Python version should be mentioned explicitly while spawning subprocess

[gshrikant]

Subprocess calls in guineapig.py (line 941, for example) invoke a Python child process using just python. This should probably be python2 or python3 explicitly depending on the version expected by the script. If a user has python aliased to python3 this would result in a confusing error message.

Same issue! So far, I can only soft-link my python to python2 again on my MacOS system.

Adding alias python='python2' to ~/.bash_profile does not resolve the problem.

I just pushed a fix to this, in 1.3.7 - you can now specify pythonCommand in --opts or use the env variable GP_PYTHON_COMMAND

10-605/gpigtut-1.3.7.tgz has a copy of the tutorial if you

It works now! Thank you.

It's compressed, you need to use -xvzf
