Introduction
Are you encountering a frustrating “RuntimeError: Python 3.5 or later is required” error message when attempting to install libraries in your Python 3.4 environment? You’re not alone! In this blog post, we’ll dive into the causes of this issue and explore possible solutions to help you overcome it. So, let’s get started and resolve this obstacle that’s preventing you from utilizing those much-needed libraries!
Understanding the Error Message
When you run the pip install command to install a library, you may encounter the following error message:
code

raise RuntimeError("Python 3.5 or later is required")
RuntimeError: Python 3.5 or later is required
Causes of the Error
The “RuntimeError: Python 3.5 or later is required” error occurs because the library you are trying to install depends on a version of Python that is higher than the one you currently have (Python 3.4). Certain libraries and their dependencies may require features or improvements introduced in later versions of Python.
Solutions
- Upgrade Python to a Supported Version: One of the best solutions is to upgrade your Python installation to a supported version. Visit the Python website (https://www.python.org) or check out the list of currently supported Python versions at https://endoflife.date/python. Upgrading to a more recent version will provide access to a wider range of libraries and ensure compatibility with the latest advancements in the Python ecosystem.
- Virtual Environments: If upgrading Python is not feasible due to specific requirements or constraints, consider using virtual environments. Virtual environments allow you to create isolated Python environments with different versions and package configurations. By setting up a virtual environment with Python 3.5 or later, you can install the desired libraries without affecting your system-wide Python installation.
- Library Compatibility: In some cases, the library you are trying to install may have alternative versions or forks that are compatible with Python 3.4. Check the documentation or official website of the library for any available versions specifically designed for Python 3.4. Additionally, explore community forums and GitHub repositories for any workarounds or patches that address compatibility issues with older Python versions.
- Downgrade the Library: If no compatible version or workaround is available, you may consider downgrading the library itself. However, this approach should be approached with caution, as downgrading a library might result in the loss of new features, bug fixes, or security patches. Evaluate the consequences and risks before opting for this solution.
Conclusion
Encountering a “RuntimeError: Python 3.5 or later is required” error when attempting to install libraries in your Python 3.4 environment can be frustrating. However, by following the solutions mentioned above, you can overcome this obstacle and continue utilizing the power of various Python libraries. Remember to choose the most suitable solution based on your specific requirements and constraints.
We hope this article has provided you with valuable insights and actionable solutions to resolve the error. Don’t let compatibility issues hold you back from exploring the vast world of Python libraries!
