What does work though

• conda install flexx -c conda-forge on Windows 7 with Python 3.6
• conda install flexx -c bokeh on Red Hat Enterprise Linux with Python 3.6

both install without any problems

Error seems similar to the ones in #7549

@kalefranz these packages have not been touched in years, can you shed some light?

[bryevdv]

@almarklein are flexx conda packages currently maintained anywhere else? Id love to remove the ones on the bokeh channel entirely.

[bryevdv]

Actually I just noticed the comment at the end. These are on conda forge now? I will just remove the bokeh channel versions and update the docs

[almarklein]

Yes, Flexx is on conda forge. The last release has been a while, I (finally) expect a new release in a few weeks.

Talking of which ... Most parts of Flexx will be py3k only in the next release. Fortunately, I managed to keep Pyscript (the bit that Bokeh uses) working on Python 2.7. It is also likely that I spin Pyscript out of Flexx, which should make things even easier for Bokeh users. I'll ping you when I have updates on that.

I will just remove the bokeh channel versions and update the docs.

That would be for the best.

[bryevdv]

I've removed the package from the channel. I will leave the issue open to update any docs.

Most parts of Flexx will be py3k only in the next release.

As long a the old releases are still available that seems fine, tho happy to update Bokeh to import smaller pyscript when that's an option
