升级到Ruby2.0时出错

Question

基本上，当按照这些说明尝试安装Ruby2.0时：http://architects.dzone.com/articles/upgrading-ruby-20-mountain我遇到了困难。

具体在此步骤：“rvm install 2.0.0”

我收到以下错误：

Error running 'env LDFLAGS=-L/opt/sm/pkg/active/lib CFLAGS=-I/opt/sm/pkg/active/include CPATH=/opt/sm/pkg/active/include ./configure --prefix=/usr/local/rvm/rubies/ruby-2.0.0-p195 --with-opt-dir=/opt/sm/pkg/active --disable-install-doc --without-tcl --without-tk --enable-shared',
please read /usr/local/rvm/log/ruby-2.0.0-p195/1370731952_configure.log
There has been an error while running configure. Halting the installation.

按照命令提示符指令读取“/usr/local/rvm/log/ruby-2.0.0-p195/1370731952_configure.log”

configure.log文件：

See `config.log' for more details

请告知

好的，关键错误消息是configure: error: C compiler cannot create executables。您是否找到并查看config.log（与configure.log不同）？仔细检查您不仅安装了Xcode，还安装了command line tools。
