I have Homebrew installed, I'm trying to install RVM with:

rvm install 1.9.3-head

and I get this error:

Installing required packages:gcc46
Error running 'requirements_osx_brew_libs_install gcc46',
please read /Users/mike/.rvm/log/1384918134_ruby-1.9.3-head/package_install_gcc46.log
Requirements installation failed with status: 1

brew doctor says I'm ready to brew.

In the log I see:

Error: Download failed: ftp://gcc.gnu.org/pub/gcc/infrastructure/gmp-4.3.2.tar.bz2

  • Why are you installing 1.9.3-head? That’s a pre-release version of an older version… If you’re starting out go with the latest release: 2.0.0-p247. – Andrew Marshall Nov 20 '13 at 04:03
  • Thanks Andrew I'll go with 2.0.0-p247, I read some post warning against the bundled OSX Ruby so 1.9.3 was purely to see how rvm is used. – MikeW Nov 20 '13 at 04:46

Ruby 1.9.3+ supports compiling with Clang (which you do have) instead of GCC, so make RVM compile with Clang instead:

rvm install 1.9.3 --with-gcc=clang

When I upgraded to mavericks from mountain lion it somehow started ignoring my dev-tools (like gcc, etc.) try

xcode-select --install

When upgraded to OSX 10.12 and installing ruby 2.3.1 these steps fixed the issue. 

 brew install homebrew/versions/gcc46

if there are any linking issues related to any lib please follow the instructions for example 

brew link --overwrite libtool
brew link --overwrite libgpg-error

Once the installation of gcc46 is successful you could 

rvm install 2.3.1
