El Capitan上的Homebrew-无法运行“ brew doctor”

Question

我正在尝试安装Ruby和Rails，但无法运行安装。 当我运行RVM时，我得到：

Error running 'requirements_osx_brew_libs_install autoconf automake libtool     pkg-config libyaml readline libksba openssl',
showing last 15 lines of /Users/Aman/.rvm/log/1448680507_ruby-2.2.1/package_install_autoconf_automake_libtool_pkg-config_libyaml_readline_libksba_openssl.log
++ case "$1" in
++ [[ -t 1 ]]
++ return 1
++ printf %b 'There were package installation errors, make sure to read the log.

Try `brew tap --repair` and make sure `brew doctor` looks reasonable.

Check Homebrew requirements https://github.com/Homebrew/homebrew/wiki/Installation\n'

++ case "$_system_version" in

Requirements installation failed with status: 1.

当我运行“ brew doctor”时，出现“错误：执行失败：/ usr / bin / otool -L / usr / bin / install_name_tool”
