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，但我无法制造轮子。我尝试通过下载zip并运行python setup.py install手动重新安装分发版。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markerlib，看起来很有希望，但我不知道如何安全地使用它。目前我无法从PyPI安装很多任何，所以我给予积分以增加兴趣。

有任何帮助吗？我真的希望能够再次使用PyPI。

我选择了所选答案，因为最有可能来解决问题。我自己已经回到了x86 Python，所以我自己无法测试。因此，我鼓励未来的访问者尝试这个答案，但我自己无法对其进行测试。

Answer 1

可能是一个错误。退房：https://bugs.python.org/
您可以手动检查markers.py文件并尝试修复它。我认为sys_platform的引用必须更改为sys.platform

关于markerlib，你可以尝试一下 -

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

Answer 2

要修复此错误，我发现安装0.7.3版本的分发修复此问题。我也一直在升级setuptools和pip（所以也可能需要它们），但升级后分发这个错误终于消失了。

Answer 3

尝试删除pip并分发和设置工具，然后使用get-pip.py手动安装pip。

然后，从here下载setuptools，extract - ＆gt;在命令提示符下进入解压缩的文件夹并执行python setup.py install

然后，从here下载分发，提取 - ＆gt;在命令提示符下进入解压缩的文件夹并执行python setup.py install

Answer 4

我今天遇到了这个问题，尽管在OSX上。我已经运行--upgrade以及尝试完全卸载并重新安装它。

最终，虽然我进入了我的网站套餐，但看到了setuptools（18.1）的“正确”版本，因为它是旧的延迟版本（完全独立的版本15.1）它）。删除所有内容并重新安装setuptools为我修复它。

希望这有助于其他人！

Answer 5

我有一个旧的分发版本，它没有正确解析依赖项。它是用
