# Xygeni CLI Prerequisites

## Prerequisites <a href="#prerequisites" id="prerequisites"></a>

The following software is required for the Xygeni scanner to work properly

{% tabs %}
{% tab title="Mac/Linux" %}

* `Java 17 or higher`
* `unzip` and `curl` (only for CLI installation)
* Most scanner commands need `git`. Version 2.32 or higher is recommended.
  {% endtab %}

{% tab title="Windows" %}

* `Java 17 or higher`
* `PowerShell` (only for CLI installation)
* Most scanner commands need `git`. Version 2.32 or higher is recommended.
  {% endtab %}
  {% endtabs %}

{% hint style="warning" %}
It’s important to ensure that the **JAVA\_HOME** environment variable points to the directory where Java is installed, which may or may not be done automatically depending on your platform. Additionally, you need to make sure that the $JAVA\_HOME/bin directory is included in your system’s PATH so that you can access the Java executable from anywhere on your system.
{% endhint %}

Some commands may need additional tools. As dependencies are resolved using the build and package manager tools, the `deps` and `suspectdeps` commands require the following tools for the associated ecosystem:

* JavaScript / Node: `npm`, `yarn` and `bower`.
* Python: `pip` and `pipdeptree`.
* Java: Apache Maven (`mvn`).
* Ruby: Ruby Gems (`bundle`)
* Golang: `go` toolchain.
* PHP: `composer`.
* .Net: `dotnet`.

See [Opens Source Scan](/xygeni-products/open-source-security-oss/dependency-scanner.md) for full details on the tools required for analyzing the dependencies for each ecosystem.

{% hint style="info" %}
As Xygeni scans are typically run in CI/CD pipelines, the commands needed are usually the ones used at build time, so normally it is not necessary to install any extra tool in the CI/CD runner. In any case, the [Xygeni Scanner Docker image](/xygeni-scanner-cli/xygeni-cli-overview/xygeni-cli-docker-image.md) may be used when necessary.
{% endhint %}

{% hint style="info" %}
Xygeni Scanner needs **connectivity** to Xygeni servers.

Please be sure that access is enabled to xygeni.io (<https://api.xygeni.io> and <https://get.xygeni.io>).
{% endhint %}
