基本上，当尝试按照以下说明安装 Ruby2.0 时：http://architects.dzone.com/articles/upgrading-ruby-20-mountain我碰壁了。

具体到这一步：“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”时

配置日志文件：

好吧，关键的错误信息是configure: error: C compiler cannot create executables. 您是否找到并查看config.log（不同于configure.log）？仔细检查您是否不仅安装了Xcode ，还安装了命令行工具。
