Question

我正在尝试在Ubuntu 10.10上安装rails，但每次都找不到File：lib。 Ruby和Rubygems已正确安装。我已经看到这个问题发布在网络上，但没有解决方案适合我。我重新安装了rdoc，我仍然得到了相同的结果。

$ sudo gem install rails
...

我写了一篇detailed how-to guide on installing Ruby and Rails on Ubuntu 10.10来帮助你解决这个问题。

您应该避免使用Ruby的打包版本（即，避免使用来自apt-get install ruby的Ruby版本）。 Debian打包系统（Ubuntu使用）与Ruby期望的相冲突。

相反，您应该从源代码安装Ruby。

有一个名为RVM的好工具可以帮助你做到这一点。

# Install prerequisites
$ sudo apt-get install git curl wget

# Download and install RVM
$ bash < <( curl http://rvm.beginrescueend.com/releases/rvm-install-latest )

# Install RVM into your .bash_profile
$ cat >> ~/.bash_profile <<-PROFILE
> [[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm"
> PROFILE

# Load RVM into the current shell
$ rvm reload

# Install prerequisites
$ rvm notes
$ sudo apt-get install \
>   build-essential bison 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

# Install Ruby
$ rvm install ruby-1.9.2-p180 # latest version as of now
$ rvm use ruby-1.9.2-p180 --default

# Check it
$ ruby -v
$ which ruby
$ gem install rails
