When installing a new Ruby version with
rbenv, the new versions won’t generally have appropriates gems to go with. However Trying to install the appropriate gems seems to work at first but when trying to invoke said gem, it often results in the following error (for example with
rbenv: bundle: command not found The `bundle' command exists in these Ruby versions: 3.0.2
The following commands seems to fix things, although not always it seems:
gem update --system
Throwing in a
rbenv rehash after installing the gem does not hurt as well.
