升级到 ubuntu 焦点后，我丢失了 python3 dist 文件。比如math, subprocess, random,thread等等...我在旧的 ubuntu bionic 上安装了一个自编译的 python 3.8，我以异常方式删除了它（删除的目录位于/usr/local/lib/python3.8）。后来我使用sudo apt remove python3 && sudo apt install python3. 有什么办法可以找回这些包裹吗？ubuntu 焦点会发生常见错误吗？

我在旧仿生中编译 python 3.8 的方式

  • 从 python 站点下载的 zip 文件
  • 使用配置和安装./configure && make && sudo make install

尝试使用 pip 安装某些东西时出错

newtron@newtron:~$ sudo pip3 install pip --upgrade

您可以使用 pip 安装这些 python 包。如果您的 ubuntu 上没有 pip，请sudo apt install python3-pip 在终端中执行pip install 'missing package'

这些 python 包也没有丢失，但它们没有随 python3 一起提供。您必须使用 wheel 包或使用 pip 将它们安装到您的 python 环境中

编辑 您可以尝试运行此命令，看看它是否解决了您的问题：

curl -sS https://bootstrap.pypa.io/get-pip.py | sudo python3

似乎 manu Ubuntu 用户遇到了 pip3 和 python 的问题。似乎您不能将包与 gloabl python 一起使用，因为它会导致一些奇怪的问题，但您可以使用包和 pip3 只是在虚拟环境中找到。您还可以在这里找到更多信息和更好的答案：pip3 install not working - No module named 'pip._vendor.pkg_resources'
