Issues with install on Windows (encoding)

[MHuberFaust]

Hi,

I'm trying an install on a Windows machine as a test run and found into several problems so far: (Usually I tried to avoid Windows, so I might not be as familiar with common workarounds)

The Windows console had encoding issues:

(base) C:\Users\knutt\raiseWikibase>pip3 install .
Processing c:\users\knutt\raisewikibase
   DEPRECATION: A future pip version will change local packages to be 
built in-place without first copying to a temporary directory. We 
recommend you use --use-feature=in-tree-build to test your packages 
with this new behavior before it becomes the default.
    pip 21.3 will remove support for this functionality. You can find 
discussion regarding this at https://github.com/pypa/pip/issues/7555.

Specifying the encoding in setup.py fixed it.

I did not try it on another machine. So it might be related to this system being Windows or the lates updates.

Best,

Well, it says packaging.version.InvalidVersion: Invalid version: 'v1.35.0-wmde.0'. Could you try to change the version value in setup.py to any other value, e.g., 1.0.0? May be for some reason it just does not like the string "1.35.0-wmde.0"...

[MHuberFaust]

It probably has to do with version='1.35.0-wmde.0' not being a valid version according to PEP440

Changing the version in setup.py did not change the outcome. (already tried it)

[shigapov]

Is it the same error message after you changed the version?

[MHuberFaust]

Does it look somewhere else? Also, the error code says 'v1.35.0-wmde.0' , which suggests the former.

[MHuberFaust]

Is it the same error message after you changed the version?

the error message stays the same

[shigapov]

Try in editable mode pip install -e .

[MHuberFaust]

same error

[shigapov]

Try uninstalling

[MHuberFaust]

"Skipping RaiseWikibase as it is not installed."

Edit: I assumed you wanted me to uninstall and reinstall with pip

[shigapov]

Right, it is not yet installed obviously :)

Try pip with --use-deprecated=legacy-resolver

[MHuberFaust]

still the same

[shigapov]

May be downgrading pip to the version when PEP440 was not used? Is there a version?

[MHuberFaust]

A workaround might be downgrading to pip 21.0 as hinted here where --use-deprecated=legacy-resolver still works.

It still seems to be worth it to change the tag to an PEP440 valid version.

[shigapov]

Agree!

[shigapov]

I've changed version in setup.py to "1.35.4" according to the used Wikibase Docker image.

[MHuberFaust]

6c618bc34529cba88a2e724449626c297815a19b

in setup.py did not fix it.

I think it looks at different metadata. (maybe https://github.com/UB-Mannheim/RaiseWikibase/releases/tag/v1.35.0-wmde.0)

A workaround might be downgrading to pip 21.0 as hinted here where --use-deprecated=legacy-resolver still works.

It still seems to be worth it to change the tag to an PEP440 valid version.

did not work either and results in the same error message.

[shigapov]

I've just created a new release v1.35.4 based on the latest Wikibase Docker.

[MHuberFaust]

That did it!

For me to run it, it still needs specifying the encoding in the with-open statement.

with open("README.md", "r", encoding='utf-8') as fh:
    long_description = fh.read()

[shigapov]

Would you like to make a pull request for that?
