由于错误行Using cached backports.zoneinfo-0.2.1.tar.gz (74 kB)（可能缓存的版本已损坏/旧，与其他软件包不兼容），我尝试了clearing my pip cache-但除了删除该行外，这没有任何区别

上下文

我在安装Python 3.9后遇到了依赖性问题（在这里和这里讨论）。链接帖子中的问题已经修复，但我正在卸载并重新安装我的pip安装包，以确保它们与我的新python版本兼容。我正在尝试使用的一个包是backports-zoneinfo。我知道我是don't really need this，但我还是打算保留它，以防我写的东西需要与旧的python版本兼容。

问题：

我已经卸载了backports-zoneinfo，然后试图重新安装它，但在这篇文章的底部得到错误消息。然后我按照错误信息安装了build tools 2022，并试图再次重新安装backports-zoneinfo，但得到了相同的错误。有人能帮我诊断和解决这个问题吗？

卸载消息：

要真正修复这个特定的错误，你需要在你的windows机器上有一个工作的编译器：
需要Microsoft Visual C++ 14.0或更高版本。使用“Microsoft C++ Build Tools”获取：https://visualstudio.microsoft.com/visual-cpp-build-tools/
为此，您需要按照链接，下载并安装构建工具，然后重试。
这个特殊的pip包没有python3.9的whl文件，同时有一个源发行版，其中有用C/C++编写的部分。因此，pip现在需要调用编译器来为您的机器构建源代码发行版。
为了避免这种情况，你有几个选择：
1.您可以尝试使用conda install -c conda-forge backports.zoneinfo安装相同的软件包，而不是pip
1.由于zoneinfo已经成为stdlib的一部分，您也可以尝试将import backports.zoneinfo替换为import zoneinfo。使用此方法，您将不需要进一步安装。
