Arvados CLI tools are written in Ruby and Python.  To use the @arv@ command, you can either install the @arvados-cli@ gem via RubyGems or build and install the package from source.  The @arv@ command also relies on other Arvados tools.  To get those, install the @arvados-python-client@ and @arvados-cwl-runner@ packages, either from PyPI or source.

h2. Prerequisites

# "Install Ruby":../../install/ruby.html
# "Install the Python SDK":../python/sdk-python.html

The SDK uses @curl@ which depends on the @libcurl@ C library.  To build the module you may have to install additional packages.  On Debian 10 this is:

<pre>
$ apt-get install build-essential libcurl4-openssl-dev
</pre>

h2. Install from RubyGems

<notextile>
<pre>
# <code class="userinput">gem install arvados-cli</code>
</pre>
