问题复现：
ERROR: After October 2020 you may experience errors when installing or updating packages. This is because pip will change the way that it resolves dependency conflicts.
We recommend you use --use-feature=2020-resolver to test your packages with the new resolver before it becomes the default.
qt5-tools 5.15.2.1.2 requires click~=7.0, but you'll have click 8.0.1 which is incompatible.
原因：
pip安装版本的依赖问题
解决：
pip的提示已经明确表示
在安装命令后添加 --use-feature=2020-resolver
例如：
pip install PyQt6-tools -i https://pypi.douban.com/simple --use-feature=2020-resolver
