1.下载Python
- 首先去Python官网下载需要的版本,官网连接:https://www.python.org/
小插曲:
具体下载哪个版本,我踩了好多坑,此处分享一下踩坑经历。本人电脑安装的是Qt5.12.3。由于没接触过python,因此第一次去官网下载,肯定下载最新的。安装完成之后,又去Qt官网下载PySide2xxx,但是怎么安装都是失败,经过不断的踩坑,推荐一种下载方式。具体如下:
首先去qt官网,查看你要下载的PySide2对应的Python版本,连接:
清华大学开源软件镜像站https://mirrors.tuna.tsinghua.edu.cn/qt/official_releases/QtForPython/pyside2/
然后搜索你对应的Qt版本:
由上图可以看出,我需要下载pythone的版本为35~37,因此我下载pythone37.
2.安装Python
2.1双击安装文件
Customize installation:自定义 安装
install launcher for all users:安装 启动器 给所有的用户
Add Python 3.7 to Path: 添加Python到Path环境变量中(勾选)
2.2 Optional features

tcl/tk and IDLE:python界面操作
Python test suite:python 测试环境
Py lanucher :python启动器

每个都默认勾选
2.3.高级选项
Install for all users :勾选 给所有用户
Associate files with python:关联python文件
create shortcuts for installed applications:给安装的软件,添加个快捷方式
add python to enviroment variables:将python添加到环境变量中
Precompile standard library:预编译[准备]python标准文件
Customize install location:本地安装位置
最后两个选项不需要勾选,其余的都勾选。
然后就可以点击安装了。
2.4.验证安装
验证方式如下:
C:\Users\lsyai\Desktop>pip -V
pip 19.2.3 from d:\program files\python\python37\lib\site-packages\pip (python 3.7)
C:\Users\lsyai\Desktop>python
Python 3.7.7 (tags/v3.7.7:d7c567b08f, Mar 10 2020, 10:41:24) [MSC v.1900 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> print ("hello world")
hello world
2.5.安装PySide2-xxx
C:\Users\lsyai\Desktop>pip install PySide2-5.12.3-5.12.3-cp35.cp36.cp37-none-win_amd64.whl
Processing c:\users\lsyai\desktop\pyside2-5.12.3-5.12.3-cp35.cp36.cp37-none-win_amd64.whl

验证PySide2-xxx是否安装成功
新建如下文件:test.py
import sys
import random
from PySide2.QtWidgets import (QApplication, QLabel, QPushButton,
QVBoxLayout, QWidget)
from PySide2.QtCore import Slot, Qt
class MyWidget(QWidget):
def __init__(self):
QWidget.__init__(self)
self.hello = ["Hallo Welt", "你好,世界", "Hei maailma",
"Hola Mundo", "Привет мир"]
self.button = QPushButton("Click me!")
self.text = QLabel("Hello World")
self.text.setAlignment(Qt.AlignCenter)
self.layout = QVBoxLayout()
self.layout.addWidget(self.text)
self.layout.addWidget(self.button)
self.setLayout(self.layout)
# Connecting the signal
self.button.clicked.connect(self.magic)
@Slot()
def magic(self):
self.text.setText(random.choice(self.hello))
if __name__ == "__main__":
app = QApplication(sys.argv)
widget = MyWidget()
widget.resize(800, 600)
widget.show()
sys.exit(app.exec_())
运行:
C:\Users\lsyai\Desktop>python test.py
结果:
3.配置Qt Creator(Win10下)
3.1 帮助>关于插件>选中LanguageClient插件
关闭QtCreator并再次打开。
3.2 工具>选项>切换到Language Client选项卡,点击Add按钮
3.3.使用Qtcreator新建一个pythone工程并运行
开启学pythoneQt之路。
