pip3安装命令重复失败，无法创建文件"/tmp/pip-install-xxxxx/package" [英] pip3 installation commands repeated failure to create file '/tmp/pip-install-xxxxx/package'

问题描述

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/

当我在/tmp目录中查找时，没有pip-install-xxxxxxx目录存在，看来该过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.

推荐答案

作为快速解决方案，您可以sudo apt-get install python3-pyqt5

As a quick fix you can sudo apt-get install python3-pyqt5

但是为了您的问题.任何包装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工具只是为了看看是否可行，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与python 2一起使用，因此可能仅与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
