问题说明
每当我尝试安装软件包时，例如 pip3 install PyQt5，该命令都会失败，并显示有关 /tmp 目录中缺少目录的消息
Whenever I try to install a package, for example pip3 install PyQt5 the command fails with a message about a missing directory in the /tmp directory
pip3 install PyQt5

Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-install-0shdy0kn/PyQt5/
当我查看 /tmp 目录时，不存在 pip-install-xxxxxxx 目录，并且看起来进程根本没有创建它们.
When I look in the /tmp directory no pip-install-xxxxxxx directories exist and it looks like the process doesn't create them at all.
正确答案
作为快速修复，您可以 sudo apt-get install python3-pyqt5
As a quick fix you can sudo apt-get install python3-pyqt5
但是为了你的问题.任何包裹都会发生这种情况吗?
But for the sake of your question. Does this happen with any package?
您可以尝试安装以下任何一个来看看它是否有效，这些只是简单的示例.
Can you try installing any of the following just to see if it works, these are just quick examples.
pip3 install numpy==1.18.1
pip3 install pandas==0.25.3
pip3 install pep8==1.7.1
pip3 install pika==1.1.0
一个原因可能是 PyQt5 将与 python 2 一起使用，因此可能仅适用于 pip install PyQt5
One reason could be that PyQt5 is to be used with python 2 and hence might only work with pip install PyQt5
