',
      '/base/common'   : '/base/dist/common',
      '/jspm_packages' : '/base/jspm_packages'
    },

    exclude: [
      'coverage/**',
      'typings/**',
      'dist/**/*.js.map'
    ],

    // level of logging
    // possible values: config.LOG_DISABLE || config.LOG_ERROR || config.LOG_WARN || config.LOG_INFO || config.LOG_DEBUG
    logLevel: config.LOG_DEBUG,

    // preprocess matching files before serving them to the browser
    // available preprocessors: https://npmjs.org/browse/keyword/karma-preprocessor
    preprocessors: {
      'src/**/*.js' : ['babel', 'coverage']
    },

    babelPreprocessor: {
      options: { sourceMap:'inline', modules:'system' }
    },

    coverageReporter: { type:'html', dir:'coverage/' }

  });
};

【解决方案1】：

我认为，使用 Karma 无法排除也应提供的文件被观看。通过排除 jspm_packages，Karma 停止为位于 jspm_packages 文件夹中的 system.js 提供服务，因此未定义 System。

如果您不想在测试运行期间提供 jspm_packages，您可以尝试在创建自执行包后运行测试，然后只提供该包。
