start failure

[e-letter]

Readers,

Discovered that unable to use python27, so used brightway2 with
python26 via activepython web site. Received command terminal error
starting the file 'bw2-web.py':

Can you post with a real name? This "e-letter" thing is getting flagged by my spam filter.

You will have to explain this a bit more. Python 2.7 was released in 2010, and it is certainly installable on almost every computer and CPU made today. Brightway2 is not compatible with 2.6 (it uses 2.7 features).

This says that the package `requests` wasn't installed. How did you install Brightway2? Requests should be a requirement for Brightway2, and should be installed automatically.

It caused many conflicts with existing packages (gedit, gnumeric,
file-roller, etc.) and therefore had to force a removal and revert to
python26

Used the instructions in the web site activepython, which showed a
version compatible with python26 ash installed 'requests'.
