我克隆了thefuck源代码来自它的存储库（这是真正的项目名称，是的，我知道......）。尝试通过以下命令安装它以进行开发：
pip install -r requirements.txt
python setup.py develop
效果很好。后来尝试通过以下方式运行测试：
py.test
出现以下错误：

我怀疑这个工具被编写为只能在 Linux 和类 UNIX 命令行上运行。
- 出现这个错误的原因是什么？
- 如果它是未针对 Windows 实现的 python 库的一部分，是否有任何快速修复方法？
我想开始从事开源项目，成为一名更好的开发人员。使用 Linux 来完成我的开发任务不是问题。如果我了解更有经验的开发人员对此的看法，这会对我有所帮助。
