Problem installing ruby 1.9.2 using RVM

I get this error message when I rvm install 1.9.2

Error running 'make ', please read /Users/danielreardon/.rvm/log/ruby-1.9.2-p136/make.log There 开发者_开发百科has been an error while running make. Halting the installation.

I'm very very new to all this. Any suggestions?

Have you installed Apple's XCode development system? RVM requires that to install Ruby and many of the gems' native drivers. If not, download the latest version from Apple. Do NOT use the version on the Snow Leopard DVD because it's buggy.

Also, did you modify your ~/.bashrc or ~/.bash_profile file according to the "post install" section in RVM's installation page? SO many people forget that, but it's essential.

Also, before installing a Ruby via RVM, run rvm notes and make sure you've got all the prerequisites installed.
