rbenv：在主目录外安装ruby

Question

I'm trying to install Ruby + Rails on Ubuntu 14.04. I need more than one user to have access to Ruby, so I installed rbenv with ruby-build in the /opt/.rbenv directory. Is that right?

If I try to install a version of Ruby using

rbenv install 2.1.3

it is installed in ~/username/.rbenv/versions , not in /opt/.rbenv/versions .

I don't want to give the second user access to the other user's home directory.

How can I install Ruby in /opt/.rbenv ? Or is there another solution?

Answer 1

You can use the RBENV_ROOT environment variable:

sudo RBENV_ROOT=/opt/.rbenv rbenv install 2.1.3

See documentation .
