我正在开发一个使用rails 2.3.2的应用程序。
当我输入命令"rails script/server"时,我得到了以下输出,而不是启动服务器,为什么?
rails script/server
Usage:
rails new APP_PATH [options]
Options:
-J, [--skip-javascript] # Skip JavaScript files
[--dev] # Setup the application with Gemfile pointing to your Rails checkout
[--edge] # Setup the application with Gemfile pointing to Rails repository
-G, [--skip-git] # Skip Git ignores and keeps
-m, [--template=TEMPLATE] # Path to an application template (can be a filesystem path or URL)
-b, [--builder=BUILDER] # Path to a application builder (can be a filesystem path or URL)
[--old-style-hash] # Force using old style hash (:foo => 'bar') on Ruby >= 1.9
[--skip-gemfile] # Don't create a Gemfile
-d, [--database=DATABASE] # Preconfigure for selected database (options: mysql/oracle/postgresql/sqlite3/frontbase/ibm_db/jdbcmysql/jdbcsqlite3/jdbcpostgresql/jdbc)

-s, [--skip] # Skip files that already exist
-f, [--force] # Overwrite files that already exist
-p, [--pretend] # Run but do not make any changes
Rails options:
-h, [--help] # Show this help message and quit
-v, [--version] # Show Rails version number and quit
Description:
The 'rails new' command creates a new Rails application with a default
directory structure and configuration at the path you specify.
Example:
rails new ~/Code/Ruby/weblog
This generates a skeletal Rails installation in ~/Code/Ruby/weblog.
See the README in the newly created application to get going.
当我输入 Linux 命令 "ls" 后,我会看到以下目录和文件显示:
app Capfile config criptq db doc features Gemfile Gemfile.lock generate lib log nbproject public Rakefile README script spec test tmp vendor
我的Gemfile如下:
source "http://rubygems.org"
gem "rails", "2.3.2"
gem "mysql", "2.8.1"
gem "fastercsv"
gem "will_paginate", "2.3.16"
gem "chronic", "0.6.4"
gem "whenever", "0.4.1"
gem "searchlogic", "2.4.28"
group :development do
gem "mongrel", "1.1.5"
end
group :test do
gem "rspec", "1.3.2"
gem "rspec-rails", "1.3.4"
gem "factory_girl", "1.3.3"
end
