Question

我更新了angular-cli版本，我现在拥有的当前版本为1.0.0-beta.32.3 [1.0.0-beta.26]。但是，在运行test脚本（即npm run test）时会抛出以下错误：

Path must be a string. Received undefined

几天前在这里发现了一个类似的问题：https://github.com/angular/angular-cli/issues/4815

对我来说似乎是一个webpack问题，但我真的不能说。我希望这可以帮助每个人遇到同样的问题。

更新

我有同样的问题，更新karma.conf.js修复它，如下所述：https://github.com/angular/angular-cli/issues/4815

将angular-cli替换为@angular/cli中的karma.conf.js，您应该好好去。

angular-cli Path必须是一个字符串。收到undefined
