brew如何安装指定版本软件

查看brew安装版本信息

Chaim:python Chaim$ brew info qt5 qt: stable 5.10.1 (bottled), HEAD [keg-only] Cross-platform application and UI framework https://www.qt.io/ /usr/local/Cellar/qt/5.10.1 (9,375 files, 295.1MB) Poured from bottle on 2018-02-28 at 16:45:54 From: https://github.com/Homebrew/homebrew-core/blob/master/Formula/qt.rb ==> Dependencies Build: pkg-config 鉁� Optional: mysql 鉁�, postgresql 鉁� ==> Requirements Build: xcode 鉁� Required: macOS >= 10.8 鉁� ==> Options --with-docs Build documentation --with-examples Build examples --with-mysql Build with mysql support --with-postgresql Build with postgresql support --without-proprietary-codecs Don't build with proprietary codecs (e.g. mp3) --HEAD Install HEAD version ==> Caveats We agreed to the Qt opensource license for you. If this is unacceptable you should uninstall. This formula is keg-only, which means it was not symlinked into /usr/local, because Qt 5 has CMake issues when linked. If you need to have this software first in your PATH run: echo 'export PATH="/usr/local/opt/qt/bin:$PATH"' >> ~/.bash_profile For compilers to find this software you may need to set: LDFLAGS: -L/usr/local/opt/qt/lib CPPFLAGS: -I/usr/local/opt/qt/include For pkg-config to find this software you may need to set: PKG_CONFIG_PATH: /usr/local/opt/qt/lib/pkgconfig
