我尝试安装的程序需要安装 PyQt5 5.15.0 ，这给了我这个错误.奇怪的是，最新版本的 PyQt5 (5.15.2) 可以正常安装，但是这个程序特别需要 5.15.0.
A program I am trying to install requires the installation of PyQt5 5.15.0 , which gives me this error. The odd thing is that the installation works fine for the latest version of PyQt5 (5.15.2), but this program requires 5.15.0 specifically.
命令输出:

我使用的是最新版本的 pip.关于这个问题的根本原因的任何想法?
I am on the latest version of pip. Any ideas on the root cause of this issue?
帮助我将 pip 从 20.2.3 升级到最新版本(在我的例子中是 21.1.1)
What helped me is upgrading pip from 20.2.3 to the latest one (in my case 21.1.1)
