python pyqt5、pyqt5 tools安装失败

安装pyqt5失败

安装失败大概率是python版本过高，安装3.7版本python(多版本共存 )，升级pip
报错:
ERROR: Could not build wheels for sip which use PEP 517 and cannot be installed directly
升级pip

python -m pip install --upgrade pip

安装pyqt5（使用清华源安装）

pip install pyqt5 -i https://pypi.tuna.tsinghua.edu.cn/simple/

安装pyqt5-tools

pip install pyqt5-tools -i https://pypi.tuna.tsinghua.edu.cn/simple/

安装完后配置开发工具，找不到desinger.exe建议直接搜索文件

安装目录下\Python\Lib\site-packages\qt5_applications\Qt\bin
