I’m trying to start a rails application in IntelliJ with the Ruby plugin.

I’ve imported the application and set up the run configuration as best I can. When I try to run it I get the error:

NoMethodError: undefined method `version_requirements' for #<Gem::Dependency:0x7de21f45>

When looking for an answer I found this page saying that I should do this:

$ gem install rubygems-update -v='1.4.2'
$ gem uninstall rubygems-update -v='1.5.0'
$ update_rubygems

Since it’s IntelliJ’s ruby plugin that is managing the gems, I assume that I have to change the version of rubygems-update that the plugin is using.

Is this the right approach to take? And if so, can anyone tell me how to go about it?

I tried listing the gems but that gem is not shows so I must not be listing the gems in the right place, but I don’t know where to look.

Many thanks 🙂

    IntelliJ IDEA cannot handle it, you will need to install the appropriate rubygems version from the command line.

    Note that your current rubygems-update version may be different, verify it with gem list and use the reported version when uninstalling.
