为什么在安装Ruby 1.9.3时会出现配置错误？

有人知道这个错误意味着什么吗？我正在尝试安装Ruby 1.9.3

Error running ' ./configure --prefix=/Users/coreycallahan/.rvm/rubies/ruby-1.9.3-p125 --enable-shared --disable-install-doc --with-libyaml --with-opt-dir=/Users/coreycallahan/.rvm/usr ', please read /Users/coreycallahan/.rvm/log/ruby-1.9.3-p125/configure.log
There has been an error while running configure. Halting the installation.

你有权限在你编译的目录中写入吗？

你使用的是什么操作系统？Mac OS X Lion 10.7.3（11D50d）你可能应该执行

cat/Users/coreycalahan/.rvm/log/ruby-1.9.3-p125/configure.log

并将输出打印到问题中。或者，

cat/Users/coreycalahan/.rvm/log/ruby-1.9.3-p125/configure.log | pbcopy

，这样您就不必复制它了。尝试查看尝试查看：尝试将文件复制到您知道有写入权限的目录中。

configure: error: C compiler cannot create executables
