Broken package name (since commit [754b9a52f7bb83d8d356050a14caebc6fbaccc85]) #2547

Gelma · 2022-10-20T09:14:51Z

Hi,
since commit in subject the package name is UNKNOWN. Tested on different laptops, bisected on fresh Ubuntu 22.04.

Commit 754b9a5 is part of #2523.

See #2532, I think this is a duplicate.

DimitriPapadopoulos · 2022-10-21T08:27:44Z

In short, it looks like the system package python3-setuptools is broken on Debian/Ubuntu. You need to install a vanilla setuptools, typically using pip:

sudo apt purge python3-setuptools
pip3 install -U setuptools (or pip3 install -U setuptools==59.6.0 to install the same version provided by the system package python3-setuptools)

DimitriPapadopoulos · 2022-10-21T12:01:51Z

@Gelma Does the above fix the problem?

Yet we need a different solution, because installing codespell fails both on Ubuntu 18.04 and Ubuntu 22.04.

Does the above fix the problem?

Of course, not.

My python-setuptools is not broken. Anyway, even installing the latest version via pip, the issue change, but is still broken.

I don't want to waste your precious time trying to replicate it, so I made a video starting from install of Ubuntu 22.04, trying to compile with packaged setuptools, and also after upgrading it.
There is a lot of dead time between stages, but you can skip it super quick.
Here's the video.

DimitriPapadopoulos · 2022-10-21T19:44:08Z

Indeed I cannot reproduce the problem any more today, whatever the version of setuptools:

only python3-setuptools DEB package 59.6.0-1.2 for Ubuntu 22.04
only setuptools 65.5.0 installed with pip3
both versions

Yet, I managed to fix this UNKNOWN issue somehow:

From my #2532 (comment), 5 days ago on my Ubuntu 22.04 machine:

I was convinced the version of setuptools is the root of the problem, because I was told so and I was able to fix the problem by uninstalling/installing different versions of setuptools. But obviously, there's more to it. Will keep looking.

DimitriPapadopoulos · 2022-10-21T21:05:07Z

Starting again, after uninstalling all modules installed by pip, including pip itself, and installing python-* DEB packages of required modules, including pip :

$ pip3 list --user

$

Now I can again reproduce the UNKNOWN problem:

In your case, which version of pipis available?

which pip
pip --version

Then back to your specific command:

$ python3 setup.py install --user
Traceback (most recent call last):
  File "/my/path/codespell/setup.py", line 3, in <module>
    from setuptools import setup
  File "/usr/lib/python3/dist-packages/setuptools/__init__.py", line 16, in <module>
    import setuptools.version
  File "/usr/lib/python3/dist-packages/setuptools/version.py", line 1, in <module>
    import pkg_resources
ModuleNotFoundError: No module named 'pkg_resources'
$

According to No module named pkg_resources:

This error message is caused by a missing/broken Python setuptools package.

So let's update setuptools using pip, since the system setuptools package might be broken on Ubuntu:

$ pip3 install --user -U setuptools
Requirement already satisfied: setuptools in /usr/lib/python3/dist-packages (59.6.0)
Collecting setuptools
  Using cached setuptools-65.5.0-py3-none-any.whl (1.2 MB)

$

Now it works, more or less. The setup process does find the name (no more UNKNOWN), but still fails to determine the version, so installs codespell-0.0.0:

Not sure how to fix the version for now. Perhaps stick to pip install until a better solution is found.

Not sure how to fix the version for now. Perhaps stick to pip install until a better solution is found.

It's enough to revert these file before the commit in subject and it works like a charm:

setup.py
codespell_lib/_codespell.py
codespell_lib/__init__.py

DimitriPapadopoulos · 2022-10-22T10:33:03Z

The whole point of #2523 was to migrate from the traditional setup.py to pyproject.toml, as described in PEP 621, following Configuring setuptools using pyproject.toml files. Perhaps it was too early to migrate, but I suspect the maintainers won't revert to the legacy build system.

In this context, the real solution is to understand why the name and version of the project are not properly picked by the versions of pip and setuptools bundled with Ubuntu 22.04, and ideally work around the problem in codespell, or open bug reports against Ubuntu.

And again, the proper way to install is not python setup.py install.

