在Mac OS X Lion上安装Ruby 1.9.3时出错
我正在尝试在MAC OS X Lion上安装Ruby 1.9.3和Rails。 （我的Xcode是4.3版）（我已经安装了Rails 3.2.2）
无论我使用：
rvm install 1.9.3 --with-gcc=clang 要么：
rvm install 1.9.3
我的终端显示：
Error running 'make ', please read /Users/AlexHo/.rvm/log/ruby-1.9.3-p125/make.log There has been an error while running make. Halting the installation.
有谁遇到过同样的情况？

我自己遇到了这个问题，经过大量的努力和搜索（没有一个网站有完整的解决方案），这就是我最终提出的：
curl -O ftp://ftp.gnu.org/gnu/readline/readline-6.2.tar.gz tar xzvf readline-6.2.tar.gz cd readline-6.2 ./configure --prefix=/usr/local cd shlib sed -e 's/-dynamic/-dynamiclib/' Makefile > Makefile.good mv Makefile.good Makefile cd .. make sudo make install cd .. rvm install 1.9.3 -C --with-readline-dir=/usr/local/
试着看一下，似乎你的问题是readline，而rvm有一个关于使用readline错误的整个部分。
