使用RVM在Ubuntu 10.10上安裝Rails 3.0.9 - 在路徑中沒有rails命令

這似乎與其他一些發佈的問題類似，但實際上是一個不同的問題，並且與不同的（更新的）版本（因此，新問題）。使用RVM在Ubuntu 10.10上安裝Rails 3.0.9 - 在路徑中沒有rails命令

對於Ubuntu 10.10 Maverik的全新安裝，我嘗試使用RVM安裝Rails，就像我之前在其他發行版上所做的一樣。

這裏大致我採取的步驟：

安裝RVM：bash < <(curl -s https://rvm.beginrescueend.com/install/rvm)
安裝了一堆使用依賴apt-get的（捲曲，zlib的-dev的，G ++，OpenSSL的，Apache2的-dev的，libsqlite3 -dev，中的libreadline5-DEV）
安裝紅寶石：rvm install 1.9.2; rvm use 1.9.2 --default
安裝乘客（對於用Apache使用）：rvm gem install passenger
裴ld Apache Passenger mod：passenger-install-apache2-module

請注意，我在這裏實際上有一個無關的問題：它沒有依賴檢查openssl。我發現只執行ruby -e 'require "openssl"'導致錯誤。因此，按照我在http://www.ruby-forum.com/topic/90083#175543找到的說明解決了src/ruby-1.9.2-p290/ext/openssl/中的問題，然後乘客模塊安裝成功。
決定，因爲我打算在測試3.1創建Rails3中一個寶石：rvm use --create [email protected]rails3
安裝導軌：rvm gem install rails

這一切似乎去順利（除從一對夫婦的警告ri和RDoc一代）。但是，現在如果我型rails（後新的shell登錄），我只是得到：

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

不過，我的路徑是：

/usr/local/rvm/gems/[email protected]/bin:/usr/local/rvm/gems/[email protected]/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說：

    IRBRC:  "/usr/local/rvm/rubies/ruby-1.9.2-p290/.irbrc" 
    RUBYOPT:  "" 
    gemset:  "rails3"

所以，我對Rails/Ruby/Ubuntu Gurus的問題是：這裏發生了什麼？如果我只是需要添加一些東西到我的PATH允許bash找到rails，我無法弄清楚什麼。執行以下命令查找在/ usr /本地/ -name RVM軌道的結果是：

/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/gems/rails-3.0.9/bin/rails 
/usr/local/rvm/gems/ruby-1.9.2-p290/gems/activerecord-3.0.9/lib/rails 
/usr/local/rvm/gems/ruby-1.9.2-p290/gems/railties-3.0.9/lib/rails 
/usr/local/rvm/gems/ruby-1.9.2-p290/gems/railties-3.0.9/lib/rails/generators/rails 
/usr/local/rvm/gems/ruby-1.9.2-p290/gems/railties-3.0.9/lib/rails/generators/rails/app/templates/script/rails 
/usr/local/rvm/gems/ruby-1.9.2-p290/gems/actionmailer-3.0.9/lib/rails

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

但試圖直接執行/usr/local/rvm/gems/ruby-1.9.2-p290/bin/rails只是給：

/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/rubies/ruby-1.9.2-p290/lib/ruby/site_ruby/1.9.1/rubygems/dependency.rb:256:in `to_spec' 
    from /usr/local/rvm/rubies/ruby-1.9.2-p290/lib/ruby/site_ruby/1.9.1/rubygems.rb:1195:in `gem' 
    from /usr/local/rvm/gems/ruby-1.9.2-p290/bin/rails:18:in `<main>'

（我不知道，如果這是連一件合理的事嘗試）以防萬一我沒有提供足夠的信息:)

- rvm gem list給出：

任何幫助或指針非常感謝。與此同時，我會繼續爲此感到震驚。

爲什麼你使用'RVM創業板安裝rails'和'RVM寶石list'？不用'rvm'就可以試試'gem install rails'。並顯示你的'rvm list'，'rvm gemset list' –

@nash - 我爲什麼要用'rvm gem install rails'？ - 因爲我不知道我在做什麼:)但是 - 你是對的。我剛剛運行了'gem install rails'，它再次完成了整個安裝，現在我可以訪問'rails'命令。它安裝在'/ usr/local/rvm/gems/ruby-1.9.2-p290 @ rails3/bin /'中，所以我不知道以前安裝的位置或如何清理。目前它的工作原理，所以我會留下它:)好點。如果你創建的答案是「使用'gem install rails'而不是'rvm gem install rails'」，我會將其標記爲答案。 – DavidJ

使用gem install rails代替rvm gem install rails
