bundle install gemspec error spree_social.gemspec - ruby-on-rails

Question

In my app when I am running bundle install, I am getting below error.
vendor/gems/spree_social/spree_social.gemspec
is not valid. Please fix this gemspec.
The validation error was 'spree_social-3.1.0.beta contains itself
(spree_social-3.1.0.beta.gem), check your files list'
I tried everything like removing the Gemlock and updating the gems. It didn't work.
Below is my Gemfile

Anyone else faced this?

This is most likely because your compiled .gem file is contained in the repository. I assume that this is because the gem is trying to package the spree_social-3.1.0.beta.gem file inside itself, and it doesn't like that. Try removing the .gem file from the repository and rerunning bundle install.
I am willing to bet that File.join(File.dirname(__FILE__), '/vendor/gems/spree_social' points to a git repository, where bundle install will compile and install the gem each time you try to run it. My understanding is that when the gem is compiled in this way, it runs git ls-files -z`.split("\x0") on the git repository to get the list of files to put in the gem. Since the .gem file appears in the results, it tries to compile it into the gem, which causes it to fail.
I ran into this issue today, where my Gemfile was pulling a gem from a repository I published to Github, and bundle install kept failing until I removed the .gem file from the repository.
