PyQt5(Py2.7,Py3.6)环境搭建问题

  • Python交互模式安装第三方库（2,3同时存在）：cd到2或者3文件夹，

python –m pip install ***

（Fatal error in launcher: Unable to create process using '"'）

  • PyQt5 Designer is not working: This application failed to start because no Qt platform plugin could be initialized

    1. Go to => Python38>lib>site-packages>PyQt5>Qt>plugins
    2. In plugins copy platform folder
    3. After that go to Python38>lib>site-packages>PyQt5_tools>Qt>bin
    4. paste folder here . Do copy and replace.

    This will surely work.. Now you can use designer tool go and do some fun with python..
