Spring will not start

I am receiving the following error when trying to start Spring (https://github.com/jonleighton/spring). I am running it in a Vagrant box with Ubuntu 12.04 LTS 12.04.

    vagrant@rails-starter-box:/vagrant/ticketee$ spring start

Solution

Because of Vagrant's read-only file system you need environment set the variable SPRING_TMP_PATH to somewhere outside of the /vagrant directory

run this at the command line

mkdir ~/spring_tmp; export SPRING_TMP_PATH=/home/vagrant/spring_tmp
spring start

then run

spring status

if spring is now running then add the following line to ~/.bashrc

export SPRING_TMP_PATH="/home/vagrant/spring_tmp" # Temp PATH for spring
