問題描述
我嘗試安裝的程序需要安裝 PyQt5 5.15.0 ，這給了我這個錯誤.奇怪的是，最新版本的 PyQt5 (5.15.2) 可以正常安裝，但是這個程序特別需要 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.
命令輸出:
