Using a fresh instance of Alpine:

  • install all required packages
  • clone the redash repo and checkout v7.0.0
  • create a fresh virtualenv
  • run -
    source venv/bin/activate && pip install -r requirements.txt -r requirements_dev.txt -r requirements_all_ds.txt

It errors out on pymapd==0.7.1 with the message of:
RuntimeError: Python version >= 3.5 required.

So I create a python3 virtual env and run the pip install again
This time it fails on:
MySQL-python==1.2.5 with this error: ModuleNotFoundError: No module named 'ConfigParser'
This is an error associated with running that pkg in python3.

There is currently no support for python3 for the MySQL-python pkg.
To get pymapd to work with python2 the version needs to be <0.8

How are people getting around this issue

Interesting. It looks like that MySQL-python version (~2014) is coming from here:

Wonder if we need to use a different MySQL connector? The GitHub repo for that one looks unmaintained.

Redash does not support Python 3 yet. If pymapd==0.7.1 requires Python 3 now it’s a recent change, as it wasn’t the case in the past. If you don’t need MapD support, just remove it from requirements_all_ds.txt and move on with Python 2 setup.

It’s strange though – our CI builds the Docker image regularly with Python 2 and we didn’t have any issues with our current dependencies. Are you sure the problem was with pymapd? Can you add a log?

Thanks.
