RVM: Ruby Version Manager - 'rvm pkg install readline'

Quick fix

Remove all the manually installed packages:

$ rm -rf $rvm_path/usr

Find the requirements (follow the instructions):

$ rvm requirements

Reinstall ruby:

$ rvm reinstall 1.9.3

Readline

If you have an error when compiling pertaining to readline, you may need to attempt installing with the procedure defined below.

$ rvm pkg install readline
$ rvm reinstall 1.9.2 --with-readline-dir=$rvm_path/usr

Note that this error occurs most often when having a MacPorts, Fink, or Homebrew installed readline on your system. The next most often is when the readline development headers are not available at all. The above commands solve this by having RVM compile a local version inside ~/.rvm/usr and then telling the ruby install to use it. If you have readline already installed using one of the above-mentioned package managers, you can use that readline by exchanging the location such as the following:

$ rvm reinstall 1.9.2 --with-readline-dir=/usr/local/Cellar/readline/x.x.x

Note: In the above case, we are compiling using the Homebrew readline installation. In the example, as well, you would need to replace 'x.x.x' with the correct version string.

If you have already installed your Ruby then you can manually recompile readline as follows. Be sure to first install the readline development headers and/or package as above. For example with 1.9.2-p0 and system readline development headers installed do the following.

$ cd $HOME/.rvm/src/ruby-1.9.2-p0/ext/readline
$ ruby extconf.rb
$ make install

If you used 'rvm pkg install readline' then alter the above to:

$ cd $HOME/.rvm/src/ruby-1.9.2-p0/ext/readline
$ ruby extconf.rb -- --with-readline-dir="$HOME/.rvm/usr"
$ make install

If you would like to automatically use the RVM default you can override config/db ruby configure setting in user/db like this:

# ~/.rvm/user/db or /usr/local/rvm/user/db
ruby_configure_flags=--enable-shared --disable-install-doc --with-readline-dir=/Users/wayneeseguin/.rvm/usr

In case of compilation problems try:

$ rvm --skip-autoreconf pkg install readline
