If you’re encountering problems installing pywin32 on Heroku, chances are you’re not alone. This can be quite frustrating, especially if you’re working against a deadline. But don’t worry, there are a few things that you can do to resolve the issue.

First and foremost, make sure that you have all the necessary dependencies installed. Pywin32 is known to have complex dependencies that can sometimes cause problems. So, check that you have everything installed both locally and on your Heroku instance. You should also consider using a virtual environment for your installation to keep everything clean and neat.

If that still doesn’t resolve the issue, you may need to update your version of Python or Windows. Some features of pywin32 are only available with certain versions of Python, so ensure that you’re using the right one. Similarly, some versions of Windows don’t support pywin32, so you may need to upgrade your operating system.

Finally, if all else fails, don’t hesitate to seek help. You can consult the Pywin32 documentation or ask the community for guidance on how to best resolve installation issues. And once you get it working, you’ll reap the benefits of pywin32’s powerful features and functionalities.

So, next time you run into trouble installing pywin32 on Heroku, keep these tips in mind and stay proactive. With a little effort and perseverance, you’ll soon be up and running in no time.

Trouble Installing Pywin32 on Heroku?

A Common Problem for Windows Users

If you’re a Windows user trying to deploy your Python app on Heroku, you might run into trouble when installing Pywin32. This is a common issue because Pywin32 requires a compatible version of Microsoft Visual C++ installed on your system, which Heroku does not have by default. In this article, we’ll discuss this problem and provide some solutions to help you get past this roadblock.

What is Pywin32?

A Windows-Specific Module for Python

Pywin32 is a Python module that provides access to many of the features of the Win32 API, a set of functions used by Windows operating systems. It allows Python scripts to interact with Windows components such as the registry, file system, and clipboard. Pywin32 is particularly useful for developers who write Windows-specific applications in Python.

The Heroku Environment

A Linux-Based System

One challenge in using Pywin32 on Heroku is that Heroku runs on a Linux-based system, whereas Pywin32 is designed for Windows. This can cause compatibility issues because Pywin32 relies on specific Windows operating system features that are not available on Linux. As a result, Pywin32 must be installed differently on Heroku than it would be on a Windows machine.

Options for Dealing with the Compatibility Problem

Choose the Right Version of Pywin32

The first option for dealing with the compatibility problem is to choose the correct version of Pywin32 that is compatible with the version of Python you are using. Make sure to check the compatibility matrix on the Pywin32 project page and select the appropriate version of Pywin32 for your specific configuration. This will help ensure that Pywin32 functions properly on Heroku.

Building Pywin32 from Source

Create a Custom Build of Pywin32

If you cannot find a compatible pre-built version of Pywin32, you can try building it from source code. This requires compiling the code yourself and creating a custom build of Pywin32 that is specific to your system configuration. This method can be time-consuming and complicated, but it may be necessary if you need to use Pywin32 with a Python version that is not officially supported.

Using a Windows Environment

Run Heroku Locally on Your Windows Machine

If all else fails, you can try running Heroku locally on your Windows machine instead of deploying the app to Heroku directly. By running the application locally, you can take advantage of the compatibility features of a native Windows environment and have access to Pywin32 as normal. Once everything is working correctly on your local machine, you can then deploy the app to Heroku. This option may not be feasible for all developers, but it is a useful workaround for those who are struggling with compatibility issues.

Comparison Chart

Option Pros Cons
Choose the Right Version of Pywin32 Easy to do, no compilation required. May not work with certain Python versions, no customization options available.
Build Pywin32 from Source Allows for customization and compatibility with unsupported Python versions. Can be time-consuming and complicated, requires compiling code.
Use a Windows Environment Allows for full access to Pywin32 as intended, no compatibility issues. Not practical for all developers, not guaranteed to solve all issues.


Installing Pywin32 on Heroku can be a difficult and frustrating process, but there are several options available to overcome compatibility issues. Choosing the correct version of Pywin32, building from source, or running Heroku locally are all viable alternatives depending on your specific needs. By understanding the problem and exploring possible solutions, you can ensure that your Python application will function as intended, regardless of the operating system environment.

Are you experiencing trouble installing Pywin32 on Heroku? You’re not alone. Here are some common questions people also ask and solutions to help you resolve the issue:

  1. Why won’t Pywin32 install on Heroku?
  2. Pywin32 is designed for Windows machines, so it may not be compatible with Heroku’s Linux-based system. You may need to use an alternative library or find a workaround.

  3. Can I install Pywin32 on Heroku using pip?
  4. It is possible, but it may require some additional steps such as installing MinGW, which provides a Windows-like environment on Linux. However, this approach is not recommended as it can lead to compatibility issues.

  5. What is the best alternative to Pywin32 on Heroku?
  6. If you need to work with Windows-specific features, you can try using the Python for .NET library instead of Pywin32. For other tasks, there are many other libraries available that are compatible with Heroku, such as NumPy, Pandas, and Flask.

  7. How can I ensure my Python code runs smoothly on Heroku?
  8. Before deploying your code to Heroku, be sure to test it locally on a Linux-based machine to ensure compatibility. Also, make sure to specify all necessary dependencies in your requirements.txt file.

  9. Is there any support available for Pywin32 installation issues on Heroku?
  10. Heroku provides extensive documentation and community support through their forums and GitHub repository. You can also contact their support team for further assistance.
