用python写脚本,一到运行就low爆,作为程序怎能没有GUI?

PyQt5环境搭建

安装环境

操作系统 Windows10 64bit
Python 3.7.0 3.8.5
PyQt5 5.15.0 5.15.2
Eric 20.9

安装Python

安装PyQt5

pip install PyQt5 -i https://pypi.douban.com/simple
pip install PyQt5-tools -i https://pypi.douban.com/simple

将pyqt5-tools安装路径添加到系统的环境变量 Path

例如: C:\Users\SKNP\Anaconda3\Lib\site-packages\pyqt5_tools

测试是否安装成功,运行以下代码

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_())

下载Eric 6: http://eric-ide.python-projects.org/eric-download.html

解压并修改文件名为eric6

在安装Eric 6之前,需要先安装Qsci模块

pip install QScintilla -i https://pypi.douban.com/simple

配置Eric 6(不推荐)

python install.py

若安装过程会出现连接超时,可尝试换源,在C:\Users\{你的用户名}\pip中新建pip.ini,输入以下内容即可,类似的也可更换其他源

[global]
index-url = http://pypi.douban.com/simple
[install]
trusted-host = pypi.douban.com

如果没有提示出错,则安装成功

安装完成后,如果eric6文件夹中没有生成eric.bat,就需要进入eric6/eric文件夹双击eric6.pyw,打开eric6

Eric 6相关配置

  • setting->preferences->Qt->Tools Directory: pyqt5_tool安装目录

  • setting->preferences->Editor->Autocompletion->QScintilla->勾选show single和Use fill-up characters

  • setting->preferences->Editor->Autocompletion->勾选Automatic Completion Enabled

  • 添加API并编译

  • setting->preferences->Project->Multiproject自定义workspace
  • 安装自动补全插件jedi
pip install jedi -i https://pypi.douban.com/simple
  • 为Eric 6安装jedi插件

接下来找到Completions,Jedi安装即可,但是插件仓库一直无法连接,这个方法对我来说不太适用,可以参考接下来的配置。

配置Pycharm+PyQt5(推荐)

参考链接:

最新版的designer.exe位置略有不同,参考:C:\Users\SKNP\anaconda3\envs\pyqt\Lib\site-packages\qt5_applications\Qt\bin\designer.exe

在pycharm中添加External Tools

  • File->Settings->Tools->External Tools->+
Name: QtDesigner
Group: External Tools
Program: C:\Users\SKNP\anaconda3\envs\pyqt\Lib\site-packages\qt5_applications\Qt\bin\designer.exe
Working directory: $FileDir$
Name: PyUIC
Group: External Tools
Program: C:\Users\SKNP\anaconda3\envs\pyqt\Scripts\pyuic5.exe
Arguments: $FileName$ -o $FileParentDir$\$FileNameWithoutExtension$.py
Working directory: $FileDir$
Name: PyRCC
Group: External Tools
Program: C:\Users\SKNP\anaconda3\envs\pyqt\Scripts\pyrcc5.exe
Arguments: $FileName$ -o$FileNameWithoutExtension$_rc.py
Working directory: $FileDir$

Done!
