ruby on rails 配置

Question

我使用以下指南开始使用 ubuntu 9.10 的 rails。 http://guides.rails.info/getting_started.html

我已经安装了 ruby​​ 和 gem。

---

gokul@gokul-laptop:~$ ruby​​ -v ruby 1.8.7 (2009-06-12 补丁级别 174) [i486-linux] gokul@gokul-laptop:~$ gem -v 1.3.6 gokul@gokul-laptop:~$

---

对于轨道，

---

gokul@gokul-laptop:~$sudo gem install rails

---

似乎没有给出任何回应。 所以使用突触包管理器来安装它。而且它似乎已经正确安装了。

---

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

选项： -r, --ruby=path 您选择的 Ruby 二进制文件的路径（否则脚本使用 env，调度程序当前路径）。

                                 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)

轨道信息：

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

常规选项：

-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)

说明： 'rails' 命令创建一个新的 Rails 应用程序，并使用默认值 您指定的路径中的目录结构和配置。

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.

app 文件夹是使用所有正确的文件夹创建的。问题从以下命令开始...

---

gokul@gokul-laptop:~$ sudo gem install bundler

[sudo] gokul 的密码：

成功安装 bundler-0.9.24

已安装 1 个宝石

正在为 bundler-0.9.24 安装 ri 文档...

正在为 bundler-0.9.24 安装 RDoc 文档...

gokul@gokul-laptop:~$ 捆绑安装

找不到 Gemfile

gokul@gokul-laptop:~$

---

来到数据库，默认的sqlite3好像已经安装正确了。

---

gokul@gokul-laptop:~$ sqlite3

SQLite 版本 3.6.16

输入“.help”获取说明

输入以“;”结尾的 SQL 语句

sqlite>

执行以下命令后，在 (http://localhost:3000) 处找不到欢迎登机页面...

希望有人能帮我解决这个问题...

Answer 1

如果您想在 Ubuntu 9.10 上开始使用稳定版本的 Rails，我建议：

删除通过 apt、aptitude 或 synaptic 安装的所有 gem，并检查 ruby​​gems 是否至少为 1.3.5 版。

 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

---

如果你想学习 Rails 3（目前是 beta3）

删除通过 apt、aptitude 或 synaptic 安装的 RUBYGEMS 包并手动安装 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 2

运行服务器类型：

./script/server

不要：

rails server

rails 在当前目录创建新的 Rails 项目。

Answer 3

安装 bundler 并生成 rails 应用程序后，您需要在启动之前 cd 进入 rails 应用程序

bundle install

步骤是：

gem install bundler
rails blog
cd blog
bundle install

Answer 4

如果你仍然遇到问题...试试这个 bundle init 。这将创建 GemFile。
