This error could occur for people who installed GSAS-II with the new 
single-download windows installer, but it did not happen for me there when I 
tried it earlier today.

The fix on Windows would be to repeat the 2nd part (Install GSAS-II,
 of the instructions in place of what is below. This will update GSAS-II if 
already installed.

Yes, this is a bug! I have fixed it in the latest version of GSAS-II (#2337).

Since you need to get this update to fix updating, you need to use the command 
line (in terminal) to download it. (Yes, you could just reinstall).

1) find the directory where you installed the g2conda distribution (usually in 
your home directory) with finder
2) open a terminal window (Applications/Utilities)
3) type “cd " (note the space at the end) — do not press enter
4) drag the g2conda to the terminal window (a string like 
/Users/<yourname>/g2conda will appear)
5) press enter
6) type “bin/python GSASII/” and press enter
7) press enter (or enter a proxy address, as before) to upgrade.

Hi there,

I downloaded GSAS-2 this morning on Mac (OS X El Capitan) using the "single 
step installer", and didn't recieve any errors.  I then tried to check for 
updates (which I realize shouldn't exist yet because I probably have the most 
recent version) and got an error which may be interesting to you? See attached
