通过rbenv安装Ruby失败

Question

问题:我安装了ruby,但无法正确识别. 我正在关注部署到VPS:https://github.com/railscasts/335-deploying-to-a-vps

我在ubuntu 12.04 LTS上设置我的服务器来部署我的rails应用程序.我正在跟踪部署到VPS的railscast,并试图通过rbenv安装ruby.似乎一切都安装正确,但当我试图检查ruby版本时,它给了我错误.以下是我运行的命令.

'ruby' program can be found in the following packages:
 * ruby1.8

我该如何解决这个问题？

Answer 1

您不需要使用rbenv来安装特定版本的Ruby.而是使用ruby-build将1.9.3-p125安装到/usr/local:

ruby-build 1.9.3-p125 /usr/local/

或者,手动安装Ruby:

# Compile Ruby (instead of rbenv)
sudo apt-get -y install build-essential zlib1g-dev libssl-dev libreadline5-dev libyaml-dev
wget ftp://ftp.ruby-lang.org/pub/ruby/1.9/ruby-1.9.3-p125.tar.gz
tar -xvzf ruby-1.9.3-p125.tar.gz
cd ruby-1.9.3-p125/
./configure --prefix=/usr/local
make
sudo make install
sudo gem install bundler --no-ri --no-rdoc
