ImportError: No module named dataflows

[kayakr]

Fresh install on macOS 10.13.6 High Sierra. I'm new to Python, following the tutorial at http://okfnlabs.org/blog/2018/08/29/data-factory-data-flows-introduction.html

09:08:25 jonathan:~/Documents/projects/datafactory (master) $ dataflows --help

Usage: dataflows [OPTIONS] COMMAND [ARGS]...

Options:
  --help  Show this message and exit.

Commands:
  init  Bootstrap a processing pipeline script.

09:08:29 jonathan:~/Documents/projects/datafactory (master) $ dataflows init https://rawgit.com/datahq/demo/_/first.csv

Writing processing code into first_csv.py
Running first_csv.py
Processing failed, here's the error:
python: VERSIONER_PYTHON_VERSION environment variable error (ignored)
Traceback (most recent call last):
  File "first_csv.py", line 1, in <module>
    from dataflows import Flow, load, dump_to_path, dump_to_zip, printer, add_metadata
ImportError: No module named dataflows

09:16:13 jonathan:~/Documents/CatalystIT/projects/datafactory (master) $ dataflows init

Hi There!
    DataFlows will now bootstrap a data processing flow based on your needs.

    Press any key to start...

[?] What is the source of your data?: File
 ❯ File
   Remote URL
   SQL Database
   Other

At first I thought maybe the rawgit.com URL is bad (it doesn't serve data now), but dataflows init https://raw.githubusercontent.com/datahq/demo/master/first.csv also generates the ImportError: No module named dataflows message.

This looks like a python installation issue - you have multiple versions of Python which are interfering with one another (the VERSIONER_PYTHON_VERSION environment variable error pretty much gives it away).

I found this SO question that might be relevant: https://stackoverflow.com/questions/15170871/python-path-error

For developing with Python on OSX, I very much recommend using pyenv - https://github.com/pyenv/pyenv. It allows you to use multiple versions of Python on your machine, without interfering in any way with the preinstalled/global versions.

@akariv Thanks for the response. I just reconstituted my homebrew python3 install and venv via https://www.digitalocean.com/community/tutorials/how-to-install-python-3-and-set-up-a-local-programming-environment-on-macos and the dataflows tutorial works ok.

BTW, the CSV URL still needs updating to https://raw.githubusercontent.com/datahq/demo/master/first.csv

Great, happy to hear! We'll update the URL in the demo - thank you for that.

@akariv is this updated yet?

[akariv]

Yes - the problem was just on the blog post.
