On my Debian server I have a user called "deployer" that does not have sudo access, and has RVM installed.
When installing Ruby using "deployer", like 1.9.3, it triggers a task to install dependencies
"Installing requirements for debian, might require sudo password."
which fails and stops installation because "deployer" can not sudo.
I don't want to add "deployer" into the sudoers list, and don't want to install RVM for some other user just for a one-time use for installing dependencies.
What is the correct way to install that dependencies? Or how do I list them to install manually?
This is indeed a new feature of RVM called autolibs, which automatically installs dependencies.
If you have already installed RVM, and it is asking you for your sudo password, you can disable autolibs:
$ rvm autolibs disable
$ rvm requirements # manually install these
$ rvm install ruby
Otherwise, you can install RVM without autolibs with this command:
$ \curl -L https://get.rvm.io | bash -s -- --autolibs=read-fail
I understand the motivation, but find it rather annoying. I do not want to put my sudo password into RVM, nor for that matter Bundle! Please community, stop doing this.
