我第一次尝试在Mac上安装Ruby on rails。
我在终端窗口上运行了以下命令 -
rvm install 2.0.0
但我一直收到这个错误。
Error running './configure --prefix=/Users/tusharmathur/.rvm/rubies/ruby-2.0.0-p0 --with-opt-dir=/usr/local/opt/libyaml:/usr/local/opt/readline:/usr/local/opt/libxml2:/usr/local/opt/libxslt:/usr/local/opt/libksba:/usr/local/opt/openssl:/usr/local/opt/sqlite --disable-install-doc --without-tcl --without-tk --enable-shared',
please read /Users/tusharmathur/.rvm/log/ruby-2.0.0-p0/configure.log
There has been an error while running configure. Halting the installation.
我也看到了configure.log，这里是信息 -

以下是一些如何为XCode安装命令行工具的截图（您可以从Mac AppStore安装XCode）：
安装命令行工具后，您的计算机上将有一个C / C ++编译器。
