My global and local ruby version is the same:

rbenv version

Now when i start my app with command:

bundle exec unicorn -c my_unicorn_config.rb -d

I get this in my error log:

Why bundler/runtime.rb can't load my gems? I also define my gem env vars with export GEM_HOME="${HOME}/myapp/shared/bundle/ruby/1.9.1/gems" as well as export GEM_PATH="${GEM_HOME}"

EDIT:

My bundle check output does show that all deps are satisfied:

    [myapp@myapp appuser]$ bundle check
Your Gemfile lists the gem uuidtools (>= 0) more than once.
You should probably keep only one of them.
While it's not a problem now, it could cause errors if you change the version of one of them later.
The Gemfile's dependencies are satisfied

just in case would like to use a supervisor that couples well with unicorn: immortal.run/post/run.yml – Cipolin

#17644397 – Crosswind

Mine error isn't in 'require' though, see the log "Exception `LoadError' at /home/myapp/myapp/shared/bundle/ruby/1.9.1/gems/gems/bundler-1.16.2/lib/bundler/runtime.rb:81 - cannot load such file -- haml-contrib" – Eterne

Is SQLite3 itself installed on your machine? Hint: The sqlite3 gem only the Ruby interface to SQLite3 but not SQLite3 itself? – Taffrail

Yeah it is. [root@myapp ~]# rpm -qa | grep sqlite sqlite-devel-3.6.20-1.el6_7.2.x86_64 sqlite-3.6.20-1.el6_7.2.x86_64 – Eterne

Your issue is definitely lower than haml-contrib e.g. sqlite also why sqlite3 and postgres pg? – Crosswind

app uses postgres db backend – Eterne

Can you post the unicorn configuration? – Percussive

Then what is sqlite3 for? – Crosswind

I think we need the unicorn configuration so we can reproduce the issue. Exactly as @Percussive has written. Please see stackoverflow.com/help/mcve fo rmore. – Mckoy

Answer 1

Are you sure you have all gems you need?

I have tried to install a your version of ruby the 1.9.3-p551 (via rvm). When I tried to install anything via gem it was showing the following error message:

YAML safe loading is not available. Please upgrade psych to a version that supports safe loading (>= 2.0).

I had to fix it via:

gem install psych -v 2.2.4

Your error suggests you are missing it or have an older version somewhere:

- cannot load such file -- sinatra-activerecord Exception `NameError' at /home/myapp/.rbenv/versions/1.9.3-p484/lib/ruby/1.9.1/psych/core_ext.rb:16

- undefined method `to_yaml_properties' for class `Object'

Could you try it out, installing psych correct version, if it helps you?

Note: the psych has been part of MRI ruby from 1.9.2. However, you may need a newer version, thus the gem.

i'll try to add and report back – Eterne

@DanilaLadner so what did you find out? – Mckoy

Answer 2

It doesn't find activerecord, it doesn't find sinatra-activerecord, it doesn't find haml-contrib. Are you sure you did run bundle?

If that doesn't help, my next step would be to upgrade to ruby 2.1 or 2.2, it's not that much pain.

please see my edit. I can't upgrade unfortunately, also it works fine on another host using 1.9.3 – Eterne
