我把代码放在这里，并定期上传到PIP和anaconda。然而，自从我添加了这行代码到setup.py后，conda就无法编译。
所以PIP一切正常，我像往常一样执行python setup.py sdist也没有问题。但是，当我执行conda build .时，就会出现错误：
ERROR: Could not find a version that satisfies the requirement pytest-runner
ERROR: No matching distribution found for pytest-runner
我在网络上看到了这个错误，但通常是安装时出现的，而不是上传时出现。此外，解决方案似乎只是安装库，但在我的情况下已经安装了：
$ conda install -c anaconda pytest-runner
