[issue32295] User friendly message when invoking bdist_wheel sans wheel package

[Éric Araujo]

Éric Araujo  added the comment:

The devs probably choose to use distutils.Command as base class for maximum 
compatibility, but I suspect 99.99% of users use the setuptools integration 
(entry points 
https://github.com/pypa/wheel/blob/3a87ecebaba765475392ae2cdfa2a51cb78360e0/setup.py#L53-L54
 ) rather that distutils integration (explicit cmd_class setting in setup.py or 
--command-packages on the command line)

I’m inclined to reject the special case in distutils and encourage you to send 
the patch to setuptools (a similar PR, not option 1 or 2).

Ernest W. Durbin III  added the comment:

bdist_wheel is implemented as a distutils.core.Command, see 
https://github.com/pypa/wheel/blob/3a87ecebaba765475392ae2cdfa2a51cb78360e0/wheel/bdist_wheel.py

I was unable to find a good place to transparently hook in and catch the 
missing command class, but I agree that setuptools would be a far faster avenue 
to get this out to users.

Alternatives include:
  1) implementing bdist_wheel as a command in setuptools... which would have to 
get out of the way or call the real command when the wheel package is installed.
  2) trying to get wheel merged into setuptools, which would be a much larger 
project.

I'll see what option 1 looks like!

Éric Araujo  added the comment:

I don’t know that bdist_wheel integrates with pure distutils without 
setuptools.  I think this PR should target setuptools (it will also make it 
propagate to users faster and regardless of Python version).

[issue32295] User friendly message when invoking bdist_wheel sans wheel package

[Ernest W. Durbin III]

New submission from Ernest W. Durbin III :

Wheels are a well-known part of the Python packaging ecosystem at this point!

Many tutorials, gists, and other tools suggest to build wheels using setuptools 
and distutils, but may not remind users to install the wheel package.

In light of Issue 31634 being temporarily suspended and given that this does 
not interfere with experienced users implementing their own bdist_wheel 
command, it should be a welcome addition to help guide novice packagers in the 
right direction.

Result for a Python environment without the `wheel` package installed:

$ python3 setup.py bdist_wheel
usage: setup.py [global_opts] cmd1 [cmd1_opts] [cmd2 [cmd2_opts] ...]
   or: setup.py --help [cmd1 cmd2 ...]
   or: setup.py --help-commands
   or: setup.py cmd --help

error: invalid command 'bdist_wheel'
note: The wheel package provides this command. See 
https://packaging.python.org/tutorials/distributing-packages/#wheels for 
information on packaging wheels
