Setting .ruby-version in root directory doesn't work

[nagyt234]

I tried to set .ruby-version in root directory to set the default, but it does not work:

root@vmt3:~# rbenv version
system (set by /usr/local/rbenv/version) # BUT THERE IS NO SUCH FILE!!!

root@vmt3:~# cat /usr/local/rbenv/version
cat: /usr/local/rbenv/version: No such file or directory

root@vmt3:~# cat /.ruby-version 
1.9.3-p484

root@vmt3:~# rbenv versions
* system (set by /usr/local/rbenv/version)
  1.9.3-p484
  2.2.2

Rbenv is installed in /usr/local/rbenv/ from the git repository. Ruby 1.9.3-p484 and 2.2.2 are installed, no /usr/local/rbenv/version file exists.

Thanks for reporting. rbenv currently has a bug discovering the /.ruby-version file in the root directory. To set a global ruby version for the system, however, rbenv wants you to write to /usr/local/rbenv/version (even if it doesn't exist). So, instead of creating a /.ruby-version file in the root directory, which is not advisable since it requires root access to create and change, simply use the command:

rbenv global 1.9.3-p484

You should use rbenv global and rbenv local commands to get or set global/location versions of Ruby instead of writing to files manually.
