Troubleshooting Pip Upgrade on CentOS 7: Solving the SyntaxError Issue

Is your attempt to upgrade pip on CentOS 7 resulting in repeated errors? You're not alone. Many users face similar issues, especially when working with older versions of Python and pip. In this guide, we’ll walk you through the problem and provide a step-by-step guide to resolve it effectively.

The Problem: Python 2.7.5 and Pip Errors

In the provided scenario, the user is operating on CentOS 7 with Python version 2.7.5. When they attempt to install a package using pip or upgrade pip, they encounter SyntaxError messages. Here’s a breakdown of the error:

When trying to install biopandas, a dependency on numpy fails because of a syntax error in the setup.py file.

Similarly, when attempting to upgrade pip, the same error arises, indicating that certain Python syntax being used is incompatible with Python 2.7.

This issue is primarily caused by using newer versions of packages that require Python 3.x features, which are not supported in Python 2.7.5.

Solution: Uninstalling and Reinstalling Setuptools

To address this issue, a two-step approach involving setuptools can be taken. Here’s how to do it step-by-step:

Step 1: Uninstall Setuptools

Upgrading will not only solve compatibility issues but also provide you with the benefits of the latest features and security improvements.
