安装PyQt5
python官方源下载较慢，因此使用阿里云的国内镜像源。C:\Users\admin>pip install PyQt5 -i http://mirrors.aliyun.com/pypi/simple/ --trusted-host mirrors.aliyun.com Looking in indexes: http://mirrors.aliyun.com/pypi/simple/ Collecting PyQt5 Downloading http://mirrors.aliyun.com/pypi/packages/9e/53/9476464c2a8db5252de96fd8ff39ec5db6ef09b8a08a7152546b7f142d90/PyQt5-5.15.4-cp36.cp37.cp38.cp39-none-win_amd64.whl (6.8 MB) |████████████████████████████████| 6.8 MB 3.2 MB/s Collecting PyQt5-Qt5>=5.15 Downloading http://mirrors.aliyun.com/pypi/packages/37/97/5d3b222b924fa2ed4c2488925155cd0b03fd5d09ee1cfcf7c553c11c9f66/PyQt5_Qt5-5.15.2-py3-none-win_amd64.whl (50.1 MB) |████████████████████████████████| 50.1 MB 547 kB/s Collecting PyQt5-sip<13,>=12.8 Downloading http://mirrors.aliyun.com/pypi/packages/4b/67/4d4f176ebd76673f0701fbb8a571f1b25d6f8b9b52c3e8905a375d87b925/PyQt5_sip-12.8.1-cp38-cp38-win_amd64.whl (63 kB) |████████████████████████████████| 63 kB 686 kB/s Installing collected packages: PyQt5-sip, PyQt5-Qt5, PyQt5 Successfully installed PyQt5-5.15.4 PyQt5-Qt5-5.15.2 PyQt5-sip-12.8.1 -

添加环境变量
- 将
designer.exe目录添加到环境变量 (可在cmd中输入path确认)
- 将
不同版本designer.exe的所在路径可能不一样。安装过三次，每次都不一样，因此可以在pyqt的几个目录下找一下
designer
- 测试PyQt5环境是否安装成功
执行脚本之后弹出一个窗口(Widget)界面,则说明PyQt5环境安装成功。import sys from PyQt5 import QtWidgets, QtCore app = QtWidgets.QApplication(sys.argv) widget = QtWidgets.QWidget() widget.resize(360, 360) widget.setWindowTitle('Hello, PyQt5') widget.show() sys.exit(app.exec_())

PyQt5的依赖模块
- 在cmd中进入Python交互窗口然后输入语句
import PyQt5和help(PyQt5). - 其中的PACKAGE CONTENTS就是其依赖模块。
