Description
Pandas version checks
-
I have checked that this issue has not already been reported.
-
I have confirmed this bug exists on the latest version of pandas.
-
I have confirmed this bug exists on the main branch of pandas.
Reproducible Example
git clone https://github.com/pandas-dev/pandas.git
cd pandas
python3 setup.py build_ext --inplaceIssue Description
The above raises
Traceback (most recent call last):
File "/tmp/pandas/setup.py", line 666, in <module>
version=versioneer.get_version(),
File "<string>", line 1800, in get_version
File "<string>", line 1732, in get_versions
File "<string>", line 396, in get_config_from_root
File "/usr/lib/python3.9/configparser.py", line 781, in get
d = self._unify_values(section, vars)
File "/usr/lib/python3.9/configparser.py", line 1149, in _unify_values
raise NoSectionError(section) from None
configparser.NoSectionError: No section: 'versioneer'
Expected Behavior
This command has always worked, at least until April.
I have tried to understand what to do from https://github.com/python-versioneer/python-versioneer , and it says that the section is required in setup.cfg or pyproject.toml (and we have the latter). So not sure why it fails. In any case, copypasting the section also to setup.cfg and running versioneer install --no-vendor gives:
/home/nobackup/repo/pandas
creating "pandas/_version.py"
Traceback (most recent call last):
File "/home/pietro/.local/bin/versioneer", line 8, in <module>
sys.exit(main())
File "/home/pietro/.local/lib/python3.9/site-packages/versioneer.py", line 1932, in main
setup_command()
File "<string>", line 2197, in setup_command
File "<string>", line 2118, in do_setup
FileNotFoundError: [Errno 2] No such file or directory: '"pandas/_version.py"'
... which is to me even more weird - pandas/_version.py is definitely there.
I guess this might be related to #49924 , but I hadn't compiled pandas since months, so I'm not sure.
Installed Versions
Notice that the commit is wrong. I'm on 7d2337a , which however I can't compile. Also notice that versioneer is 0.28. Also notice that the bug is not tested with the last version of pandas - it's in git only. However if I don't check the box at the top it won't let me submit the issue.
