Having the same error on OSX.

[dunovank]

Can anyone weigh in on if this has been fixed in 0.10.1?

[hainm]

if this has been fixed in 0.10.1?

Nope.

[dunovank]

Can you post the traceback for the 10.1 error

[hainm]

here we go: osx + py35

The recent versions use lesscpy to compile a series of less files into a giant css file that gets saved to your jupyter config dir. Unfortunately lesscpy requires 2.6, 2.7, or 3.3 and conda only supports 2.7, 3.4 and 3.5. When I have time I'll look into a workaround but for the time being it looks like I'll have to remove 3 compatibility. Sorry for any hassle this has caused.

[hainm]

@dunovank how's about distribute the compiled file too? I don't see why jupyter-themes needs lesscpy for end-user.

[dunovank]

That will limit the layout, font settings, etc that are able to be set using the CL but I could include a compiled css file for each theme using the default settings so that 3.4 & 3.5 users could still install them.

I'm sure there are clever ways of maintaining the flexibility without using less but I'm frankly not that experienced with css and this makes adding new features vastly simpler. That said, I'm inclined to search for a compiling workaround before I give up on this approach.

Does that sound reasonable? If so, I'll try to release a patch soon with conditional installs if executed in a 3.4 or 3.5 env so that each theme can be installed by copying/pasting from a defaults folder.

agree.

this would be great. thanks.

[mheilman]

fwiw, it looks like this is only an issue with python 3.5. I just tried in 3.4 and didn't get this error. Also, lesscpy's setup.py file says it supports 3.4, though it's README doesn't at the moment.

[mheilman]

fyi, I made a PR that may fix the upstream issue: https://github.com/lesscpy/lesscpy/pull/86

[dunovank]

Awesome, thank you! I'm currently in the process of moving and dont have
internet accesss in my new place yet so I won't be able to look into
anything for a day or two. Very much appreciate all the
feedback/contributions from everyone though.

Attempted a workaround for 3.5 users in latest release (v0.10.2). Also added a note to the bottom of the readme about the issue.

[dunovank]

marking as closed, keeping an eye on lesscpy pypi repo for 3.5 compatibility (git develop branch hasn't been officially released yet. I opened an issue, still waiting on a reply)
