我今天刚开始也得到同样的东西......我最近更新了JSPM到v0.16.30。您最近的任何变化都可能有助于缩小原因？有趣的是，我刚才问过我的同事测试他的代码，它的工作... 唯一的区别是我们的操作系统 - 我：优胜美地和他：埃尔卡皮坦。 –

嗨凯文 - 我正在运行埃尔卡皮坦和“jspm”：“0.16.13”，是的，即使我的同事能够运行它，但他在优胜美地。我认为我做了npm或jspm安装然后它出现了，但它不会去，即使我恢复，清理我的node_modules – Abhi

ABHI，

我花了一个很好的下午，发现一个解决办法，到我已经承认什么是最好的猜测的问题，我有零理念为什么会发生。

我的问题是在Karma配置中的serveFiles和loadFiles中的球体。为了解决我做了我自己的globbing使用glob.sync生成阵列，因为我需要和这个工作！

module.exports = function(config) { 

    var options = {cwd:"www"}; 
    var glob = require("glob"); 
    var filesToServe = glob.sync("./src/**/*[email protected](js|ts|css|scss|html)", options); 
    var specsToLoad = glob.sync("./src/**/*[email protected](spec.ts)", options).map(function(file){ 
     return file.substr(2); 
    }); 

    config.set({ 
     basePath: 'www', 

     frameworks: ['jspm', 'jasmine'], 

     jspm: { 
      config: './test/config.js', 
      loadFiles: ['test/boot.ts'].concat(specsToLoad), 
      serveFiles: filesToServe, 
     }, 

     files: [ 
     'http://cdn.auth0.com/js/lock-8.2.min.js' 
     ], 

     proxies: { 
      '/src/': '/base/src/', 
      '/.test/': '/base/.test/' 
     }, 

     port: 9876, 

     logLevel: config.LOG_DISABLE, 

     colors: true, 

     autoWatch: true, 

     browsers: ['Chrome'], 

     plugins: [ 
      'karma-jspm', 
      'karma-jasmine', 
      'karma-chrome-launcher', 
      'karma-spec-reporter' 
     ], 

     reporters: ['spec'], 

     singleRun: true 
    }); 
};

的filesToServe和specsToLoad对待略有不同，我需要从文件中删除./加载，因为它与内部SystemJS的装载干扰（这可以通过它试图加载.ts.js识别文件）。此外，我已将我的工作放在了一个子文件夹'www'中，您可能不需要删除cwd。

希望你能看到我在这里做了什么，它可以帮助你找到解决方法。如果有人知道为什么像glob这样的东西突破我很想知道。

为了证明这是水珠我做了一个简单的测试，使用

require(glob)("src/**/*",function(file){ console.log(file); });

这引发了同样的错误，显然别无他用太多的文件或文件表的问题。如果这在其他地方弹出，我将不得不再次安装操作系统，我想。然而，在我的代码库中，我在其他地方使用glob，没有任何问题。我曾想知道是否可能是使用“同步”版本的流程之间的区别...

一天涉水选项最终在这里......我希望找到一个更好的答案。

凯文，我的男人 - 你只是让我的一天:)这很有趣，因为我在想同样的事情来自Karma团队的关于这个全局问题的评论。我尝试使用全局数组，但它是相同的 – Abhi

var globArray = require（“glob-array”）; var loadFiles = globArray.sync（['src/app/app.js'，'src/app/**/*。spec.js']）; var serveFiles = globArray.sync（['src/app /**/*.+（js | html | css | json）']）; – Abhi
