Python - Mac下PyQt5环境搭建

一直想写一些桌面软件,公司电脑是Ubuntu,个人电脑是Mac,Windows又是用户量最多的,想来想去使用跨平台的开发工具来写才是唯一的选择。

最终选择使用PyQt,把Python的便利和Qt的兼容完美结合。

所需软件:

  1. Python3
  2. Qt5
  3. SIP
  4. PyQt5

安装 Python3

1
brew install python3

Python环境搭建相关可参考:Python - Mac的环境搭建

安装 Qt5.5

官网下载后打开安装后,把bin目录加入环境变量

终端安装 Pyqt

Mac上使用编译安装,后面使用pyinstaller打包会出问题,推荐使用命令行一键安装,Linux如果包管理没有的话,就使用编译安装吧。

1
brew install pyqt5

编译安装 Pyqt

安装 SIP

$ python3 configure.py
This is SIP 4.17 for Python 3.5.1 on darwin.
The SIP code generator will be installed in
/usr/local/Cellar/python3/3.5.1/Frameworks/Python.framework/Versions/3.5/bin.
The sip module will be installed in
/usr/local/Cellar/python3/3.5.1/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages.
The sip.h header file will be installed in
/usr/local/Cellar/python3/3.5.1/Frameworks/Python.framework/Versions/3.5/include/python3.5m.
The default directory to install .sip files in is
/usr/local/Cellar/python3/3.5.1/Frameworks/Python.framework/Versions/3.5/share/sip.

最终安装在/usr/local/Cellar/python3/3.5.1/Frameworks/Python.framework/Versions/3.5/bin/sip,记住这个地址,安装PyQt5会用到。

安装 PyQt5

# -q 为 Qt 的 qmake 路径
# -d 为 python3.5 的 site-packages,可通过 import site; site.getsitepackages() 来查看
# --sip 为 sip 的路径
$ make
# 时间比较长
$ sudo make install

可能出现的错误:fatal error: 'qgeolocation.h' file not found
下载‘qgeolocation.h’放入PyQt-gpl-5.5.1/QtPositioning/即可

sys.exit(app.exec_())

python3 hello.py

完美运行,成功搭建好开发环境,Ubuntu的搭建和Mac类似,Windows下载PyQt5的Binary Packages一键就可以搭建好。

enjoy it~
