<h1 id="installing-ruby-with-rvm-on-alpine-linux">Installing Ruby with RVM on Alpine Linux</h1>
<p>2023-03-16</p>
<p>For some on-going projects I need to switch to different versions of <code>ruby</code>. Although there exist many step-by-step instructions on installing and configuring <code>rvm</code> for most Linux distros, there aren&#8217;t many focused on Alpine &#8220;daily drivers&#8221;.</p>
<p>So this post is more or less a helpful document for my future self. If it happens to help others then that&#8217;s an added bonus!</p>
<h2 id="simple-setup">Simple Setup</h2>
<p>Make sure you have the basic packages first:</p>
<pre><code>apk update
apk add curl gcc gnupg gpg dirmngr procps musl-dev linux-headers zlib zlib-dev openssl openssl-dev libssl1.1
</code></pre>
<p>Next download the latest <code>stable</code> version of <code>rvm</code> from Github, unpack it, place it in the proper user directory (~&#47;.rvm) and install any required libs:</p>
<pre><code>curl -sSL https:&#47;&#47;github.com&#47;rvm&#47;rvm&#47;tarball&#47;stable -o rvm-stable.tar.gz
echo &#39;export rvm_prefix="$HOME"&#39; &#62; ~&#47;.rvmrc
echo &#39;export rvm_path="$HOME&#47;.rvm"&#39; &#62;&#62; ~&#47;.rvmrc
mkdir rvm &#38;&#38; cd rvm
tar --strip-components=1 -xzf ..&#47;rvm-stable.tar.gz
.&#47;install --auto-dotfiles --autolibs=0
</code></pre>
<p>Now we can remove everything and properly link to <code>rvm</code>:</p>
<pre><code>cd ..&#47; &#38;&#38; rm -rf rvm-stable stable.tar.gz rvm
source ~&#47;.rvm&#47;scripts&#47;rvm
</code></pre>
<p>Now you can freely install any version of Ruby that you desire!</p>
<pre><code>rvm install ruby-X.X.X
</code></pre>
