Ubuntu下使用RVM 安装Rails

使用Ubuntu版本：11.04
1.安装RVM
bash < <(curl -s https://raw.github.com/wayneeseguin/rvm/master/binscripts/rvm-installer)
2.安装Ruby
RVM安装完成后可以使用rvm requirements命令查看安装可选项。
执行rvm install 1.9.2

设置1.9.2 作为默认的Ruby版本
rvm use 1.9.2 --default
报错提示
RVM is not a function, selecting rubies with 'rvm use ...' will not work.
解决方法
执行echo '[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm" # Load RVM function' >> ~/.bash_profile然后重启Terminer再执行source .bash_profile这里还可以直接把这段命令写进/etc/profile
ubuntu:~$ rvm use 1.9.2 --defaultUsing /home/wenpeng/.rvm/gems/ruby-1.9.2-p290

安装rails 需要的lib

sudo apt-get install build-essential openssl libreadline6 libreadline6-dev curl git-core zlib1g zlib1g-dev libssl-dev libyaml-dev libsqlite3-0 libsqlite3-dev sqlite3 libxml2-dev libxslt-dev autoconf libc6-dev ncurses-dev automake libtool bison subversionsudo apt-get install build-essential libssl-dev libreadline5 libreadline5-dev zlib1g zlib1g-dev

gem install rails
如果出现问题的话需要remove掉ruby然后重新安装
rvm remove rubyrvm install 1.9.2rvm use 1.9.3 --defaultgem install rails

如果在启动rails server的过程中提示No JavaScripts Run time 有两个解决方法
解决方法1：

Adding the following gems to my Gemfile solved the issue:

gem 'execjs'
gem 'therubyracer'

Then of course:

这里需要先bundle install therubyracer
然后bundle install



解决方法2：

安装nodejs

lijg@lijg-desktop:~/workruby/helloapp$ sudo apt-cache search nodejs
password for lijg:
coffeescript - interpreter and compiler for the CoffeeScript language
nodejs - Node.js event-based server-side javascript engine
nodejs-dbg - Node.js event-based server-side javascript engine (debug)

nodejs-dev - Development files for Node.js
