Rails 5

Would love to see an update. Running into errors when trying to go from 4 to 5

Thanks Douglas! I was just thinking about this.

What errors are you getting (so I can focus on those first)

I followed these two guides. http://edgeguides.rubyonrails.org/upgrading_ruby_on_rails.html#upgrading-from-rails-4-2-to-rails-5-0 http://railsdiff.org/4.2.3/5.0.0.beta1

When I tried to run bundle install I got errors, so I tried removing Gemfile.lock and redoing bundle install. When I run DEBUG_RESOLVER=1 bundle install I get caught in an infinite loop, and its difficult to see the error message.

I suspect one of the gems might be giving me problems, so I'm trying to install them one by one.

@mrdougwright maybe update bundler? I know they've improved that stuff. Might be worth posting an issue there (and link here)

Appreciate the help. I managed to get bundle install working, by installing the gems in chunks. But Rails Server dies and I can't update without getting in a loop. I'll keep digging.

Hey @mrdougwright -- did you ever get past the bundle install errors? I'm looking for things that stump people for Rails 5 as we get closer to it being released.

[mrdougwright]

No I didn't, but I haven't tried since Jan.

Hi all, currently I also try to find the best way to upgrade rails app from 4.2 to 5.2. The most critical upgrade is to move Ruby from 2.3 to 2.5 due to 2.3 EOL announcement last month. I got suggestion to upgrade Ruby first before trying to upgrade Rails but I found the resource are quite limited. I hope some of you here can help. Also I don't know if any of you running into non-support gems. What would be your suggestion to tackle. Thank you!
