how do I make a python program run from a bash shell?
Posted on 2014-11-22
on a raspberry pi I have a python script which runs without error from within Idle3 (sudo /usr/bin/idle3) When I try to run it from a shell script it fails with the error message "ImportError: No module named pytz". It has no problem finding the other modules (picamera, time, and datetime) I installed the pytz package using apt-get.
My searches have yielded suggestions relating to PATH, python installation etc. I cannot find documentation that has helped.

Are you running it as
python script.py
or
python3 script.py
(in case pytz is only installed in Python3)
python script.py
or
python3 script.py
(in case pytz is only installed in Python3)
Im guessing you are using the wrong shebang.
type
e.g. the command yields /path/to/python3
and use its output as the shebang for the script and try again.
1st linx of the script should look like
then you should be able tu run it with ./scriptname.py
type
which python3
e.g. the command yields /path/to/python3
and use its output as the shebang for the script and try again.
1st linx of the script should look like
#!/path/to/python3
then you should be able tu run it with ./scriptname.py

Doug, I think you may have selected the wrong answer. Whether or not you give any points to me, you should at least give some to Andreas!
simon,
thanks for pointing that out. I did make a mistake in accepting my own comment as the answer. I have accepted Andreas's answer.
This is the first time I've posted a question so I was unfamiliar with the process.
