Could not find builder-3.0.0 in any of the sources (Bundler::GemNotFound)

Question

I've been using on my server Redmine 1.1.x for some time and I'm trying to upgrade it to 2.2.2. I followed the upgrade sequence and now the application is not working anymore :

'block in materialize': Could not find builder-3.0.0 in any of the sources (Bundler::GemNotFound)

However:

Your bundle is complete! Use `bundle show [gemname]` to see where a bundled gem is installed.
bicou@ssh:~/redmine-2.2.2$ bundle show builder
/home/bicou/gems/gems/builder-3.0.0
bicou@ssh:~/redmine-2.2.2$ env | grep gem
GEM_HOME=/home/bicou/gems/
PATH=/home/bicou/gems/bin:/usr/local/bin:/usr/bin:/bin:/usr/bin/X11:/usr/games
GEM_PATH=/home/bicou/gems/

As you can see, builder v3.0.0 is installed. What gives?

What I did try:

• remove Gemfile.lock and run bundle install again
• what Paulo Fidalgo advised (see below)

Based on Paulo Fidalgo advice:

My Gemfile contains builder 3.0.0:

bicou@ssh:~/redmine-2.2.2$ grep builder Gemfile
gem "builder", "3.0.0"
bicou@ssh:~/redmine-2.2.2$ bundle update

Your bundle is updated! Use `bundle show [gemname]` to see where a bundled gem is installed.
bicou@ssh:~/redmine-2.2.2$

Answer 1

You need to add builder to your Gemfile and then run:

bundle update

Answer 2

I had several issues (for example some gems compiled with a different ruby version than the runtime), but the main one was that my web host requires me to install gems into ~/gems and hence to export GEMS_PATH = ~/gems/ !

That, in my public/.htaccess , fixed the main issue:

SetEnv GEM_PATH /home/bicou/gems/
