If only your user (let's call it user1) needs docker-sync, then I suggest you to install the gem for user user1 by running (as user1, not root) :

gem install --user-install docker-sync

Then, add docker-sync binary location (probably ~/.gem/ruby/<ruby_version>/bin) to your PATH :

export PATH=$PATH:~/.gem/ruby/<ruby_version>/bin
user_78040580

another version of this can be

gem install docker-sync --user-install -n /usr/local/bin

you will not have to export the path if you install this way
