我从它的存储库中克隆了该死的源代码（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
它工作得很好。之后尝试通过以下方式运行测试：
py.test
得到以下错误：

我怀疑这个工具是为只在 Linux 和类 unix 命令行上工作而编写的。
- 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？
我想开始从事开源项目以成为更好的开发人员。将 Linux 用于我的开发任务不是问题。如果我知道更有经验的开发人员对此的看法，那将对我有所帮助。
