下载PyQt5
pip install PyQt5 -i https://pypi.tuna.tsinghua.edu.cn/simple
pip install PyQt5-tools -i https://pypi.tuna.tsinghua.edu.cn/simple
如果PY版本高于3.9以上,PYQt5-tools安装不了,可以安装PyQt5Designer。
pip install PyQt5Designer -i https://pypi.tuna.tsinghua.edu.cn/simple
安装成功,Designer.exe的路径是:
“python安装目录Libsite-packagesQtDesigner”下。
