Hello Flox Users !
I’ve created a new flox environment to develop ruby on rails application. I was able to find ruby package, however I’m unable to find the latest version rails 8.0 in the flox install search results. I was able to find rubyPackages.rails which installs rails version 7.2.2.1, but I was unable to find and install version 8.0.
Could someone guide me as how or where to find it ?
I’m assuming I cannot do a ‘gem install rails’ as it would install to the global .gem directories.
Thanks,
Vishnu

Hi @vishnu3014 - nice to meet you 🙂
You can use `flox show` to see all the versions available for installation. If you don’t specify the version, it installs the latest.
```auto
rtb@Robins-MacBook-Pro ~ % flox search rails
grails Full stack, web application framework for the JVM
rails-new Generate new Rails applications without having to install Ruby
rubyPackages.rails
emacsPackages.grails
vimPlugins.vim-rails
rubyPackages_2_5.rails
rubyPackages_2_6.rails
rubyPackages_2_7.rails
rubyPackages_3_0.rails
rubyPackages_3_1.rails
Showing 10 of 67 results. Use `flox search rails --all` to see the full list.
Use 'flox show ' to see available versions
rtb@Robins-MacBook-Pro ~ % flox show rubyPackages.rails
rubyPackages.rails -
rubyPackages.rails@7.2.2.1
rubyPackages.rails@8.0.2
rubyPackages.rails@7.1.3.4
rubyPackages.rails@7.1.3.2
rubyPackages.rails@7.1.3
rubyPackages.rails@7.1.2
rubyPackages.rails@7.1.0
rubyPackages.rails@7.0.8
rubyPackages.rails@7.0.7
rubyPackages.rails@7.0.6
rubyPackages.rails@7.0.5
rubyPackages.rails@7.0.4.3
rubyPackages.rails@7.0.4.2
rubyPackages.rails@7.0.3
rubyPackages.rails@7.0.2.3
rubyPackages.rails@7.0.1
rubyPackages.rails@6.1.4
rubyPackages.rails@6.1.3.2
rubyPackages.rails@6.1.0 (aarch64-linux, x86_64-darwin, x86_64-linux only)
rubyPackages.rails@4.2.11.1 (aarch64-linux, x86_64-darwin, x86_64-linux only)
```
In this case v7.2.2.1 is listed as the latest so to install v8, you would use `flox install rubyPackages.rails@8.0.2`.
Hope this helps!

Thanks @robinbrantley !
I’m able to install the latest version or rails 8.0.2 !!
It’s very interesting that instead of following the usual recommended path of performing ‘gem install rails’ to install the framework (and then updating myraid number of settings like PATH, GEM\_PATH, RUBY\_PATH etc, the system simple takes care of lot of things in the background) it’s so much cleaner to simply install a needed version and flox takes care of the dependencies ! I’ve been in very difficult situations in resolving dependencies and I honestly thought that I may hit limits of using Flox, but I’m glad I’m wrong, the Flox journey continues !!
Please convey my best to the development team !
