XyPriss CLI — Installation Guide #

This document provides step-by-step instructions for installing the XyPriss CLI (xyp, also known as xfpm) on all supported operating systems.

Requirements #

Before installing, ensure the following prerequisites are met:

  • Node.js: Version 18 or later is required.
  • Internet connection: Needed to download the optimized Rust engine during installation.

Installation (Unified Installer) #

XyPriss is distributed through a unified installer that automatically detects your operating system and CPU architecture, then installs the appropriate binary and configures your PATH.

Linux & macOS #

Open a terminal and run:

curl -sL https://xypriss.nehonix.com/install.js | node

Windows (PowerShell) #

Run the following command in PowerShell:

Invoke-WebRequest -Uri https://xypriss.nehonix.com/install.js -OutFile install.js; node install.js; Remove-Item install.js

The installer will download the engine, configure aliases, and make the CLI globally accessible.

Updating XyPriss #

To update to the latest version, simply re-run the installation command for your platform.

If an existing installation is detected, the installer will prompt you before overwriting it with the newest version.

Uninstallation #

To completely remove XyPriss and all related aliases:

Linux / macOS #

curl -sL https://xypriss.nehonix.com/install.js | node - uninstall

Windows (PowerShell) #

Invoke-WebRequest -Uri https://xypriss.nehonix.com/install.js -OutFile install.js; node install.js uninstall; Remove-Item install.js

This removes the engine binaries and PATH mappings created by the installer.

Verification #

After installation, verify that XyPriss is available by running:

xyp

or

xfpm

You should see the current XFPM version along with architecture information.

Troubleshooting #

Permission denied (Linux/macOS) #

If you encounter an EACCES error, the installer may require elevated privileges to create symlinks in /usr/local/bin. You will be prompted for your password if necessary.

PowerShell execution policy (Windows) #

If PowerShell blocks the script, enable local script execution with:

Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser

Then re-run the installer.

Command not found after installation #

If xyp or xfpm is not recognized:

  1. Restart your terminal to refresh environment variables.
  2. On Linux/macOS, ensure /usr/local/bin is included in your $PATH.
  3. On Windows, verify that $HOME\.xypriss\bin exists in your User PATH (added automatically by the installer).
