How to solve rails s error Gem::MissingSpecVersionError problem?

Question

I am getting the error below when trying to run the application, so not sure how to solve it.

$ rails s

try with sudo. this will be a quick solution. but a better approach would be keeping system ruby clean. thus, you need to install rvm or rbenv. then install desired ruby version, gems etc. https://rvm.io/rvm/install — marmeladze, Jul 21 '21 at 17:56
That looks like ruby installed via homebrew rather than system ruby (which is 2.6.3), but agree w/the suggestion you install rvm or rbenv, which you can do via homebrew. In addition to managing multiple versions, they store your gems under your user directory so do `sudo` access is required. — rmlockerd, Jul 21 '21 at 18:13
I am working on a mac so it already had the ruby installed. I also have the rvm 1.29.10 (latest)installed. — J. Viégas, Jul 22 '21 at 13:11

Just had the same issue, I deleted the Gemfile.lock and installed the bundle.

rm Gemfile.lock
bundle install

I've ended up elaborating the following scheme to work around this ugly error (message):

gem list // you got local gems List  *** LOCAL GEMS ***

Now

 gem install bundler

Once bundler install start install new added bundlers

bundle install

Now all done and working just install your pod. Pod install time error solved

pod install
