How do I install libgit2 on Alipne linux

问题:

I am new to Docker and trying to use an Alpine docker image for my project. I am getting the following error when I am try to build the project.

gopkg.in/libgit2/git2go.v22
# pkg-config --cflags libgit2
pkg-config: exec: "pkg-config": executable file not found in $PATH

I think I need to install libgit2 but I am not able to:

bash-4.3# apk add libgit2
ERROR: unsatisfiable constraints:
  libgit2 (missing):
    required by: world[libgit2]

Thanks for any help.

libgit2 is not present in either of main or community repositories that come preconfigured in the standard Alpine image, so you'll have to add the testing repo first:

# echo http://dl-4.alpinelinux.org/alpine/edge/testing >> /etc/apk/repositories

Then update package caches:

# apk update

And finally install libgit2:

# apk add libgit2

As of the start 2017 libgit2 has been added to the main repository. You should be able to install now with the usual

apk update
apk add libgit2
