How to install executable gem?

[minhdanh]

I can install executable gem with this command after installing rvm successfully:

rvm rubygems current

But how to do this with rvm1-ansible?

[nickjj]

Did you do a system wide install? If so: /usr/local/rvm rubygems current

[minhdanh]

Hi, I didn't install it system wide. The error appears as I run this task:

- name: Install bundler
  sudo: yes
  sudo_user: webapp
  gem: name=bundler state=latest

It tells me that the executable gem is not found. So I guess I need to install gem first with this task:

- name: Install rubygems
  sudo: yes
  sudo_user: webapp
  shell: >
    executable=/bin/bash source ~/.rvm/scripts/rvm;rvm rubygems current
  environment:
    PATH: "{{ rvm_path }}:{{ ansible_env.PATH }}"

But this is not successful either. Yes, I'm not sure if that's the right way to call a command begin with rvm when I've already have the role rvm_io.rvm1-ruby. As I notice when rvm is being installed, it has a task called Install bundler if not installed. But the following task is also failed:

- name: Install gem dependencies
  sudo: yes
  sudo_user: webapp
  command: "bundle install --deployment --without=development,test chdir=/home/webapp/my-app" 

With the errors:

failed: [128.199.196.85] => {"cmd": "bundle install --deployment --without=development,test", "failed": true, "rc": 2}
msg: [Errno 2] No such file or directory
failed: [128.199.203.144] => {"cmd": "bundle install --deployment --without=development,test", "failed": true, "rc": 2}
msg: [Errno 2] No such file or directory

FATAL: all hosts have already failed -- aborting

Are you using version rvm1-ansible 1.3.6 or 1.3.7?

[minhdanh]

It's 1.3.7.

I faced a similar sympton described in https://github.com/rvm/rvm1-ansible/issues/46#issuecomment-99901857 (gem not found) For me the issue was gem (and other files) ended up in a different folder. In my case I had set up rvm1_install_path to /usr/local/rvm but rubies and gems had end up under /usr/local/lib/rvm. So I changed rvm1_install_path to the second path and things worked. It is as if when installing rvm all the paths ended up messed up.

Hi. I still have this problem and after hours of googling I still don't know how to solve this. in role main.yml

- name: Bundle project gems
  command: chdir="{{prj_path}}/web" bundle install --without development test

produces

..."bundle install" works from command line over ssh.

Can you help me please? Josef

[nickjj]

@Pepan Did you try the solution listed above?

[Pepan]

I found solution:

- name: Bundle project gems
  command: chdir="{{prj_path}}/web" bundle install --without development test
  environment:
    PATH: /usr/local/rvm/gems/ruby-2.2.3/bin:/usr/local/rvm/gems/ruby-2.2.3@global/bin:/usr/local/rvm/rubies/ruby-2.2.3/bin:/usr/lib64/qt-3.3/bin:/usr/local/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/usr/local/rvm/bin
    GEM_PATH: /usr/local/rvm/gems/ruby-2.2.3:/usr/local/rvm/gems/ruby-2.2.3@global

I confirm I had the same issue, and solved sort of the same way @Pepan did. Before the fix bundler gem was installed in default gemset - this is only available when you run "rvm use ruby-X.X.X" but we need it in any gemset: "rvm use ruby@gemset" and this is achieved by installing bundler gem in the "@global" gemset that is inherited by all the gemsets on given ruby. I realised this is a separate issue, so I opened a new one #72 I wonder if it's worth to merge this PR #71

[psk11]

I have installed ruby using rvm and I can install gems by doing ssh into the machine but its failing with ansible. Below is my playbook where I am trying to install rails 4.2.0

• name: Install Gem Rails command: "gem install rails -v 4.2.0"

And its giving error as - ERROR: While executing gem ... (Errno::EACCES)\n Permission denied - /var/lib/gems

[marekciupak]

I found solution:

- name: Bundle project gems
  command: chdir="{{prj_path}}/web" bundle install --without development test
  environment:
    PATH: /usr/local/rvm/gems/ruby-2.2.3/bin:/usr/local/rvm/gems/ruby-2.2.3@global/bin:/usr/local/rvm/rubies/ruby-2.2.3/bin:/usr/lib64/qt-3.3/bin:/usr/local/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/usr/local/rvm/bin
    GEM_PATH: /usr/local/rvm/gems/ruby-2.2.3:/usr/local/rvm/gems/ruby-2.2.3@global

Following version works for me for a single user instalation:

roles:
  - { name: rvm_io.ruby, rvm1_rubies: "['{{ ruby_version }}']" }
tasks:
  - name: Install gems
    bundler:
      state: present
      chdir: "{{ sample_app_path }}"
      executable: "{{ ansible_env.HOME }}/.rvm/gems/ruby-{{ ruby_version }}/bin/bundler"
      gem_path: "{{ ansible_env.HOME }}/.rvm/gems/ruby-{{ ruby_version }}"
    environment:
      PATH: "{{ ansible_env.HOME }}/.rvm/gems/ruby-{{ ruby_version }}/bin:\
             {{ ansible_env.HOME }}/.rvm/gems/ruby-{{ ruby_version }}@global/bin:\
             {{ ansible_env.HOME }}/.rvm/rubies/ruby-{{ ruby_version }}/bin:\
             {{ ansible_env.HOME }}/.rvm/bin:\
             {{ lookup('env', 'PATH') }}"
      GEM_PATH: "{{ ansible_env.HOME }}/.rvm/gems/ruby-{{ ruby_version }}:\
                 {{ ansible_env.HOME }}/.rvm/gems/ruby-{{ ruby_version }}@global"
