Question

这似乎与发布的其他一些问题相似，但实际上是一个不同的问题，并且有不同的（较新的）版本（因此，新问题）。

在Ubuntu 10.10 Maverik的适度全新安装上，我尝试使用RVM安装Rails，就像我之前在其他发行版上所做的那样。

以下是我采取的大致步骤：

已安装的RVM：bash < <(curl -s https://rvm.beginrescueend.com/install/rvm)
使用apt-get安装了一堆依赖项（curl，zlib-dev，g ++，openssl，apache2-dev，libsqlite3-dev，libreadline5-dev）
已安装的Ruby：rvm install 1.9.2; rvm use 1.9.2 --default
已安装的乘客（与Apache一起使用）：rvm gem install passenger
构建Apache Passenger mod：passenger-install-apache2-module

请注意，我实际上在这里遇到了一个不相关的问题：它无法对openssl进行依赖性检查。我发现仅执行ruby -e 'require "openssl"'会导致错误。因此，按照我在http://www.ruby-forum.com/topic/90083#175543找到的说明解决了src/ruby-1.9.2-p290/ext/openssl/中的问题，然后乘客模块安装成功。
决定为rails3创建一个gemset，因为我打算稍后测试3.1：rvm use --create 1.9.2@rails3
已安装的导轨：rvm gem install rails

所有这些似乎都没有任何障碍（除了来自ri和RDoc一代的几个警告）。但是，现在如果我输入rails（在新的shell登录后），我只会得到：

The program 'rails' is currently not installed.  You can install it by typing:
apt-get install rails

但是，我的路径是：

/usr/local/rvm/gems/ruby-1.9.2-p290@rails3/bin:/usr/local/rvm/gems/ruby-1.9.2-p290@global/bin:/usr/local/rvm/rubies/ruby-1.9.2-p290/bin:/usr/local/bin:/usr/local/sbin:/usr/sbin:/usr/bin:/sbin:/bin

和rvm info说：

ruby-1.9.2-p290@rails3:

    RUBYOPT:      ""

所以，我对一些Rails / Ruby / Ubuntu专家的问题是：这里发生了什么？如果我只需要在PATH中添加一些内容以允许bash找到rails，我就无法弄清楚是什么。执行find / usr / local / rvm -name rails的结果是：

/usr/local/rvm/src/rvm/scripts/extras/rails
/usr/local/rvm/scripts/extras/rails
/usr/local/rvm/gems/ruby-1.9.2-p290/gems/passenger-3.0.7/test/ruby/shared/rails
/usr/local/rvm/gems/ruby-1.9.2-p290/gems/passenger-3.0.7/test/stub/rails_apps/3.0/empty/script/rails

/usr/local/rvm/gems/ruby-1.9.2-p290/doc/actionmailer-3.0.9/rdoc/lib/rails

但是尝试直接执行/usr/local/rvm/gems/ruby-1.9.2-p290/bin/rails只会给出：

/usr/local/rvm/rubies/ruby-1.9.2-p290/lib/ruby/site_ruby/1.9.1/rubygems/dependency.rb:247:in `to_specs': Could not find rails (>= 0) amongst [rake-0.8.7] (Gem::LoadError)

    from /usr/local/rvm/gems/ruby-1.9.2-p290/bin/rails:18:in `<main>'

（我不知道这是否是一个合理的尝试）

以防万一我没有提供足够的信息:) - rvm gem list给出：

任何帮助或指示非常感谢。与此同时，我将继续为此烦恼。

Answer 1

使用gem install rails代替rvm gem install rails

使用RVM在Ubuntu 10.10上安装Rails 3.0.9 - 路径中没有rails命令
