今天爱分享给大家带来Error: homebrew-core is a shallow clone.【解决方法】，希望能够帮助到大家。
cd /usr/local/Homebrew/Library/Taps/homebrew rm -rf homebrew-core brew upgrade
Error: homebrew-core is a shallow clone. To `brew update`, first run: git -C /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core fetch --unshallow This restriction has been made on GitHub's request because updating shallow clones is an extremely expensive operation due to the tree layout and traffic of Homebrew/homebrew-core and Homebrew/homebrew-cask. We don't do this for you automatically to avoid repeatedly performing an expensive unshallow operation in CI systems (which should instead be fixed to not use shallow clones). Sorry for the inconvenience!
