sys_platform未定义x64 Windows

Question

这一直困扰着我.我最近升级到x64 Python,我开始收到此错误(示例pip install).

包裹安装得很好,但我不能建造轮子.我尝试通过下载zip并运行来手动重新安装分发python setup.py install.安装奇妙,没有任何障碍.但我仍然有上述问题.

如何重新定义sys_platform？

好吧,我回滚到x86 good ole 32 bit Python,我仍然有问题.这真的很令人担忧,因为重新安装后我无法重置它.我看了一下看起来很有前景的markerlib,但我不知道如何安全地使用它.目前我无法从PyPI 安装任何东西,所以我给予积分以增加兴趣.

有帮助吗？我真的希望能够再次使用PyPI.

我选择了所选答案,因为它最有可能解决问题.我自己已经回到了x86 Python,所以我自己无法测试.因此,我鼓励未来的访客尝试这个答案,但我没有能够测试它.

1. 可能是一个bug.退房:https://bugs.python.org/
2. 您可以手动检查markers.py文件并尝试修复它.我认为有sys_platform必要将其改为sys.platform

3. 关于markerlib,你可以试试这个 -

   import markerlib
   marker = markerlib.compile("sys.platform == 'win32'")
   marker(environment=markerlib.default_environment(), override={'sys.platform':'win32'})
