Python &引用；警告：scheme.data的值不匹配；当我尝试更新pip或安装软件包时

我有一台M1 Mac，我刚刚注意到，当我尝试升级

pip

或安装任何软件包时，我会收到一系列警告：

请告知。

降级到早期版本的pip为我修复了它：

python-mpipinstallpip==21.0.1

（这里是一个pip维护者！）

更新：通过将此消息的日志记录级别从“警告”降低到“调试”，PIP21.1.1已经发布，并修复了此问题。现在，只有使用

--verbose

运行pip的用户才能看到它

---

此警告本身无害，不会影响任何安装逻辑。您可以安全地使用当前的pip，暂时忽略此警告

对于那些想要快速消除此警告的人：

python-m pip install pip==21.0.1

——您现在可以使用旧版本的pip。这在IMO中是不必要的，但是你可以选择你的毒药（与旧版本的pip相比，有些警告需要忽略）

---

对于那些想了解更多的人：添加此警告是因为我们希望在将来进行过渡时，能够揭示可能发生的问题

出于历史原因（uhm…Python2），pip使用了

distutils.sysconfig

来获取有关在何处安装Python包的信息。该模块在功能上可以替换为添加到Python 3.2中的Python标准库中的模块。但是，Python发行商对其进行了修补（而不是sysconfig），以提供另一种“默认安装方案”

不推荐distutils，它将从Python标准库中删除<基于代码>distutils的安装是Python打包社区一段时间以来一直试图反对和删除的东西

---

我们一直在与许多分销商合作，让他们修复补丁，以便将来的安装可以过渡到使用

sysconfig

作为他们的真实来源。此消息是“从损坏的Python安装的用户处获取信息”的一部分。您可能已经注意到，配置不同的

distutils.sysconfig

和

sysconfig

的Python安装比我们预期的要常见得多

对于那些未能运行

python-m pip install pip==21.0.1

（例如，返回了相同的错误消息，如

ValueError:check\u hostname requires server\u hostname

），您可以尝试禁用系统代理并重试该命令（如果您使用的是shadowsocks、v2ray等代理）。

如果您，如果您对anaconda做了任何更改（重新安装、更新、删除），那么问题可能是您的pip试图使用哪种python

如果查看pip（/usr/local/bin/pip3），shebang可能指向不同的python文件路径

---

我也遇到了同样的问题，我通过更改pip3文件中的python引用解决了这个问题。

有趣的是，pip甚至抱怨自己：