Gelma · 2022-10-23T10:41:24Z

Just for the record, a few notes.

In this context, the real solution is to understand why the name and version of the project are not properly picked by the versions of pip and setuptools bundled with Ubuntu 22.04, and ideally work around the problem in codespell, or open bug reports against Ubuntu.

a) did you watch my video? In that you can see that even installing the latest setuptools (not packaged, by pip), the problem change, is not fixed (the version number is picked as 0.0.0);
b) let's pretend that anyway is a Ubuntu issue, ok, here's a video with the same thing on Arch.

And again, the proper way to install is not python setup.py install.

Ok, so this is not the right way (btw, first time you tell me this). Bring us the light: which one to use?

The funny thing is every time you try to blame something else, and each time is not the solution. Let's recap:
a) my installation is broken;
b) setuptool packaged by Ubuntu is too old;
c) setuptools via pip (but you can't blame it, so is anyway related to Ubuntu);
d) now the command I use;

and now, guess what next?

You can keep it broken and blame the rest of the world. No drama. Mine is working because I reverted.
By the way, from the PEP I quote:

Backwards Compatibility
As this provides a new way to specify a project’s core metadata and is using a new table name which falls under the reserved namespace as outlined in PEP 518, there are no backwards-compatibility concerns.

DimitriPapadopoulos · 2022-10-23T13:17:58Z

I am sorry I haven't been clear enough. The proper way to install is pip install, see for example Installing Packages. The command you used, python setup.py install is a legacy command bound to disappear. Unfortunately, file setup.py, which has been kept to help with the transition, doesn't work, at least not out of the box on Debian/Ubuntu. Providing a setup.py file to help with transition, only to discover it doesn't work, is far from ideal. This is why I am trying to help with this legacy command – although it is deprecated.

I have been discovering all this myself in the last few days, because of similar issues I had while trying installing codespell. This is still new for me, so please bear with me if I am not making myself clear enough, I am still learning.

Again, the right thing to do is to use pip install, as documented in the README:

Development Setup

You can install required dependencies for development by running the following within a checkout of the codespell source:
pip install -e ".[dev]"

Nowhere does it instruct running setup.py, it's pip all over the place.

Now, this is where it gets complex, even pip install . does not work with the pip and setuptools packages shipping with Debian/Ubuntu. This is consistent with the Python Packaging User Guide and specifically the Requirements for Installing Packages:

Ensure pip, setuptools, and wheel are up to date

While pip alone is sufficient to install from pre-built binary archives, up to date copies of the setuptools and wheel projects are useful to ensure you can also install from source archives:
python3 -m pip install --upgrade pip setuptools wheel

Now back to the issues you (and I) have been experiencing:

To fix the UNKNOWN package name, both with pip install and python setup.py install, you need to upgrade pip itself.
Then to fix the No module named 'pkg_resources' error, only with python setup.py install, you need to upgrade setuptools too.
Finally, I think I have found a way to fix the wrong 0.0.0 version picked in the python setup.py install case only: you need to upgrade setuptools_scm too.

In short, the legacy installation now works for me, provided I update first:

python3 -m pip install --user --upgrade --ignore-installed pip setuptools wheel setuptools_scm
python3 setup.py install --user

But again, the standard installation process would rather be:

python3 -m pip install --user --upgrade --ignore-installed pip setuptools wheel setuptools_scm
pip install --user .

Of course, you are free to revert as you did to run the legacy python setup.py install. Alternatively, you can embrace the new Python packaging system and document these annoying pitfalls during this transition period – that's my choice.

And by the way, I am not the maintainer and I haven't made the choices you complain about. I am just trying to help on my spare time. You have been barking up the wrong tree – if barking was ever needed here.

After many tests described at the end of #2523, it appears that the requirements for installing codespell are:

setuptools>=64 or perhaps even setuptools>=61: version 59.6.0 is installed by default on Ubuntu 22.04 which partly explains why installation doesn't work out of the box
setuptools_scm[toml]>=6.2: DEB package python3-setuptools-scm is not installed by default on Ubuntu 22.04 and installing it fixes the 0.0.0 version number issue

The question remains why pip install or python setup.py install are unable to pull these required modules. Still investigating this.
