如何抑制pyinstaller生成的可执行文件窗口中的所有警告 [英] How to suppress all warnings in window of executable file generated by pyinstaller

问题描述

我已经使用pyinstaller从python文件生成了可执行文件.该程序可以正常工作，但是在我要隐藏的窗口中显示了此警告消息.

I have generated an executable file from a python file using pyinstaller. The program works how it is supposed to work but there is this warning message it appears in the window that I would like to hide.

当在IDE中运行python文件时，以下行不会显示所有警告消息.

The following line does suppress all warning messages when the python file is run within the IDE.

warnings.filterwarnings('ignore')

但是在可执行文件的窗口中，却显示了这个警告:

But in the window of the executable file, this warning is displayed:

\venv\lib\site-packages\PyInstaller\loader\pyimod03_importers.py:627: MatplotlibDeprecationWarning:
The MATPLOTLIBDATA environment variable was deprecated in Matplotlib 3.1 and will be removed in 3.3.
  exec(bytecode, module.__dict__)

推荐答案

如果要使用自定义的 spec 构建文件，则只需将以下行添加到 spec 文件以禁止这些启动警告(根据

If you are going to using a customized spec building file, you can just add following line to your spec files to suppress these startup warnings(according to https://pyinstaller.readthedocs.io/en/stable/spec-files.html#giving-run-time-python-options):

exe = EXE(pyz,
      a.scripts,
      [('W ignore', None, 'OPTION')],
      # ...

因为 spec 文件实际上是一个 python 脚本，你可以用 os.getcwd() 替换 pathex 并确保你已经已经在 spec 文件中导入 os 模块.

Since a spec file is actually a python script, you can replace pathex with os.getcwd() and make sure you've already import os module in your spec file.

我在Windows 10 和 Python 3.7.4 和 pyinstaller 3.5 上进行了尝试.可行！

I've tried on Windows 10 with Python 3.7.4 and pyinstaller 3.5. It works!

由于您提供了自定义的 spec 文件，因此基本的构建命令应更改为:

Since you've provided a customized spec file, your basic building command should change to:

pyinstaller xxx.spec

请告诉我它是否有效.
