I upgraded xcode from 7.3.1 to 8.1 and also I update homebrew using [brew update]. after that I could use [brew upgrade]. It shown the following warning message
Warning: You are using a pre-release version of Xcode. You may encounter build failures or other breakages. Please create pull-requests instead of filing issues.
I used [brew config] and it shown the following info
HOMEBREW_VERSION: 1.0.8-54-g8019afb ORIGIN: https://github.com/Homebrew/brew.git HEAD: 8019afb60ad321b0f14f60b00c23d7fb098d35c2 Last commit: 6 days ago Core tap ORIGIN: https://github.com/Homebrew/homebrew-core Core tap HEAD: 83f73d73fac8229ac523bf839b8a5913de05bf08 Core tap last commit: 3 hours ago HOMEBREW_PREFIX: /usr/local HOMEBREW_REPOSITORY: /usr/local/Homebrew HOMEBREW_CELLAR: /usr/local/Cellar HOMEBREW_BOTTLE_DOMAIN: https://homebrew.bintray.com CPU: quad-core 64-bit haswell Homebrew Ruby: 2.0.0-p648 Clang: 8.0 build 800 Git: 2.9.3 => /Applications/Xcode.app/Contents/Developer/usr/bin/git Perl: /usr/bin/perl Python: /usr/bin/python Ruby: /usr/local/bin/ruby => /usr/local/Cellar/ruby/2.3.1_2/bin/ruby Java: 1.8.0_25 macOS: 10.11.6-x86_64 Xcode: 8.1 CLT: 22.214.171.124.1.1461711523
I think the last line of above info [CLT] means command line tools and its version is 7.3.1..., I think it should be 8.1 because Xcode is 8.1. How can I upgrade CLT from 7.3.1 to 8.1?
