Can't install - ActiveSupport::Reloader

[lhtdesignde]

Getting this error. Not sure where to look to fix this.
$ rails g react:install
/Users/stefanie/.rbenv/versions/2.2.4/lib/ruby/gems/2.2.0/gems/react-rails-1.7.1/lib/react/rails/railtie.rb:89:in block in <class:Railtie>: uninitialized constant ActiveSupport::Reloader (NameError) from /Users/stefanie/.rbenv/versions/2.2.4/lib/ruby/gems/2.2.0/gems/activesupport-5.0.0.beta3/lib/active_support/lazy_load_hooks.rb:36:in call

Hi, sorry about that!

That code was just changed to support Rails 5: #526

Judging by the stack trace, this is a Rails 5-beta3 project, correct?

If it isn't, you could try bundle exec rails g react:install -- that way it will use the Rails version from your gemfile, in case it doesn't match the default version in your terminal.

If it still doesn't work, have no fear. The install task does very little. It creates 1 empty file and adds three lines to application.js, you read the details at the bottom of this section of the readme: https://github.com/reactjs/react-rails#installation

Does any of that help!?

[lhtdesignde]

hey, thanks for the help. yes it's a rails 5 beta. I'll try to do the little stuff then manually and go from there.

[lhtdesignde]

Hey, I just installed it manually but now when actually running it, I hit the same error.

Exiting react-rails-1.7.1/lib/react/rails/railtie.rb:89:inblock in class:Railtie': uninitialized constant ActiveSupport::Reloader (NameError)`

any ideas? do I need to install some other gems?

[rmosolgo]

I'm afraid our change to support Rails 5 may have broken it! I wonder why CI doesn't fail.

Could you share:

• The full stack trace from that error
• Gemfile.lock

[rmosolgo]

In the meantime, you could try version 1.7.0, it doesn't have the to_prepare changes

[lhtdesignde]

Here you go. We are using webrick and vagrant so paths are a bit different. But stil error should be the same. Thanks I will try the older version then.
