yo jekyllrb not working

[githubutilities]

I install generator-jekyllrb, run yo jekyllrb and I got this error. I think it got a bug in it.

I can see the same behavior :(

I'm having the same issues (or at least similar issues) in using yo jekyllrb to initialize a directory.

I'm setting up a new machine and trying to get this generator to work but am getting similar errors thrown by "rx.js".

I've tried this with various combinations of Ruby versions and Node versions by using rvm and nvm. I've tried Ruby versions 2.1.4 and 2.2.0. I've tried npm versions 0.10.36 and 0.12.0.

In all cases I'm getting the following error. Unfortunately in reading these errors I'm confused about where the problem might be.

Here's a look at the environment that created this error message above.

Any suggestions?

[johnfmorton]

Ok, upon more investigation, I've noticed I get the above error "Cannot read property 'name' of undefined" only when I don't pick one of the 2 template options. If I leave it to pick the default for me, this error occurs. This makes me think the error I had and the ones mentioned earlier here are not the same error.

[egermano]

I've got the same error, but I didn't installed a Jekyll in my environment.

I just ran gem install jekyll before yo jekyllrb and works.

[johnfmorton]

I've tried uninstalling my global jekyll with sudo rmwhich jekyll` which did uninstall it.

I then installed again while in the directory I was trying to build into using gem install jekyll before yo jekyllrb like you've suggested. No dice on my end. Still producing the same errors for me. :-/

This issue appears to be solved with baf6f23, however this fix hasn't been published to npm, yet. Hence installing with npm install -g generator-jekyllrb will result in above mentioned error while using the GitHub version directly will work just fine.
