Ubuntu RVM Rails bash command not found

Question

I just installed ubuntu, and after that I wanted to install RVM with rubies and rails 3.1.

The installs went fine, but when I want to create a rails application, it cannot find the rails command.

I know I can create an alias, but when rvm changes its gemset, will the alias path be wrong right?

This is my .bashrc file (/home/user/.bashrc):

# ~/.bashrc: executed by bash(1) for non-login shells. # see /usr/share/doc/bash/examples/startup-files (in the package bash-doc) # for examples # If not running interactively, don't do anything [ -z "$PS1" ] && return # don't put duplicate lines in the history. See bash(1) for more options # ... or force ignoredups and ignorespace HISTCONTROL=ignoredups:ignorespace # append to the history file, don't overwrite it shopt -s histappend # for setting history length see HISTSIZE and HISTFILESIZE in bash(1) HISTSIZE=1000 HISTFILESIZE=2000 # check the window size after each command and, if necessary, # update the values of LINES and COLUMNS. shopt -s checkwinsize # make less more friendly for non-text input files, see lesspipe(1) [ -x /usr/bin/lesspipe ] && eval "$(SHELL=/bin/sh lesspipe)" # set variable identifying the chroot you work in (used in the prompt below) if [ -z "$debian_chroot" ] && [ -r /etc/debian_chroot ]; then debian_chroot=$(cat /etc/debian_chroot) fi # set a fancy prompt (non-color, unless we know we "want" color) case "$TERM" in xterm-color) color_prompt=yes;; esac [[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # uncomment for a colored prompt, if the terminal has the capability; turned # off by default to not distract the user: the focus in a terminal window # should be on the output of commands, not on the prompt #force_color_prompt=yes if [ -n "$force_color_prompt" ]; then if [ -x /usr/bin/tput ] && tput setaf 1 >&/dev/null; then # We have color support; assume it compliant with Ecma-48 # (ISO/IEC-6429).

So, I really don't know how to make this work ...

Help is appreciated!

thanks

You need

Add rvm to your .bashrc by adding a line like

 [[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # Load RVM into a shell session *as a function* 

This will allow you to load rvm when starting a new bash session

create a new gemset when you want new rails.

Workflow should work as follows

 $ mkdir new_rails_app $ cd new_rails_app $ vim .rvmrc # edit the .rvmrc to use the correct Gemset Something like rvm use ruby-1.9.2-p180@new _rails_app --create #save and exit vim $ rvm rvmrc load # you should see a prompt that your Gemset was loaded $ gem install rails $ rails new . 

You now have a working rails directory for the new application using rvm. There are other small tricks, such as automatically loading your rvmrc, but I left it just for the “easiest” route.

I meet the problem "command not found: rails " too, but I use oh-my-zsh for the command line and I fix the problem copy the line

 PATH=$PATH:$HOME/.rvm/bin # Add RVM to PATH for scripting [[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm" # This loads RVM into a shell session. 

from the ~ / .bashrc file to ~ / .zshrc and it works well. Hope he can help you.
