Python 2.7环境下导入Tweepy 4.3.0库触发SyntaxError语法错误问题求助

Hey there, let's fix that syntax error you're running into with Tweepy!

Looking at your error traceback, the issue is clear: the line self, auth=None, *, cache=None, host='api.twitter.com', parser=None, uses keyword-only argument syntax (*), which is a feature introduced in Python 3.0. Python 2.7 doesn't recognize this syntax, hence the SyntaxError.

Why is this happening? Because the version of Tweepy you installed (4.3.0) dropped support for Python 2 entirely starting from version 4.0. Tweepy 4.x only works with Python 3.6 and above.

Two Solutions to Fix This #

Option 1: Downgrade Tweepy to a Python 2-compatible version #

The last Tweepy release that supports Python 2.7 is version 3.10.0. Uninstall your current version and install this older release:

pip uninstall tweepy -y
pip install tweepy==3.10.0

Once installed, your existing code should run without issues—Tweepy 3.10.0 doesn't use Python 3-exclusive syntax.

Option 2: Upgrade to Python 3 (Recommended Long-Term Fix) #

Python 2.7 reached end-of-life in 2020, meaning it no longer receives security updates or bug fixes. Upgrading to Python 3.6+ (e.g., 3.8, 3.10, or newer stable releases) is the better long-term solution.

After installing Python 3, reinstall Tweepy for Python 3:

pip3 install tweepy

Your existing code is already mostly Python 3-compatible (your print statements use function syntax, which works in both versions), so you can run it with python3 main.py once set up.

Verify Your Fix #

After making changes, confirm your Tweepy version to ensure it's correct:

# For Python 2
pip show tweepy

# For Python 3
pip3 show tweepy

Once the version matches your chosen solution, run your code again—it should successfully fetch your Twitter account details!
