No module named 'gphoto2' #141

Open FizzyMUC opened 5 years ago

FizzyMUC commented 5 years ago

Dear all,

I recently installed the photobooth, following the installation guideline provided here. However I'm experiencing an issue when starting the box via "python -m photobooth" out of the virtual environment. The application itself loads up, but when I hit start the spinning wheel just stays there forever. The terminal shows (besides some other lines) the following issue:

File "/home/pi/photobooth/photobooth/camera/CameraGphoto2.py", line 25, in import gphoto2 as gp ImportError: No module named 'gphoto2'

I tried installing it again, however the system then shows that I already have the latest version installed.

What am I missing here? :)

I should add: It works when I select gphoto-commandline! But then I don't see the GUI with the image. Can anyone help?

I should mention that I'm running on Raspbian Stretch Desktop, together with a Canon 6D.

Hi @FizzyMUC , First you need to activate your virtual environment. source .venv/bin/activate Afterwards you need to install the gphoto library via pip install. sudo apt install gphoto2 libgphoto2-dev # to use gphoto2

Hope this solves your issue!

FizzyMUC commented 5 years ago

Thanks, will try later! Then I suggest to update the manual, because there is not written to install the library within the virtual environment if I'm not mistaken.

oelegeirnaert commented 5 years ago

If you install it globally it should work as well... But I guess you didn't installed it at all.

FizzyMUC commented 5 years ago

Yes I did. In this case (I had gphoto2 already installed) it mentioned that one additional file will be downloaded and installed only (the libgphoto2-dev) and I remember wondering if the -dev was another package. So it IS installed, and also I assume globally. But let me check when I get home tonight...

FizzyMUC commented 5 years ago

Just checked... "libgphoto2-dev is already the latest version (2.5.12-1)"

Strange...

apt always installs things globally - it is the package manager for the OS. However, PIP is a package manager for python and inside a virtual environment it installs packages locally.

I thing @oelegeirnaert was already on the right track but posted the wrong command to install the PIP package. In fact, gphoto must be installed correctly as the command line module works.

@FizzyMUC did you run pip install -e . after activating the virtual environment? See also https://github.com/reuterbal/photobooth/blob/master/INSTALL.md#install-photobooth-with-dependencies for the relevant step.

FizzyMUC commented 5 years ago

Hi @reuterbal. I did run it but honestly nothing happened. After a couple minutes I killed the process. When I add the invidual package behind pip install -e . there is an error message...

reuterbal commented 5 years ago

That very much sounds like there is something broken with your Python setup, virtual environment, etc. Please provide the output of the following commands after activating your virtual environment: python --version pip freeze

There is indeed gphoto2 missing, which should have been installed when you run pip install -e .. You can try to install it manually using pip install gphoto2.
