I am trying to install git-annex using homebrew. After installing brew, when i typed
brew install git-annex in the commandline, it showed "git-annex: no bottle available!". I also want to download datalad, after following the steps on datalad handbook, it appeared the same problem as installing git-annex brew install datalad "Error: datalad: no bottle available!"
git-annex and datalad don't have bottles for M1 Macs right now. The following pages will say "Apple Silicon Big Sur" under the section "Bottle (binary package) installation support" when the bottles are added, but at the time of writing, they only have bottles for Intel Big Sur.
Maybe try running brew install --build-from-source git-annex and see if it installs successfully on your machine.
