<h2><a name="installing-leap_cli"></a>Installing leap_cli</h2>

<h3><a name="from-gem-for-a-single-user"></a>From gem, for a single user</h3>

<p>Install the latest:</p>

<pre><code>gem install --user-install leap_cli
</code></pre>

<p>Or install a particular version:</p>

<pre><code>gem install --version 1.8 --user-install leap_cli
</code></pre>

<p>Add the &ndash;user-install directory to your path:</p>

<pre><code>[ $(which ruby) ] &amp;&amp; PATH="$PATH:$(ruby -e 'puts Gem.user_dir')/bin"
</code></pre>

<h3><a name="from-gem-system-wide"></a>From gem, system wide</h3>

<p>Install the latest:</p>

<pre><code>sudo gem install leap_cli
</code></pre>

<p>Install a particular version:</p>

<pre><code>sudo gem install leap_cli --version 1.8
</code></pre>

<h3><a name="as-a-gem-built-from-source"></a>As a gem, built from source</h3>

<pre><code>sudo apt-get install ruby ruby-dev rake
git clone https://leap.se/git/leap_cli.git
cd leap_cli
git checkout develop
rake build
sudo rake install
</code></pre>

<h3><a name="the-develop-branch-from-source-for-a-single-user"></a>The “develop” branch from source, for a single user</h3>

<pre><code>sudo apt-get install ruby ruby-dev rake
git clone https://leap.se/git/leap_cli.git
cd leap_cli
git checkout develop
</code></pre>

<p>Then do one of the following to be able to run <code>leap</code> command:</p>

<pre><code>cd leap_cli
PATH=$PATH:`pwd`/bin
alias leap="`pwd`/bin/leap"
ln -s `pwd`/bin/leap ~/bin/leap
</code></pre>

<p>In practice, of course, you would put aliases or PATH modifications in a shell startup file.</p>

<p>You can also clone from <a href="https://github.com/leap/leap_cli">https://github.com/leap/leap_cli</a></p>

<h2><a name="running-different-leap_cli-versions"></a>Running different leap_cli versions</h2>

<h3><a name="if-installed-as-a-gem"></a>If installed as a gem</h3>

<p>With rubygems, you can always specify the gem version as the first argument to any executable installed by rubygems. For example:</p>

<pre><code>sudo gem install leap_cli --version 1.7.2
sudo gem install leap_cli --version 1.8
leap _1.7.2_ --version
=&gt; leap 1.7.2, ruby 2.1.2
leap _1.8_ --version
=&gt; leap 1.8, ruby 2.1.2
</code></pre>

<h3><a name="if-running-from-source"></a>If running from source</h3>

<p>Alternately, if you are running from source, you can alias different commands:</p>

<pre><code>git clone https://leap.se/git/leap_cli.git
cd leap_cli
git checkout develop
alias leap_develop="`pwd`/bin/leap`
</code></pre>
