wxPython 笔记
安装
Win7 / Win10
直接通过 pip install wxpython 安装
Ubuntu18.04 / Ubuntu 20.04
在Linux下的安装会稍微麻烦, 可以参考官网上的说明 https://wxpython.org/pages/downloads/
因为存在不同的环境, 以及Gtk2, Gtk3, 所以没有针对各个发行版直接可用的pip whl文件, 通过 pip install wxpython的话, 实际上会去下载源码到本地编译安装, 参考 https://wxpython.org/blog/2017-08-17-builds-for-linux-with-pip/index.html 其中What You Need部分, 在Ubuntu下需要安装这些包
# 安装依赖 sudo apt install make gcc libgtk-3-dev ibgstreamer-gl1.0-0 freeglut3 freeglut3-dev python3-gst-1.0 libglib2.0-dev ubuntu-restricted-extras libgstreamer-plugins-base1.0-dev # 从国内源下载, 之后会自动启动编译 pip3 install -i https://pypi.mirrors.ustc.edu.cn/simple/ wxpython
但是这个编译时间非常长, 在i5 2520M 下编译需要将近一个小时.
还好官方有提供Ubuntu的whl文件, 可以直接安装, 从 https://extras.wxpython.org/wxPython4/extras/linux/gtk3/ubuntu-20.04/ 直接下载20.04的whl文件, 在本地通过pip安装. 对于Ubuntu18.04存在不同的python版本, 选择不同的cp36, cp37, cp38
pip3 install -U -f wxPython-4.1.0-cp38-cp38-linux_x86_64.whl wxPython
在安装的过程中, 会检查numpy并下载安装
在后续运行代码时, 如果遇到 libSDL2-2.0.so.0: cannot open shared object file: No such file or directory 错误, 则需要安装 libsdl2-2.0-0
sudo apt install libsdl2-2.0-0
打包生成可执行文件
在Ubuntu下安装pyinstaller, 然后在项目目录下执行命令
$ pip3 install pyinstaller $ pyinstaller v2subform.py 36 INFO: PyInstaller: 3.6 36 INFO: Python: 3.6.9 36 INFO: Platform: Linux-4.15.0-99-generic-x86_64-with-Ubuntu-18.04-bionic 37 INFO: wrote /home/milton/PycharmProjects/python-tools/v2sub/v2subform.spec 38 INFO: UPX is not available. 40 INFO: Extending PYTHONPATH with paths ['/home/milton/PycharmProjects/python-tools/v2sub', '/home/milton/PycharmProjects/python-tools/v2sub'] 40 INFO: checking Analysis ... 8115 INFO: Building COLLECT COLLECT-00.toc 8803 INFO: Building COLLECT COLLECT-00.toc completed successfully.
最后生成的结果在dist目录下, 如果运行时不希望出现命令行, 可以加上 --noconsole 参数
在用下面的代码测试时, 发现生成的结果文件非常大, 有263M, 其中wx目录就占了200多M,
$ ll -h wx total 199M -rwxr-xr-x 1 milton milton 18M May 7 11:16 _adv.cpython-36m-x86_64-linux-gnu.so* -rwxr-xr-x 1 milton milton 156M May 7 11:16 _core.cpython-36m-x86_64-linux-gnu.so* -rwxr-xr-x 1 milton milton 14M May 7 11:16 _grid.cpython-36m-x86_64-linux-gnu.so* -rwxr-xr-x 1 milton milton 12M May 7 11:16 _html.cpython-36m-x86_64-linux-gnu.so* -rwxr-xr-x 1 milton milton 795K May 7 11:16 siplib.cpython-36m-x86_64-linux-gnu.so*
这么大的发布文件, 在日常和商业上都是非常不适用的, 这就仅作为一个尝试吧.
