Ghostscript Installation

Windows

1. Download Ghostscript:

   • Visit the Ghostscript download page.
   • Download the appropriate installer for Windows (64-bit or 32-bit).

2. Install Ghostscript:

   • Run the downloaded installer and follow the installation instructions.

3. Add Ghostscript to the System PATH:

   • Open the Start Menu, search for "Environment Variables", and select "Edit the system environment variables".
   • In the System Properties window, click the "Environment Variables..." button.
   • In the Environment Variables window, find the "Path" variable in the "System variables" section and select it, then click "Edit...".
   • Click "New" and add the path to the Ghostscript bin directory (e.g., C:\Program Files\gs\gs10.03.0\bin).
   • Click "OK" to close all dialog boxes.

4. Verify the Installation:

   • Open a Command Prompt and type gswin64c -v (or gswin32c -v for the 32-bit version).
   • You should see output displaying the Ghostscript version.

5. Create an Alias in PowerShell:

   • Open a Command Prompt and type gswin64c -v (or gswin32c -v for the 32-bit version).
   • You should see output displaying the Ghostscript version.

Based on the output you provided, it seems that the Ghostscript path (C:\Program Files\gs\gs10.03.0\bin) is included in your PowerShell PATH. However, the gs command is still not recognized. Here are a few more steps to resolve this issue:

Create an Alias in PowerShell

1. Navigate to the Ghostscript bin directory:

   cd "C:\Program Files\gs\gs10.03.0\bin"

2. List the files to confirm the executable name:

   Get-ChildItem

1. Create an Alias in PowerShell. If the executable is not gs.exe, create an alias for convenience.

2. If the executable is gswin64c.exe, create an alias in PowerShell:

Set-Alias -Name gs -Value "C:\Program Files\gs\gs10.03.0\bin\gswin64c.exe"

3. Test the alias:

gs -v

4. Add the Alias to Profile for Persistence: To make the alias persistent across PowerShell sessions, add it to your PowerShell profile.

1. Open the PowerShell profile script:

   if (!(Test-Path -Path $PROFILE)) {
       New-Item -ItemType File -Path $PROFILE -Force
   }
   notepad $PROFILE

2. Add the alias command to the profile:

   Set-Alias -Name gs -Value "C:\Program Files\gs\gs10.03.0\bin\gswin64c.exe"

3. Save and close the file.

4. Restart PowerShell and test the gs command:

   gs -v

** 5. Verify Execution Policy** Ensure the execution policy allows for the script in the profile to run:

1. Check the current execution policy:

   Get-ExecutionPolicy

2. Set the execution policy to RemoteSigned if necessary:

   Set-ExecutionPolicy RemoteSigned -Scope CurrentUser

macOS

1. Install Homebrew (if not already installed):

   /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

2. Update Homebrew:

   brew update

3. Install Ghostscript:

   brew install ghostscript

4. Verify the Installation:

   gs --version
