rails 3，爲什麼我不能在ubuntu上使用命令行？

我在Ubuntu 11.10上運行RubyMine 4，RubyMine內部的每件事情都很好，我可以運行服務器，開發等。但是，當我需要在命令行上工作時，我無法做任何事情。rails 3，爲什麼我不能在ubuntu上使用命令行？

我cd到我的應用程序目錄，然後我想：

$ rails s

我得到：

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

這是奇怪的是，爲什麼它沒有安裝，而我可以在RubyMine的正常工作IDE！

我需要使用命令行卸載寶石，發現我不能使用命令行，因爲它應該..

[email protected]:~/Documents/RoR/course_builder$ gem uninstall 'capybara-firebug' 
ERROR: While executing gem ... (Gem::InstallError) 
    cannot uninstall, check `gem list -d capybara-firebug`

$ gem list -d會給我：

*** LOCAL GEMS ***

沒有寶石有..

如果I型：

$ bundle install

我得到：

/usr/lib/ruby/vendor_ruby/bundler/rubygems_ext.rb:8:in `require': no such file to load -- rubygems (LoadError) 
    from /usr/lib/ruby/vendor_ruby/bundler/rubygems_ext.rb:8 
    from /usr/lib/ruby/vendor_ruby/bundler.rb:11:in `require' 
    from /usr/lib/ruby/vendor_ruby/bundler.rb:11 
    from /usr/bin/bundle:4:in `require' 
    from /usr/bin/bundle:4

雖然bundle install內的RubyMine工作正常

所以，我很想念這裏！？爲什麼我不能使用命令行..？

這裏是我的寶石環境：

如果鍵入RVM，我得到：

= rvm 

    * http://github.com/wayneeseguin/rvm 

    == DESCRIPTION: 

    RVM is the Ruby enVironment Manager (rvm). 
    It manages Ruby application environments and switching between them. 

    == Usage 

     rvm [Flags] [Options] Action [Implementation[,Implementation[,...]] 

    == Flags 

     --default  - with 'rvm use X', sets the default ruby for new shells to X. 
     --debug  - Toggle debug mode on for very verbose output. 
     --trace  - Toggle trace mode on to see EVERYTHING rvm is doing. 
     --force  - Force install, removes old install & source before install. 

....

如果我輸入ruby -v

ruby 1.8.7 (2011-06-30 patchlevel 352) [i686-linux]

輸入「rvm」是幹什麼的？ ruby -v怎麼樣？ – sunnyrjuneja 2012-02-28 04:12:00

請參閱上面的rvm結果編輯，ruby -v結果 – simo 2012-02-28 04:19:51

您是否真的安裝了rvm？你是否在命令行上使用xxxx來選擇你的Ruby和gemset？ – 2012-02-28 04:23:25

我不相信您的rvm已正確設置。爲了簡單起見，我們從一開始就按照這裏的步驟開始：

http://beginrescueend.com/rvm/install/

安裝在命令行。

user$ bash -s stable < <(curl -s https://raw.github.com/wayneeseguin/rvm/master/binscripts/rvm-installer)

打開您的主目錄中的.bashrc文件夾。

user$ vim .bashrc

編輯和添加：

[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm" # Load RVM function

來源的。bashrc文件並關閉終端

user$ source ~/.bashrc 
user$ exit

重新打開終端並檢查rvm是否正常工作。

user$ type rvm | head -1

如果返回

rvm is a function

我們是很好的。檢查您是否具備所有先決條件：

rvm requirements

根據需要進行安裝。選擇你最喜歡的紅寶石的味道（它似乎是1.8.7，如果是的話，請按照確切的命令或將其替換爲您的選擇）。

rvm install 1.8.7

當其完成後，

rvm use 1.8.7 --default

如果沒有工作，請通過運行

which ruby

謝謝Sunny，我已經解決了這個問題，我應該在做任何事之前先使用gemset！對不起，但是，我是新手到RVM .. – simo 2012-02-29 11:04:20

嘗試做任何rails - 相關運行之前，在命令行中/bin/bash --login更新後東東。如果有效，請在您打開的每個新命令行中再次執行此操作。
