Ruby on Rails配置

Question

我使用以下指南開始使用ubuntu 9.10的導軌。 http://guides.rails.info/getting_started.html

我已經安裝了紅寶石和寶石。

gokul @ gokul-laptop：〜$ ruby​​ -v ruby​​ 1.8.7（2009-06-12 patchlevel 174）[i486-linux] gokul @ gokul-laptop：〜$ gem -v 1.3.6 gokul @ gokul-laptop：〜 $

似乎沒有給出任何回應。 因此使用了突觸軟件包管理器進行安裝。 而且它似乎已正確安裝。

gokul @ gokul-laptop：〜$ rails用法：/ usr / bin / rails / path / to / your / app [options]

選項：-r，--ruby = path所選Ruby二進制文件的路徑（否則腳本使用env，調度程序為當前路徑）。

                                 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)

描述：“ rails”命令創建一個新的Rails應用程序，該應用程序在您指定的路徑上具有默認目錄結構和配置。

示例：rails〜/ Code / Ruby / weblog

This generates a skeletal Rails installation in ~/Code/Ruby/weblog.
See the README in the newly created application to get going.

希望有人可以幫助我...

Answer 1

要運行服務器，請輸入：

./script/server

別：

rails server

rails在當前目錄中創建新的Rails項目。

Answer 2

如果您想在Ubuntu 9.10上開始使用穩定版本的Rails，我建議：

刪除通過apt，aptitude或synaptic安裝的所有寶石，並檢查rubygems至少在1.3.5版中。

 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

---

如果您想學習Rails 3（當前為beta3）

刪除通過apt，aptitude或synaptic安裝的RUBYGEMS軟件包，並手動安裝RubyGems 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 3

安裝捆綁器並生成Rails應用程序后，需要在啟動前將CD插入Rails應用程序

bundle install

步驟如下：

gem install bundler
rails blog
cd blog
bundle install

Answer 4

如果您仍然遇到問題...請嘗試使用這個bundle init。 這將創建GemFile。
