`make build` fails after regenerating the pypi-dependencies.json

make build ends in error:

I'm not sure how to fix that...
That's preventing me to test and submit a PR for issue #24 (I need to add paramiko to requirements.txt, regenerate the dependencies and validate with a build and run).

Thanks for pointing out this problem @Roming22. I get the same error after upgrading pypi-dependencies.json after upgrading flatpak-pip-generator. When using the old flatpak-pip-generator, I can run make generate and make build and everything works fine. I guess there must be something special about the version of flatpak-pip-generator I was using. I'm still investigating...

[Roming22]

Do you have any info on the version you are using? An md5 hash, a date the file was created? That might help me find the proper version and submit a change to Makefile.

[Roming22]

@inercia Any thing I can do to help move this issue forward? I'd love to be able to build k3x locally and submit fixes/features.

[Roming22]

I cannot reproduce with the latest version of the repository. Using a brand new VM, a clean checkout followed by make deps && make build && make run launches the application as expected.
@inercia it looks like the issue can be closed, but I'll let you do it in case there was still something you wanted to do about it.

[Roming22]

Ignore my previous comment, I forgot to try and regenerate the dependencies, which is now failing with

@Roming22, that's strange, that URL seems to be working fine:

$ curl https://pypi.org/pypi/system_hotkey/1.0.3/json
{"info":{"author":"timothy eichler","author_email":"tim_eichler@hotmail.com","bugtrack_url":null,"classifiers":["Development Status :: 4 - Beta","Intended Audience :: Developers","License :: OSI Approved :: BSD License","Operating System :: OS Independent","Programming Language :: Python :: 3"],"description":"System Hotkey...

Could that be a connectivity problem?

[Roming22]

@inercia The issue is that flatpak-pip-generator removed support for any.whl extensions, which is the extension used by system-hotkey.

system-hotkey does not seem to be very active. I would suggest you migrate to the keyboard package which seems to have a larger following, be supported, and uses the extensions supported by flatpak-pip-generator.

[Roming22]

@inercia Can you confirm that on your side the dependency generation fails if you add a new dependency to requirements.txt (e.g. paramiko)?
