HOWTO dev RVM
Follow these steps:
(Substitute DESIRED_RUBY_VERSION with the Ruby version you're willing to use; i.e.: 2.3.3, 2.5, 2.6.1, ...)
sudo apt-get install libgdbm-dev libncurses5-dev automake libtool bison libffi-dev
gpg --keyserver hkp://keys.gnupg.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3 7D2BAF1CF37B13E2069D6956105BD0E739499BDB
curl -sSL https://get.rvm.io | bash -s stable
source ~/.rvm/scripts/rvm
rvm install DESIRED_RUBY_VERSION
rvm use DESIRED_RUBY_VERSION --default
ruby -v-
Follow either the official installation steps to add the PGP key to the local list (on a fresh install) or install RVM with the commands above.
-
Make sure that RVM is loaded as a function in you current shell:
$> type rvm -- | head -n 1
rvm is a functionThe source command above reloads the shell configuration so that you can actually use the rvm function in your Bash console.
- Install the Ruby version required by most of the projects (in the example, "2.3.3") with:
$> rvm install 2.3.3
- Switch to the correct Ruby version with:
$> rvm use 2.3.3- Set which Ruby will be using when creating gemsets:
$> rvm use 2.3.3- Create a new, versioned gemset for a Project named "my_project", using the current Ruby version:
$> rvm gemset create my_project-1.00- List existing gemsets:
$> rvm list gemsets- Use a specific gemset:
$> rvm use 2.3.3@my_project-1.00(See Troubleshooting)
Since the gem capistrano-rvm uses rvm-check via SSH to check the RVM's installation and
expects RVM to be installed as a user (under a hidden .rvm/bin directory), use which rvm
to see where it is actually installed and make a symlink to the root's homedir,
if the expected path is missing:
$> which rvm
/usr/share/rvm/bin/rvm
$> cd /root
$> mkdir .rvm
$> cd .rvm
$> mkdir bin
$> cp -s /usr/share/rvm/bin/rvm /root/.rvm/bin/rvmThen, all Capistrano deploy commands should work as expected.
