This doesn't seem to generate any views for any options

[edharve]

I've ran this generator a number of times with various options, and it doesn't seem to generate any views. I've left one of the repositories on my page - the 'academicessays' repo. I don't really know why this is happening, but bundler is failing to install 'nio4r' gem at first attempt. Anyone have any ideas?

[DanielKehoe]

I've run Rails Composer with the same settings as yours and have been unable to reproduce the issue. There's no problem installing the 'nio4r' gem when I run 'bundle install.'

What happens when you select the option to build the example application 'learn-rails'?

[edharve]

The 'learn'rails' build works fine.

It's very strange. I've tried with a number of different settings, and they all return an error with 'nio4r' gem and am asked to run 'bundle exec spring binstub --all'

This also happens if I try and 'devise' options,

Many thanks for any assistance.

The log file returns the following , which I am not able to understand what this means:

What OS? Should be fine on a Mac. On Windows you can have typical problems with difficulty compiling gems that require native extensions.

[edharve]

I'm using Ubuntu 17.04. I gave up using Windows as it is terrible with Rails!

[DanielKehoe]

Check to see if the 'nio4r' gem has issues on Linux.

[edharve]

It seems like it was a problem with my OS somewhere. I think possibly conflicts somewhere caused by rvm, but I have reinstalled it and using rbenv instead and all is working fine now. Thanks for the help :)
