为什么因果报应显示距离误差？

Question

我正在为茉莉花中的angularjs编写测试用例，并使用业力作为测试跑步者。以前，一切都很好，但突然之间，这个RangeError:错误的长度！发生了。我甚至不知道如何调试它发生在哪里。请帮忙..。

这似乎是最新的karma版本(0.13.16)中的一个bug。检查这个问题：https://github.com/karma-runner/karma/issues/1768。

如果您已更新到karma@0.13.16，并且启用了coverage报告，则会遇到此问题。

现在这个问题还没有解决，所以您可以降级为karma@0.13.15，或者禁用coverage报告程序。当问题解决后，可能会发布一个新的补丁版本。
