How to fix? ImportError: pycurl: libcurl link-time version is older than compile-time version

Question

I have this error when I run tests on a conda environment which I built from specs in environment.yml

File "utils.py", line 5, in <module>
    import pycurl
ImportError: pycurl: libcurl link-time version (7.29.0) is older than compile-time version (7.55.1)

The environment.yml file used to build the conda env:

name: indices_python
channels:
- defaults
- conda-forge
dependencies:
- coverage 
- coveralls
- nco
- netcdf4
- nose
- numba
- numpy
- pandas
- pycurl
- pynco
- python=3
- scipy

The command I'm running (on Linux):

$ python -W ignore -m unittest tests/test_*.py

How can I fix this and/or how to prevent this from happening in the future?

pip install --upgrade --force-reinstall --no-cache-dir --ignore-installed pycurl==7.43.0.2

it'd be nice it this answer had information on getting the latest version number of pycurl. I have the exact same error as the OP, but for the version numbers. – JayRugMan Jul 12 '23 at 14:28
Add this: https://pypi.org/project/pycurl/#history – JayRugMan Jul 12 '23 at 15:01
