Question

我得到以下错误。

rails -v
/opt/ruby/lib/ruby/1.9.1/rubygems/dependency.rb:247:in `to_specs': Could not find      railties (>= 0) amongst [daemons-1.1.9, diff-lcs-1.1.3, expectations-2.0.0, faraday-0.8.9, faraday_middleware-0.8.8, ftpfxp-0.0.4, json-1.7.7, json-1.6.1, json-1.4.3, lumberg-1.1.1, metaclass-0.0.1, mime-types-1.24, mocha-0.12.7, multipart-post-1.2.0, mysql-2.8.1, rest-client-1.6.7, rspec-2.11.0, rspec-core-2.11.1, rspec-expectations-2.11.3, rspec-mocks-2.11.3, stomp-1.2.2, system_timer-1.2.4, systemu-1.2.0] (Gem::LoadError)
    from /opt/ruby/lib/ruby/1.9.1/rubygems/dependency.rb:256:in `to_spec'
    from /opt/ruby/lib/ruby/1.9.1/rubygems.rb:1231:in `gem'
    from /home/adsudxuy/ruby/gems/bin/rails:22:in `<main>'

我的Gemrc文件如下：

cat .gemrc
---
gem: --remote --gen-rdoc --run-tests
gemhome: /home/adsudxuy/ruby/gems
gempath: [/opt/ruby/lib/ruby/gems/1.9.1,
      /home/adsudxuy/ruby/gems]
rdoc: --inline-source --line-numbers

我的bash个人资料如下：＃开始＃.bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
    . ~/.bashrc
fi

# User specific environment and startup programs

#PATH=$PATH:$HOME/bin
PATH=$HOME/.gems/bin:$HOME/bin:$PATH

GEM_HOME=$HOME/.gems
GEM_PATH=$HOME/.gems:/usr/lib/ruby/gems/1.8

export PATH GEM_HOME GEM_PATH

#export PATH
#END

另外，供您参考，我的宝石环境如下：

gem env

Answer 1

尝试观察 railties gem的路径：

bundle show railties

如果失败，请尝试手动安装gem：

gem install railties

Answer 2

尝试安装通用ruby版本：

sudo apt-get install ruby-dev
