Stuck using Bundler? Browse these common issues before filing a new issue.
Certain operating systems such as macOS and Ubuntu have versions of Ruby that require elevated privileges to install gems.
ERROR: While executing gem ... (Gem::FilePermissionError) You don't have write permissions for the /Library/Ruby/Gems/2.0.0 directory.
There are multiple ways to solve this issue. You can install bundler with elevated privileges using
sudo gem install bundler
If you cannot elevate your privileges or do not want to globally install Bundler, you can use the
gem install bundler --user-install
This will install Bundler into your home directory. Note that you will need to append
~/.gem/ruby/<ruby version>/bin to your
$PATH variable to use
Please open a ticket with Heroku if you’re having trouble deploying. They have a professional support team who can help you resolve Heroku issues far better than the Bundler team can. If the problem that you are having turns out to be a bug in Bundler itself, Heroku support can get the exact details to us.
Second, check the compatibility list, and make sure that the version of Bundler that you are using works with the versions of Ruby and RubyGems that you are using. To see your versions:
# Bundler version bundle -v # Ruby version ruby -v # RubyGems version gem -v
If these instructions don’t work, or you can’t find any appropriate instructions, you can try these troubleshooting steps:
# Update to the latest version of bundler gem install bundler # Remove user-specific gems and git repos rm -rf ~/.bundle/ ~/.gem/bundler/ ~/.gems/cache/bundler/ # Remove system-wide git repos and git checkouts rm -rf $GEM_HOME/bundler/ $GEM_HOME/cache/bundler/ # Remove project-specific settings rm -rf .bundle/ # Remove project-specific cached gems and repos rm -rf vendor/cache/ # Remove the saved resolve of the Gemfile rm -rf Gemfile.lock # Uninstall the rubygems-bundler and open_gem gems rvm gemset use global # if using rvm gem uninstall rubygems-bundler open_gem # Try to install one more time bundle install
