I cloned the repository with git (per step 1) and installed anaconda (per step 2a), but the environment check came up with a number of omissions and outdated versions. I copy the message below.

What is the difference between "lecture" and "interactive"? Aren't all notebooks interactive? Should I move my intro notebooks from "lecture" to "interactive"?

This is a recent and reported issue on their gitter channel

I have a Mac, have not previously installed Anaconda, and have successfully downloaded the shell installer for it in step 2a of the Installation and Setup instructions. My question is how precisely do I run the shell installer? Thanks.

Hi --
I have not been able to install properly four packages:
scipy, skimage, specviz, and stginga

This is what my terminal shows when I try to run the check_env.py:
"(aas229-workshop) C:\aas229_workshop>python check_env.py
Found photutils 0.3
Found matplotlib 1.5.3
Error: Failed import: No module named 'scipy'
Found numpy 1.11.2
Error: Failed import: No module named 'skimage'
Found astropy 1.3
Found pandas 0.19.2
Error: Failed import: No module named 'specviz'
Error: Failed import: No module named 'stginga'
Found gwcs 0.7
Found ginga 2.6.1
Found astroquery 0.3.4
Found glue 0.11.1
Found IPython 5.1.0
Found notebook 4.3.1"

When I try using pip install to download these four, I get this error:
"Could not find a version that satisfies the requirement skimage (from versions: )
No matching distribution found for skimage"

I've read about issues regarding downloading scipy for windows, is this one of the issues? Thanks!

Installed with steps 1 and 2b with no errors, but when I run check_env.py I get one error:

Error: stginga version 0.1.3 or later is required, you have version 0.1.2.dev197

How do I install the newer version of stginga?
