While installing Ruby 2.1.3 on Yosemite, a permission denied error happens near the end of installation:

mkdir: /etc/openssl: Permission denied

While running rvm install with sudo might fix this error, when the command is not run with sudo, it should still work (e.g. by asking current user's password).

we have code to do the sudo here https://github.com/wayneeseguin/rvm/blob/06e93b166ff9593be632b59dd2ba0e4f70e901e9/scripts/functions/osx-ssl-certs#L10:

requirements_osx_update_openssl_cert_create_dir()
{
  [[ -d "$ssl_dir" ]] || mkdir -p "$ssl_dir" || __rvm_try_sudo mkdir -p "$ssl_dir" ||
  {
    typeset __ret=$?
    rvm_error "Can not create directory '$ssl_dir' for certificates."
    return ${__ret}
  }
}

what version of RVM is this?

[behrangsa]

It is version 1.25.34.

the above commit should clarify it (run rvm get head), but as the directory already exist you could not reproduce it without removing it first
