[yt-users] Rollback to yt version 2.x problem

[Matthew Turk]

Hi Roberto,

I'm not sure what that error means, other than it can't make your
fKDtree installation work.  One workaround would be to "pip uninstall
forthon" which will prevent it from trying to compile.  Another would
be to forcibly update, which may be dangerous if you have made
modifications to the source:

hg up -C -r yt-2.x
hg purge
python2.7 setup.py develop

Stop by IRC if you want to work through this in lower-latency...

-Matt
