The following error

You have already activated strscan 3.0.1, but your Gemfile requires strscan 3.0.3.  
Since strscan is a default gem, you can either remove your dependency on it or try updating to a newer version of bundler that supports strscan as a default gem. (Gem::LoadError)

where bundle -v Bundler version 2.3.13

regards a dependency which is not directly invoked in the Gemfile. The Gemfile.lock does state strscan (3.0.3) strscan is invoked by net-imap (0.2.3)

gem update --system
gem update bundler
touch tmp/restart.txt

does not solve the issue.

How can this versioning matter be ironed out? Be it via explicit verisoning or removal of dependency

CodePudding user response：

Just use this command on your SSH server

gem update strscan

to check current strscan version use

gem list | grep strscan

CodePudding user response：

Pretty much have to monkey patch the gemfile.lock to use 3.0.0 instead! https://openbuildservice.org/2022/05/11/post-mortem/
