Rails Heroku deployment fails: Could not find gems, Failed to install gems via Bundler

So I have a Rails application that I am trying to push to Heroku. When I run git push heroku master, I get:

$ git push heroku master

I have tried the solutions found on this question, but nothing works (I get the same error). Everything runs fine on my local machine, so I don't know why it is not working on Heroku.

I do also want to ask: Are you supposed to run the commands found on this question from your local server, or from the heroku shell for your app? Because I have tried running the commands from the heroku shell but to no avail:

$ heroku run bash --app *****
Running bash on ⬢ *****... up, run.4316 (Basic)
~ $ bundle install
bash: bundle: command not found

RUBY VERSION
   ruby 3.2.2p53

BUNDLED WITH
   2.5.14

Note: I have tried adding the x86_64-linux under platforms in my gemfile.lock, then running bundle install, then git push heroku master, and it still did not work.

I also tried replacing BUNDLED WITH in my Gemfile.lock with:

BUNDLED WITH
   2.3.25

and committing and pushing but still the same issue.

Solution

  • When deploying a Ruby on Rails on Heroku and getting an error message from Bundler that is telling it Could not find <list of gem> in cached gems or installed locally, then this might be caused by various reasons:

    1. A vendor/cache folder in the application's repository

      When there is a vendor/cache folder in the application's repository, then Bundler will try installing gem from that repository. If the repository is empty, missing gems or only include gems that were installed on a different platform, then it will fail.

      To fix this, try deleting the cache subfolder in vendor before deploying.

    2. Bundler not configured to install gems for the platform used on Heroku.

      Quote from the Heroku documentation about using Bundler:

      An app’s Gemfile.lock that is generated with Bundler 2.2.3 locally may not work on Heroku unless the Linux platform is explicitly “locked”:

      $ bundle lock --add-platform ruby
$ bundle lock --add-platform x86_64-linux
$ bundle install
$ git add . ; git commit -m "Bundler fix"

      Adding missing platform with bundle lock --add-platform x86_64-linux, running bundle install again, and then committing the changes to git and pushing to Heroku might fix the issue.
