问题
I have a script that runs perfectly from command line:
/home/anaconda2/bin/python /project_folder/script.py
I added some details below:
$ echo $PYTHONPATH
:/project_folder/
$ which python
/home/anaconda2/bin/python
Which runs the script perfectly, flawlessly.
Then from within crontab (which has been successful for another script that didn't have local import issues) I can't get the script to run.
Crontab of code that doesn't work:
PYTHONPATH=/project_folder
* * * * * /home/anaconda2/bin/python /project_folder/script.py
Nothing happens. It's killing me and much of my time trying to figure this one out - any help much appreciated.

I resolved it via creating a wrapper shell script. Ugly in that i'm exporting the python path each time, but it works.
#!/bin/bash
export PYTHONPATH="${PYTHONPATH}:/project_folder"
source ~/.bash_profile
cd /project_folder && /my/anaconda/location/bin/python /project_folder/cript.py
