NOTE: This applies to both open source and commercial editions of Chocolatey.

1. Ensure you are set for organizational deployment

Please see the organizational deployment guide

  • Open Source or Commercial:
    • Proxy Repository - Create a proxy nuget repository on Nexus, Artifactory Pro, or a proxy Chocolatey repository on ProGet. Point your upstream to Packages cache on first access automatically. Make sure your choco clients are using your proxy repository as a source and NOT the default community repository. See source command for more information.
    • You can also just download the package and push it to a repository Download

3. Enter your internal repository url

(this should look similar to

4. Choose your deployment method:

choco upgrade ironpython -y --source="'STEP 3 URL'" [other options]

See options you can pass to upgrade.

See best practices for scripting.

Add this to a PowerShell script or use a Batch script with tools and in places where you are calling directly to Chocolatey. If you are integrating, keep in mind enhanced exit codes.

If you do use a PowerShell script, use the following to ensure bad exit codes are shown as failures:

choco upgrade ironpython -y --source="'STEP 3 URL'" 

Write-Verbose "Exit code was $exitCode"
$validExitCodes = @(0, 1605, 1614, 1641, 3010)
if ($validExitCodes -contains $exitCode) {
  Exit 0

Exit $exitCode

Comparison of IronPython vs. C# for 'Hello World'


using System;
class Hello
    static void Main() 
        Console.WriteLine("Hello World");

print "Hello World"
IronPython is a Dynamic Language that runs on the .NET DLR ([Dynamic Language Runtime]( in contrast with VB.NET and C# which are [static languages](

IronPython can also import DLL files compiled in other languages and use functions defined therein. For example:

import clr
from System.Windows.Forms import *

VERIFICATION Verification is intended to assist the Chocolatey moderators and community in verifying that this package's contents are trustworthy.

This package is published by the IronPython Project itself. The binaries are identical to other package types published by the project, in particular the IronPython nuget package.

In cases where actual malware is found, the packages are subject to removal. Software sometimes has false positives. Moderators do not necessarily validate the safety of the underlying software, only that a package retrieves software from the official distribution point and/or validate embedded software against official distribution point (where distribution rights allow redistribution).

Chocolatey Pro provides runtime protection from possible malware.
