javascript - karma : Move Folder -> Missing Error Handler on Socket?

Question

对于由 Karma 0.13.22 运行的 Angular 2.0 项目，我有一组有效的单元测试，连接到带有 Socket.io 1.4.5 的 Chrome 48 浏览器。我在这种配置下进行测试，效果很好:

app/
tests/app
karma-test-shim.js
karma.conf.js

然后，在不更改任何代码的情况下，我移动了一个文件夹:

source/app/
tests/app
karma-test-shim.js
karma.conf.js

...然后我更新了karma-test-shim.js和 karma.conf.js使用新路径。

现在测试甚至没有运行，我得到这个错误:

Missing error handler on `socket`.
TypeError: (msg || "").replace is not a function
  at /home/spryno724/projects/portfolio/node_modules/karma/lib/reporter.js:45:23
  at onBrowserError (/home/spryno724/projects/portfolio/node_modules/karma/lib/reporters/base.js:58:60)
  ... more stack trace ...

11 03 2016 20:24:11.038:WARN [Chrome 48.0.2564 (Windows 10 0.0.0)]: Disconnected (1 times)

知道是什么原因造成的吗？ 唯一改变的是文件夹路径。

引用您的项目 https://github.com/oliver-spryn/portfolio

您可以尝试更改您的 karma-test-shim.js。在 System.config 下，将格式:'register' 更改为格式:'cjs'。

我复制了你的 karma.conf.js + karma-test-shim.js 并创建了简单的 proj 来模拟你遇到的问题(按照上面的修复)。 https://github.com/phhoangbao/angular2-test
