Can't install pygit2 in Raspberry Pi 3

[mariocosme]

Hi! I'm trying to install bazarr on my rpi3 which is already running sonarr. All other depencies are installed with success except for this pygit2.

Already tried to install it differently but it didn't work as well.

Here is the log:

As you can see, I'm using python version 2.7.9. Any ideas?

Hi Mario,

First, thank you to give a try to bazarr!

pygit2 is failing to install because you don't have libgit2 install on osmc. You probably gonna need to build it from source.

Be advise that you are using the version 0.26.x of pygit2 witch is good. You need the same version of libgit2 so it could work fine.

https://libgit2.github.com/docs/guides/build-and-link/

If you take a look at dockerfile, you going to see witch package need to be installer:
apt-get install -y build-essential python-dev python-pip python-setuptools libjpeg-dev zlib1g-dev git libgit2-dev libffi-dev
Be aware that the libgit2 package is only available on Debian since version 10 Buster. Like I said, building from source is probably what you're gonna have to do.

Try this and come back to give me some feeback!

[mariocosme]

Thanks for the quick reply. I installed all those packages (including libgit2-dev) without any issues. When I now run the pip install -r requirements.txt is does exit with a different error but it is still unable to install pygit2 successfully.

Here is the trace log (too big for the ssh terminal so I just paste the end):

[morpheus65535]

You’ve installed an incompatible version of libgit2. It’s too old.

You need to build it from source, as mentionned before.

You absolutely need the 0.26.x version of libgit2.

[mariocosme]

Okay. Built and installed libgit2 from source as build instructions

Still getting an error when installing bazarr dependencies:

It’s more a pygit2 vs libgit2 problem. I think you’re going to need some help from the developers of those software. :-/
