使用Python3.5搭配GeoAlchemy2遇“No Module Named Utils”错误求简易解法

Hey there! That error pops up because newer versions of GeoAlchemy2 dropped support for Python 3.5, and the internal utils module references changed in those updates. Here are two straightforward fixes:

1. Install a Python 3.5-compatible version of GeoAlchemy2 #

You'll need an older release of GeoAlchemy2 that still supports Python 3.5. The last major version range compatible with 3.5 is 0.9.x and below. Run this command in your terminal:

pip install "geoalchemy2<1.0"

This tells pip to grab the latest available GeoAlchemy2 version older than 1.0, which plays nicely with Python 3.5.

2. Ensure your SQLAlchemy version is also compatible #

GeoAlchemy2 depends on SQLAlchemy, and newer SQLAlchemy versions (1.4+) also dropped Python 3.5 support. If you already have a newer SQLAlchemy installed, downgrade it with:

pip install "sqlalchemy<1.4"

This makes sure all dependencies work together without conflicts.

Quick verification #

To confirm everything is set up right, run a simple import test in your Python shell:

from geoalchemy2 import Geometry

If this doesn't throw an error, you're ready to use GeoAlchemy2 with your Python 3.5 environment.
