grep not finding ruby version

[colin-byrne-1]

Hey,

So tasks are failing on a grep of the rbenv versions, and can't seem to find 2.2.2, my desired version. Of course '2.2.2' shows up in the version list so this doesn't make much sense. I got these first on a system install, then on a user install:

TASK: [zzet.rbenv | check ruby {{ rbenv.ruby_version }} installed for system] *** 

failed: [ansible] => {"changed": false, "cmd": "$SHELL -lc \"rbenv versions | grep 2.2.2\"", "delta": "0:00:00.071108", "end": "2015-12-29 19:19:48.077976", "rc": 1, "start": "2015-12-29 19:19:48.006868", "stdout_lines": [], "warnings": []}
...ignoring

also thrown on:

TASK: [zzet.rbenv | install ruby {{ rbenv.ruby_version }} for select users] *** 

failed: [ansible] => (item=[{u'cmd': u'$SHELL -lc "rbenv versions | grep 2.2.2"', u'end': u'2015-12-29 19:35:57.621104', u'stderr': u'', u'stdout': u'', u'changed': False, u'rc': 1, 'item': 'deploy', u'warnings': [], u'delta': u'0:00:00.073502', 'invocation': {'module_name': u'shell', 'module_complex_args': {}, 'module_args': u'$SHELL -lc "rbenv versions | grep 2.2.2"'}, 'stdout_lines': [], u'start': u'2015-12-29 19:35:57.547602'}, 'deploy']) => {"changed": true, "cmd": "$SHELL -lc \"rbenv install 2.2.2\"", "delta": "0:00:00.083065", "end": "2015-12-29 19:35:58.340299", "item": [{"changed": false, "cmd": "$SHELL -lc \"rbenv versions | grep 2.2.2\"", "delta": "0:00:00.073502", "end": "2015-12-29 19:35:57.621104", "invocation": {"module_args": "$SHELL -lc \"rbenv versions | grep 2.2.2\"", "module_complex_args": {}, "module_name": "shell"}, "item": "deploy", "rc": 1, "start": "2015-12-29 19:35:57.547602", "stderr": "", "stdout": "", "stdout_lines": [], "warnings": []}, "deploy"], "rc": 2, "start": "2015-12-29 19:35:58.257234", "warnings": []}
stderr: ruby-build: definition not found: 2.2.2

The following versions contain `2.2.2' in the name:
  rbx-2.2.2

See all available versions with `rbenv install --list'.

If the version you need is missing, try upgrading ruby-build:

  cd /home/deploy/.rbenv/plugins/ruby-build && git pull
...ignoring

and

TASK: [zzet.rbenv | check if user ruby version is {{ rbenv.ruby_version }}] *** 

failed: [ansible] => (item=deploy) => {"changed": false, "cmd": "$SHELL -lc \"rbenv version | cut -d ' ' -f 1 | grep -Fx '2.2.2'\"", "delta": "0:00:00.055444", "end": "2015-12-29 19:35:59.077912", "item": "deploy", "rc": 1, "start": "2015-12-29 19:35:59.022468", "stdout_lines": [], "warnings": []}

Thanks for any help!

This happened to me because I was running with strategy: debug which stops at any exception. Note that the task itself expects this and includes irgnore_errors: yes. Run it once without debug and it should work thereafter (though I'm not sure if that's the best solution).

Edit: Another possibility is to set failed_when: false.
(Also, this is the first time that I found my own comment when I was trying to solve a problem. Thanks me-6-days-ago)

@zzet Is there a different way to implement the check without throwing errors? Having red output in ansible always captures my attention.
