戈庫爾@戈庫爾-筆記本電腦：〜$軌 用法：在/ usr/bin中/導軌/路徑/到/你/應用[選項]

選項： -r，--ruby =路徑到您選擇的Ruby二進制文件的路徑（否則腳本使用env，調度程序當前路徑）。

        Default: /usr/bin/ruby1.8 
-d, --database=name    Preconfigure for selected database (options: mysql/oracle/postgresql/sqlite2/sqlite3/frontbase/ibm_db). 
           Default: sqlite3 
-D, --with-dispatchers   Add CGI/FastCGI/mod_ruby dispatches code to generated application skeleton 
           Default: false 
    --freeze      Freeze Rails in vendor/rails from the gems generating the skeleton 
           Default: false 
-m, --template=path    Use an application template that lives at path (can be a filesystem path or URL). 
           Default: (none) 

Rails的信息：

-v, --version     Show the Rails version number and quit. 
-h, --help      Show this help message and quit. 

常規選項：

-p, --pretend     Run but do not make any changes. 
-f, --force      Overwrite files that already exist. 
-s, --skip      Skip files that already exist. 
-q, --quiet      Suppress normal output. 
-t, --backtrace     Debugging: show backtrace on errors. 
-c, --svn      Modify files with subversion. (Note: svn must be in path) 
-g, --git      Modify files with git. (Note: git must be in path)

，希望有人可以幫我這個...

Answer 1

如果你想開始在Ubuntu 9.10的Rails的穩定版本，我建議：

刪除通過apt，或者一樣安裝任何寶石和檢查RubyGems是至少在1.3.5版本。

gem -v 
sudo gem install sqlite3-ruby rails # will install Rails 2.3.5 = latest stable release 
rails app 
cd app 
rake db:create 
script/server 

---

如果你想手動學習Rails 3中（目前beta3版）

刪除通過apt，或者一樣安裝RubyGems包並安裝RubyGems的1.3.6。

wget http://production.cf.rubygems.org/rubygems/rubygems-1.3.6.tgz 
tar xfz rubygems*tgz 
cd rubygems-* 
sudo ruby setup.rb && cd .. 
gem -v 
# if gem command fails 
sudo ln -s /usr/bin/gem1.8 /usr/bin/gem 

sudo gem install sqlite3-ruby bundler rails -pre 
# will install Rails 3.0.0beta3 
rails app 
cd app 
bundle install 
rake db:create 
rails server 

Answer 2

安裝捆綁和應用的啓動

bundle install 

步驟之前生成的Rails應用程序，你需要cd到軌之後有：

gem install bundler 
rails blog 
cd blog 
bundle install 

Answer 3

要運行服務器類型：

./script/server 

不要：

rails server 

rails在當前目錄中創建新的Rails項目。

Answer 4

如果你仍然有問題...只是嘗試這個包初始化。這將創建GemFile。
