我认为 Python 有问题（路径、版本等）
maskalev@maskalev-Aspire-A514-54:~$ pip install pyparsing
Defaulting to user installation because normal site-packages is not writeable
Requirement already satisfied: pyparsing in ./.local/lib/python3.10/site-packages (3.0.9)
maskalev@maskalev-Aspire-A514-54:~$ python3 -c "import sys; print(sys.path)"

我会很高兴收到任何建议。我将根据要求发送任何其他信息
答案1
您的本地用户安装与系统软件无关。您不能使用 pip 安装系统范围的 python 软件包。
由于 Ubuntu 确实使软件中心依赖于该python3-pyparsing软件包，因此您一定在没有dpkg/apt注意到的情况下以某种方式删除了该软件包（或只是其内容？）。您试图解决此问题的事实pip让我预感您在某个地方做了类似的事情sudo pip uninstall并破坏了您的系统。然后你很可能会在途中遇到更多破碎的事情；删除 pyparsing 不太可能不会同时删除其他关键模块。也许您实际上覆盖了python3系统使用的可执行文件？
您可以尝试解决您眼前的问题sudo apt-get reinstall python3-pyparsing，但我担心 python 的多个版本会扰乱您的路径，并且如果我猜测您pip在系统中混合安装，从而以清理起来繁琐的方式破坏了它起来，你的最快的解决方案可能是保存用户的主页并重新设置 Ubuntu。您的成功可能确实因您投入的时间而异。
