I've run across that before with other setups and it has nothing to do with radiant. So good news it's not a radiant problem, bad news is that doesn't solve your problem.
As for RVM I strongly suggest using it on a development machine.. The last time I set it up I took some notes on the process. I've pasted them below. rvm requires curl so lets install it, and ruby/rails requires a bunch of stuff so lets make sure it's all installed sudo apt-get -y curl install build-essential sqlite3 libsqlite3-dev imagemagick libmagick9-dev git-core mysql-server mysql-admin libmysqlclient-dev zlib-bin libssl-dev libncurses5-dev libreadline5 and now install rvm bash < < (curl -s https://rvm.beginrescueend.com/install/rvm) edit .bash.rc and change at top #[ -z "$PS1" ] && return if [[ -n "$PS1" ]] ; then at bottom add if [ -f ~/.rvmprompt ]; then . ~/.rvmprompt fi fi [[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # Load RVM into a shell session *as a function* Save the following between the === as ~/.rvmprompt Note this part isn't necissary it just changes your command prompt to show what ruby and gemset you are at. === ##.rvmprompt function __git_dirty { git diff --quiet HEAD &>/dev/null [ $? == 1 ] && echo "!" } function __git_branch { __git_ps1 " %s" } function __my_rvm_ruby_version { local gemset=$(echo $GEM_HOME | awk -F'@' '{print $2}') [ "$gemset" != "" ] && gemset="@$gemset" local version=$(echo $MY_RUBY_HOME | awk -F'-' '{print $2}') # [ "$version" == "1.8.7" ] && version="" local full="$version$gemset" [ "$full" != "" ] && echo "$full " } bash_prompt() { local NONE="\[\033[0m\]" # unsets color to term's fg color # regular colors local K="\[\033[0;30m\]" # black local R="\[\033[0;31m\]" # red local G="\[\033[0;32m\]" # green local Y="\[\033[0;33m\]" # yellow local B="\[\033[0;34m\]" # blue local M="\[\033[0;35m\]" # magenta local C="\[\033[0;36m\]" # cyan local W="\[\033[0;37m\]" # white # emphasized (bolded) colors local EMK="\[\033[1;30m\]" local EMR="\[\033[1;31m\]" local EMG="\[\033[1;32m\]" local EMY="\[\033[1;33m\]" local EMB="\[\033[1;34m\]" local EMM="\[\033[1;35m\]" local EMC="\[\033[1;36m\]" local EMW="\[\033[1;37m\]" # background colors local BGK="\[\033[40m\]" local BGR="\[\033[41m\]" local BGG="\[\033[42m\]" local BGY="\[\033[43m\]" local BGB="\[\033[44m\]" local BGM="\[\033[45m\]" local BGC="\[\033[46m\]" local BGW="\[\033[47m\]" local UC=$W # user's color [ $UID -eq "0" ] && UC=$R # root's color PS1="$B\$(__my_rvm_ruby_version)$Y\h$W:$EMY\w$EMW\$(__git_branch)$EMY\$(__git_dirty)${NONE} $ " } bash_prompt unset bash_prompt === chmod +x .rvmprompt rvm install 1.8.7 You also might need to do a gem update --system Now to install radiant. rvm use 1.8.7 rvm gemset create radiant rvm use @radiant gem install radiant --pre now to activate the radiant gemset when ever you need to just do a rvm use 1.8.7@radiant Bob
