Thanks, Kacper & Nathan --
UnsatisfiableError: The following specifications were found to be in
conflict:
- cyglfw3 -> python 3.5* -> openssl 1.0.1*
- cyglfw3 -> python 3.5* -> xz 5.0.5
- python 3.6*
Use "conda info <package>" to see the dependencies for each package.
'conda info cyglfw3' finds the package missing from linux-64 channels.
>From the unsatisfiable error, i don't really understand the best course of
action. It would seem at this point that cyglfw3 has bindings for
python3.5, but not yet for python3.6 -- is that the upshot?
I don't know what's required to generate the updated bindings. The 'yt'
install was done using this same procedure:
conda install -c http://use.yt/with-conda yt
The versions are openssl is 1.0.2, and xz 5.2.2-1
Thanks,
~ E.m
