Heroku Deploying: Failed to install gems via Bundler

Question

While trying to deploy my app to heroku, I get this error:

I have already tried bundle lock --add-platform x86_64-linux but didnt work. I have also tried to solve it with other methods, such as "bundle lock --add-platform ruby", with no success. Please help!

Answer 1

The problem I had was that I was did not added, commited and pushed. This solved the issue: ' bundle lock --add-platform x86_64-linux git add -A git commit -m 'Add platform' git push '
