执行python setup.py bdist_wheel时'universal'选项报错如何修复？

Hey there, I’ve run into this exact issue before when updating my build tools—let’s get this sorted out quickly.

What’s causing this? #

The universal option under the [bdist_wheel] section in your setup.cfg is deprecated in newer versions of setuptools and wheel. The maintainers moved this setting to a dedicated [wheel] section instead, so the old configuration is no longer recognized.

Step-by-step fixes: #

1. Update your build tools first
   Outdated versions might have conflicting behaviors, so let’s make sure we’re working with the latest releases:

   pip install --upgrade setuptools wheel
   

2. Fix your setup.cfg file
   Open your setup.cfg and look for a section that looks like this:

   [bdist_wheel]
   universal = 1
   

   Replace it with this (if you still want to generate a universal wheel compatible with both Python 2 and 3):

   [wheel]
   universal = 1
   

   If you don’t need a universal wheel, you can just delete that entire [bdist_wheel] section entirely.

3. Re-run your build command
   Now try executing the command again:

   python setup.py bdist_wheel
   

   This should work without throwing the error now.

Extra note: #

If you’re using setup.py directly instead of setup.cfg, you can achieve the same universal wheel effect by adding the universal=True parameter to your setup() call:

setup(
    # ... other parameters ...
    universal=True
)
