Python搭建PyQt5

软件环境搭建的问题

使用的python3.5

PyQt5官方网站

https://riverbankcomputing.com/software/pyqt/download5

      Binary Packages

      Wheels are provided for Python v3.5 and later for 64-bit Linux, OS X and 32-bit and 64-bit Windows. These include everything             needed for PyQt5 development except for Python itself.

     So long as you are using a supported version of Python you can install PyQt5 from PyPi by running: 

    pip3 install PyQt5

在cmd下运行 

    pip3 install PyQt5

报错timeout

   raise ReadTimeoutError(self._pool, None, 'Read timed out.')ReadTimeoutError: HTTPSConnectionPool(host='pypi.python.org', port=443): Read timed out.

解决问题如下：

      pip3 install --index-url https://pypi.douban.com/simple PyQt5

测试PyQt

测试程序

import sys  
from PyQt5 import QtWidgets  
app = QtWidgets.QApplication(sys.argv)  
widget = QtWidgets.QWidget()  
widget.resize(360, 360)  
widget.setWindowTitle("Hello, PyQt5!")  
widget.show()  
sys.exit(app.exec_())  

raceback (most recent call last):
  File "C:/Users/admin/AppData/Local/Programs/Python/Python35/test.py", line 2, in <module>
    from PyQt5.QtWidgets import *
ImportError: DLL load failed: 找不到指定的模块。

sip is packaged as a separate wheel which will be downloaded and installed automatically.

pip3 install --index-url https://pypi.douban.com/simple sip
