Common problems and solutions to pyqt5 installation errors

With the popularity of Python, PyQt5 has become one of the preferred tools for many people to quickly develop GUI. However, installation problems are also inevitable. The following are several common problems with PyQt5 installation and their solutions.

This problem usually occurs when using pip to install PyQt5. The reason for this error is the lack of dependencies on the sip module, so you need to install the sip module manually first.

Enter the following code on the command line:

pip install sip
Copy after login

pip install PyQt5 --no-cache-dir
Copy after login
  1. The "linker command failed" error occurs during PyQt5 installation

If you encounter this problem when installing PyQt5, then you need to add -iquote (import path) to the command line, for example:

pip install PyQt5 -i https://pypi.python.org/simple/ -i and https://www.riverbankcomputing.com/static/Downloads/ PyQt5/5.5/PyQt5-5.5-gpl-Py3.4-Qt5.5.0-x32.exe -iquote “C:Python27Libsite-packagesPyQt5include”
Copy after login
  1. Some modules of PyQt5 are missing in the installation

This problem can be solved by manually installing the missing modules.

For example, if “ImportError: No module named ‘PyQt5.QtWebEngineWidgets’” appears, you need to install the PyQtWebEngine module manually. The installation method is as follows:

pip install PyQtWebEngine
Copy after login

It should be noted that if there is a serious error of missing modules, it is recommended to reinstall after deleting the installed PyQt5.

The following is a simple PyQt5 sample program:

import sys
from PyQt5.QtWidgets import QApplication, QWidget, QLabel

if __name__ == '__main__':
    app = QApplication(sys.argv)
    window = QWidget()
    window.setWindowTitle('PyQt5 Hello World')
    hello_msg = QLabel('Hello, World!', parent=window)
    window.show()
    sys.exit(app.exec_())
Copy after login
