`pycatch22 0.4.4` installation fails on windows systems

[fkiraly]

Today's release 0.4.4 seems to break the ability to install pycatch22 on windows systems, see here:

https://github.com/sktime/sktime/issues/5435

Bug report from sktime:

---

We are experiencing failures from pycatch22 install, likely related to the 0.4.4 release on Oct 16 (today).

This happens on all windows systems, but not mac and unix, at attempted install of pycatch22 0.4.4. Error log:

quick question - is 0.4.5 meaning to fix this?

[fkiraly]

I can confirm 0.4.5 does not fix this.

[alex-bronia]

Is there going to be a release with this fix?

[jmoo2880]

@alex-bronia We have released a new version of pycatch22 (v0.4.5) with this fix.
