macos - Unable to run git on Mac OS Big Sur

Question

Unable to run git on new MacBook running Big Sur

When I try to run git, I receive the following error: xcrun: error: unable to load libxcrun (dlopen(/Library/Developer/CommandLineTools/usr/lib/libxcrun.dylib, 0x0005): could not use '/Library/Developer/CommandLineTools/usr/lib/libxcrun.dylib' because it is not a compatible arch).

I followed the method of forcing which architecture loads, suggested here, but still, I’m experiencing the error

Now, after running that suggestion I am seeing the following error: ‘manpath: error: unable to load libxcrun (dlopen(/Library/Developer/CommandLineTools/usr/lib/libxcrun.dylib, 5): no suitable image found. Did find: /Library/Developer/CommandLineTools/usr/lib/libxcrun.dylib: mach-o, but wrong architecture /Library/Developer/CommandLineTools/usr/lib/libxcrun.dylib: mach-o, but wrong architecture).’

I also installed home-brew prior to that error message, although I don’t see how that would be related.

I really lack experience interacting with Xcode. I feel like on my previous Mac I was just able to get up and running, without any of this hassle, but it’s been awhile so perhaps I'm forgetting.

How can I identify if Xcode and Command Line Tools are properly installed? If they are not, what is the recommended way to add them?

Edit: I tried installing homebrew to see if I could use it as a work-around, and tried using it to install git, but received the following error:

'brew install git Updating Homebrew... Error: Cannot install in Homebrew on ARM processor in Intel default prefix (/usr/local)! Please create a new installation in /opt/homebrew using one of the "Alternative Installs" from: https://docs.brew.sh/Installation'

I am on a Macbookpro with the new M1 chip- could that be related?

Answer 1

You can also get git from https://brew.sh/, which I believe is fairly common!

With the edit, I don't have an Apple Silicon chip to test with, but the brew docs say it should be installed to /opt/homebrew (literally untar in that path)

If this is a fresh install and not upgrading an existing one, however, you may not be able to get away from having Xcode as you'll almost-certainly require some compiler or component for a few packages. Existing installs should move the path or delete and rebuild (collect all your top-level packages with brew leaves && brew list -1 --cask)

brew install git

You may also need/want to provide a resolution for this warning if it appears

hint: Pulling without specifying how to reconcile divergent branches is
hint: discouraged. You can squelch this message by running one of the following
hint: commands sometime before your next pull:
hint:
hint:   git config pull.rebase false  # merge (the default strategy)
hint:   git config pull.rebase true   # rebase
hint:   git config pull.ff only>    # fast-forward only
hint:
hint: You can replace "git config" with "git config --global" to set a default
hint: preference for all repositories. You can also pass --rebase, --no-rebase,
hint: or --ff-only on the command line to override the configured default per
hint: invocation.

pull.ff only is a reasonable choice, as it'll it will only do a fast-forward if you have a local conflict when attempting to pull (modified local and remote)

git config --global pull.ff only
