About

renv will help setup the appropriate system environment variables so that RubyGems will be installed under the current directory in a .gem directory for the currently used version of Ruby. The gem directory's bin/ directory is also added to $PATH. This is a reasonably simple way to help users install their RubyGems locally and per-project or in a common directory for easier cleanup later.

Installation

renv is designed to be sourced when a new shell is loaded via /etc/profile.d which will work for all users, system-wide. On most systems, this should work (run as a root user or each command via sudo):

mkdir -p /etc/profile.d
curl -sSfL \
  https://raw.githubusercontent.com/fnichol/renv/master/renv.sh \
  -o /etc/profile.d/renv.sh
chmod 0644 /etc/profile.d/renv.sh

Alternatively, you can simply source a downloaded copy of renv.sh whenever you need it, for example:

source ~/.renv.sh

Usage

Activating renv in a project directory

The default subcommand will set the appropriate system environment variables so that gems will be installed to and read from under ./.gem by default.

$ renv

Resetting the environment

To unset appropriate system environment variables and return to the state before renv was run, use:

$ renv reset

Checking the status of the environment

To check the status of the appropriate system environment variables:

$ renv status
