0.5.3 Install Fails with Python 2.7

[Anti-Distinctlyminty]

I know things are supposed to be moving to Python 3, but if I try to pip install 0.5.3 with Python 2.7 I get

Collecting pyseq

Thanks for the report. Sorry this slipped through the cracks. Seems like an easy fix, but I'll need to install py27 to test it (maybe naively assumed py3 is the standard now).

Thank you @Anti-Distinctlyminty I wanted to report the same issue, it is not py26 related. It looks like some metadata were added on the package creating 0.5.3 (good) and 0.5.3.1 (one too many digit for semver)

See that extra .1 ?

I'm sure that was not intended :

@rsgalloway Would it be worth creating a new release ?

It's blocking installation, for example with a pipenv based project :

[packages]
pyseq = "==0.5.*"

On install it fails with :

[...]
ar/folders/w5/wd__d7vn6tjc0k0ktztlchs40000gn/T/pipenv-c5wv7zdw-requirements/pipenv-vvum3er4-requirement.txt (line 1)) has inconsistent version: filename has '0.5.3.1', but metadata has '0.5.3'
[pipenv.exceptions.InstallError]: ERROR: Could not find a version that satisfies the requirement pyseq==0.5.3.1
[pipenv.exceptions.InstallError]: ERROR: No matching distribution found for pyseq==0.5.3.1

We can pin in the Pipfile to 0.5.2, since 0.5.3 is not installable, but we will have to adjust on 0.5.4.

[rsgalloway]

There was a minor issue with the 0.5.3 release and pypi does not support overriding existing uploads, hence the 0.5.3.1 pypi version.

I agree, the easiest solution may be cutting a 0.5.4 release to address this and the py2.7 compatibility. Will work on that today and push an update.

pull request posted here: https://github.com/rsgalloway/pyseq/pull/65

let me know if you see any issues, otherwise will merge and push to pypi tomorrow.

[rsgalloway]

Just pushed 0.5.4 to pypi, hopefully this issue is resolved now.

https://pypi.org/project/pyseq/0.5.4/

Confirmed, thank you @rsgalloway !
