Question

I have strange old buggy project on Rails 2.
It have gem’s dependencies in config/environment.rb like

config.gem "andand"
config.gem "json"
config.gem "chronic"
config.gem "mini_fb"

all those gems are located in vendor/gems/

andand-1.3.3/
chronic-0.6.7/
json-1.7.3/
mini_fb-1.1.7/
rbet-1.0.3/
redis-3.0.1/
responsys_client-0.0.1/

but when i start unicorn server with this app it always complain that it can’t find this gems. Why?

UPDATE

After building and installing gem from vendor/gems rails still complain about it.

I have tweake mini_fb gem into custom mini_fb_custom gem. Changed all references in gemspec and other files from mini_fb to mini_fb_my, installed it and it is shown in gem list as mini_fb_my. But it fails to load from config/environment.rb and complains that

Missing these required gems:
  mini_fb_my  >= 0

maybe i should rename lib/mini_fb.rb to lib/mini_fb_my.rb
i’ll check it.

UPDATE 2
Yes, renaming files rocks!

Answer 1

You still need to install them from those folders, or unicorn will not know where to look for them.

Just install the gems from that directory and unicorn should pick them up.

UPDATE

You can install your gems locally with this command

gem install --local vendor/gems/gem/gem-name.gem

On more recent versions of rails you just specify path on the Gemfile

gem "gem-name", path: "path/to/gem"
