I just upgraded my Mac to Mac OS X v10.7 (Lion), and now Git is gone:
$ git
-bash: git: command not found
How can I get Git back?
You have to find where the Git executable is and then add the folder to the PATH environment variable in file .bash_profile.
Using terminal:
Search for Git:
sudo find / -name git
Edit the .bash_profile file. Add:
PATH="<Directory of Git>:$PATH"
Git is back :-)
Anyway, I suggest you to install Git using MacPorts. In this way you can easily upgrade your Git instance to the newest release.
There are a couple of points to this answer.
Firstly, you don't need to install Xcode. The Git installer works perfectly well. However, if you want to use Git from within Xcode - it expects to find an installation under /usr/local/bin. If you have your own Git installed elsewhere - I've got a script that fixes this.
Second is to do with the path. My Git path used to be kept under /etc/paths.d/
However, a Mac OS X v10.7 (Lion) install overwrites the contents of this folder and the /etc/paths
file as well. That's what happened to me and I got the same error. Recreating the path file fixed the problem.
It's part of Xcode. You'll need to reinstall the developer tools.
If you do not want to install Xcode and/or MacPorts/Fink/Homebrew, you could always use the standalone installer: https://sourceforge.net/projects/git-osx-installer/
You can always use MacPorts...
