Issues with Python picamera

[bludelft]

I've installed and tested my picamera. I'm able to take a picture with the command line. However, when I try to use python, I get an error.

I installed with:

Code: Select all

 sudo apt-get install python-picamera

When I try to use python, I get:

Code: Select all

I'm seeing the same issue. Any luck with this?

[jigar234]

Figured it out.

run:
sudo apt-get update && sudo apt-get upgrade

I have the exact same problem but the solution listed didnt work for me. It took a very long time and then reset itself and then repeated the error message upon my retrying the run the python program.

also note, im crazy new at this but do have other programming knowledge(ish)

[Eze323]

should anyone else end up with this issue it seems i fixed it,

ran:

sudo apt-get install python-picamera python3-picamera python-rpi.gpio

it said I had to run:

sudo dpkg --configure -a

so I did and then ran the code listed in the post above:

sudo apt-get update && sudo apt-get upgrade

and then happiness returned...
