$ brew info readline readline: stable 8.0.0 (bottled) [keg-only] Library for command-line editing https://tiswww.case.edu/php/chet/readline/rltop.html /usr/local/Cellar/readline/7.0.3_1 (46 files, 1.5MB) Poured from bottle on 2018-06-26 at 09:48:16 /usr/local/Cellar/readline/7.0.5 (46 files, 1.5MB) Poured from bottle on 2018-07-30 at 18:56:16 /usr/local/Cellar/readline/8.0.0 (48 files, 1.5MB) Poured from bottle on 2019-02-01 at 11:40:21 From: https://github.com/Homebrew/homebrew-core/blob/master/Formula/readline.rb ==> Caveats readline is keg-only, which means it was not symlinked into /usr/local, because macOS provides the BSD libedit library, which shadows libreadline. In order to prevent conflicts when programs look for libreadline we are defaulting this GNU Readline installation to keg-only. For compilers to find readline you may need to set: export LDFLAGS="-L/usr/local/opt/readline/lib" export CPPFLAGS="-I/usr/local/opt/readline/include" For pkg-config to find readline you may need to set: export PKG_CONFIG_PATH="/usr/local/opt/readline/lib/pkgconfig" ==> Analytics install: 493,453 (30 days), 992,713 (90 days), 3,374,936 (365 days) install_on_request: 57,851 (30 days), 99,242 (90 days), 316,807 (365 days) build_error: 0 (30 days)
使いたいバージョンに切り替える。
brew switch readline 7.0.5
なぜ
気軽に brew install hoge
した結果、readlineがUpdateされて、Tigが使えなくなったので、readlineのバージョンを切り替えたかった。
$ tig dyld: Library not loaded: /usr/local/opt/readline/lib/libreadline.7.dylib Referenced from: /usr/local/bin/tig Reason: image not found zsh: abort tig
他に影響がないかはそのとき考える…。
