解决This application failed to start because no Qt platform plugin could be initialized问题
解决This application failed to start because no Qt platform plugin could be initialized问题
先贴测试代码:
from PyQt5.QtWidgets import QWidget, QApplication if __name__ == '__main__': app = QApplication(sys.argv) w = QWidget() w.show() w.setWindowTitle("Hello PyQt5") sys.exit(app.exec_())
添加系统环境变量:QT_QPA_PLATFORM_PLUGIN_PATH
路径:D:\软件\python\Lib\site-packages\PyQt5\Qt5\plugins
(即是python安装的位置)
网上也有Qt\plugins的,但是可能是因为版本原因,我的Qt下没有这个文件夹
添加后重启PyCharm即可!!!!!!!!!!!!!!!!!!!
随便用
