Problems installing on Windows 7

[pschloss]

I have a workshop that I'm teaching tomorrow and Wednesday and one of the learners is using Windows 7. In a problem that is pretty similar to Issue #42 from last year, we get git-bash, R, and RStudio installed, but not the SWC installer. It creates the .swc/ folder but not .bash_profile. The only thing in .swc/ is .swc/bin/nosetests. When we launch the installer it again flashes up a terminal, seems to do something with nosetest and then I see a bunch of Traceback text before the screen quickly closes. FWIW, it is a 64 bit OS and we do seem to be in the home directory. We've also uninstalled, downloaded, and installed several times now. Ideas?

Try running the installation script 1 from the command line. Then you'll have time to read the tracebacks (and paste them in here :).

This looks like #54 and #60, which we still don't have a fix for. You can work around it by installing the broken package by hand (e.g. download [1,2] and unpack them into ~.swc\opt\make). Or by hosting the sources somewhere that can be reached without TLS and replacing the installation script's current URLs with your alternate location.

Ok, thanks - is this something we should expect to be a problem for all windows users or is it a fluke?

[embray]

It will probably be a problem for many Windows users. Right now, honestly, I wouldn't put too much stock in the existing Windows installer at all, and not just for that reason.

I have a plan for redoing it but there's been slow to grow consensus on what to do. Sorry.
