Description

Ruby Version Manager (RVM)

RVM is a command-line tool which allows you to easily install, manage, and work with multiple ruby environments from interpreters to sets of gems.

:speech_balloon: copied from home page

Setup RVM on Ubuntu

  • Follow the instruction to setup RVM as suggested on the RVM Homepage

    • In addition the Rails developer need to be in the groups rvm and sudo to be able to install Ruby versions

  • Install the latest ruby version rvm install ruby-3.3.5

Integration with VSCode

  • Add the rvm group to the vscode user: sudo usermod -aG rvm vscode

  • Adjust the code-server to run with group rvm by modifying the configuration /usr/lib/systemd/system/[email protected]:

    sudo vi /usr/lib/systemd/system/[email protected]

===

[Unit]
Description=code-server
After=network.target

[Service]
Type=exec
ExecStart=/usr/bin/code-server
Restart=always
User=%i
Group=rvm

[Install]
WantedBy=default.target

===

sudo systemctl daemon-reload
sudo systemctl restart code-server@vscode

Set correct file permissions for the RVM directory

This is necessary because otherwise VSCode extensions, like Ruby LSP or RuboCop cannot be installed correctly

```Bash
# RVM installation directory
cd /usr/share

# Access for User and Group only
sudo chmod -R o-rwx rvm
# Ensure write and execution rights for the group
sudo chmod -R g+rwX rvm
# All files belong to the group rvm
sudo chgrp -R rvm rvm
# Newly created files and directory automatically belong to group rvm as well
sudo chmod -R g+s rvm
```

Setup RVM on FreeBSD

  • Follow the instruction to setup RVM:

    • Install GnuPG to verify the signed applications

      GnuPG is a complete and free replacement for PGP. Because it does not use the patented IDEA algorithm, it can be used without any restrictions. GnuPG is an RFC2440 (OpenPGP) compliant application.

      :speech_balloon: copied from package description

      sudo pkg install gnupg

    • Import GPG for RVM (see RVM security)

      \curl -sSL https://rvm.io/mpapis.asc | gpg --import -

> gpg: directory '/home/freebsd/.gnupg' created
> gpg: new configuration file '/home/freebsd/.gnupg/gpg.conf' created
> gpg: WARNING: options in '/home/freebsd/.gnupg/gpg.conf' are not yet active during this run
> gpg: keybox '/home/freebsd/.gnupg/pubring.kbx' created
> gpg: /home/freebsd/.gnupg/trustdb.gpg: trustdb created
> gpg: key D39DC0E3: public key "Michal Papis (RVM signing) <[email protected]>" imported
> gpg: Total number processed: 1
> gpg:               imported: 1

    • Install RVM installer (see RVM security)

      cd $HOME/bin
\curl -O https://raw.githubusercontent.com/rvm/rvm/master/binscripts/rvm-installer
chmod ug+x rvm-installer
\curl -O https://raw.githubusercontent.com/rvm/rvm/master/binscripts/rvm-installer.asc

gpg --verify rvm-installer.asc

> gpg: assuming signed data in 'rvm-installer'
> gpg: Signature made Tue Apr 14 02:05:41 2015 CEST using RSA key ID BF04FF17

    • Install RVM

      I change following options in contrast to the tutorial:

      1. use the rvm-installer script
      2. do not pollute my $HOME directory with unnecessary dot-files - see next step for $HOME/.profile enhancement
      3. because I currently do not understand the necessity of a rvm group, I do not pass the option --add-to-rvm-group to the installer script
      cd $HOME
rvm-installer --verify-downloads --ignore-dotfiles stable

# source necessary RVM scripts into current shell environment
source $HOME/.rvm/scripts/rvm

# test installation
type rvm | head -n 1

> rvm is a function

    • Enhance your $HOME/.profile to enable RVM automatically

      if [ `echo "$PATH" | grep -c "/usr/local/bin"` == 0 ] 
then
  export PATH="$PATH:/usr/local/bin" # Add standard commands to PATH
fi

if [ `echo "$PATH" | grep -c "/usr/local/share/bin"` == 0 ] 
then
  export PATH="$PATH:/usr/local/share/bin" # Add shared commands to PATH
fi

if [ `echo "$PATH" | grep -c "$HOME/.rvm/bin"` == 0 ] 
then
  export PATH="$PATH:$HOME/.rvm/bin" # Add RVM to PATH for scripting
fi

if [ -z $FIRST_RUN ]
then
  export PATH="$PATH:$HOME/.rvm/bin" # Add RVM to PATH for scripting

  [ -s "$HOME/.rvm/scripts/rvm" ](/HVboom/HowTo-DigitalOcean/wiki/--s-"$HOME/.rvm/scripts/rvm"-) && source "$HOME/.rvm/scripts/rvm" # Load RVM into a shell session *as a function*
  [ -r "$rvm_path/scripts/completion" ](/HVboom/HowTo-DigitalOcean/wiki/--r-"$rvm_path/scripts/completion"-) && source "$rvm_path/scripts/completion" # Enable completion of ram commands
fi
      • Tip: I created a template file in /usr/local/share/bash/.profile which is automatically copied, if such a file does not exists in the users home directory (see /usr/local/share/bash/profile)

  • Prepare RVM to use project specific configurations (see .rvmrc)

    # Install the requested Ruby version automatically
rvm_install_on_use_flag=1
# Fallback to the default ruby version
rvm_project_rvmrc_default=1
# Automatically use bundler, if a Gemfile is found
rvm_autoinstall_bundler_flag=1
    • Tip: I created a template file in /usr/local/share/bash/.rvmrc which is automatically copied, if such a file does not exists in the users home directory (see /usr/local/share/bash/profile)

  • Remove RVM warning, when using project specific Gemfiles rvm rvmrc warning ignore allGemfiles

Setup script to install RVM into a users home directory

  • Store the script in /usr/local/share/bin/setup_rvm

    #!/usr/bin/env bash

# Setup script for RVM (Ruby Version Manager) into a user home

## Get signed version

cd $HOME
# Import public key used to sign RVM
\curl -sSL https://rvm.io/mpapis.asc | gpg --import -

cd $HOME/bin
# Load the installer and the signature file
\curl -O https://raw.githubusercontent.com/rvm/rvm/master/binscripts/rvm-installer
chmod ug+x rvm-installer
\curl -O https://raw.githubusercontent.com/rvm/rvm/master/binscripts/rvm-installer.asc

# Verify the signature
gpg --verify rvm-installer.asc


## Install latest stable version of RVM

cd $HOME
$HOME/bin/rvm-installer --verify-downloads 0 --ignore-dotfiles stable

# source necessary RVM scripts into current shell environment
source $HOME/.rvm/scripts/rvm

# test installation
