Could not bundle install because of 'eventmachine 1.0.3'

Question

$ bundle install

Errno::ENOENT: No such file or directory @ rb_sysopen - /Users/Sean/.rbenv/versions/2.1.0/lib/ruby/gems/2.1.0/gems/eventmachine-1.0.3/ext/gem_make.out

An error occurred while installing eventmachine (1.0.3), and Bundler cannot
continue.
Make sure that `gem install eventmachine -v '1.0.3'` succeeds before bundling.

$ gem list

eventmachine (1.0.3 x86-mingw32)

$ gem build eventmachine -v 1.0.3

ERROR:  While executing gem ... (Gem::CommandLineError)
Too many gem names (eventmachine, 1.0.3); please specify only one

Check you `Gemfile` if there are more than once `gem eventmachine` define. — dddd1919, Sep 25 '14 at 00:21

Try to edit Gemfile.lock and change eventmachive version from 1.0.3 to 1.0.4. This works for me.

@Andrey but how we can handle in production there we should not edit the gemlock file – yaswant singh Nov 13 '15 at 06:43
@yaswantsingh : you can remove `Gemfile.lock` and then run `bundle install` this works fine for me – Gagan Gami Mar 15 '16 at 11:42

Thank you, this worked even in 2021 when I was trying to fix someone's very old app. – Ryan Kopf Jan 26 '21 at 02:47
