Python IDLE 3.7.4 [重复]

Question

我下载了 Qt Designer for windows，当我运行我的应用程序时，出现此错误：

Traceback (most recent call last):
  File "C:\Users\adham\OneDrive\Desktop\test.py", line 2, in <module>
    from PyQt5.QtWidgets import QMainWindow, QApplication
ModuleNotFoundError: No module named 'PyQt5'

这是我的应用程序：

import sys
from PyQt5.QtWidgets import QMainWindow, QApplication
from PyQt5 import uic

Ui_MainWindow, QtBaseClass = uic.loadUiType('First App.ui')

class MyApp(QMainWindow):
    def __init__(self):
        super(MyApp, self).__init__()
        self.ui = Ui_MainWindow()
        self.ui.setupUi(self)
        self.ui.Button.clicked.connect(self.get_result)
    def get_result(self):
        Name=self.ui.NameEdit.value()
        Password = self.ui.PasswordEdit.value()
        self.ui.Result.setText("Name: " + Name + "\n" + "Pass: " + Password)
if __name__ == '__main__':
    app = QApplication(sys.argv)
    window = MyApp()
    window.show()
    sys.exit(app.exec_())

导师用的是python idle 3.5，我的是3.7.4，如何让设计软件和我的版本兼容？

Answer 1

python -m pip install PyQt5 应该可以工作

或者你可以尝试卸载 PyQt5 并使用python3 -m pip install *.whl
