ruby-on-rails - 错误//用法 : rails new APP_PATH [options]//when running 'rails server'

Question

背景资料:

我正在使用 GIT 来获取包含 Ruby 文件的项目的存储库。该项目位于 Mac 主目录下的 SITES 文件夹中。

我有 ruby :1.8.7

我刚刚将 Rails 升级到:3.0.3

我想要完成的只是能够在我已经下载的 GIT 项目的浏览器中呈现 localhost.com:3000，以便我可以在本地处理它。

我运行了命令“rails server”并返回以下消息:

Usage:
  rails new APP_PATH [options]

Options:
      [--skip-gemfile]        # Don't create a Gemfile
  -m, [--template=TEMPLATE]   # Path to an application template (can be a filesystem path or URL)
  -d, [--database=DATABASE]   # Preconfigure for selected database (options: mysql/oracle/postgresql/sqlite3/frontbase/ibm_db)
                              # Default: sqlite3
  -O, [--skip-active-record]  # Skip Active Record files
  -J, [--skip-prototype]      # Skip Prototype files
  -T, [--skip-test-unit]      # Skip Test::Unit files
      [--dev]                 # Setup the application with Gemfile pointing to your Rails checkout
  -r, [--ruby=PATH]           # Path to the Ruby binary of your choice
                              # Default: /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby
  -G, [--skip-git]            # Skip Git ignores and keeps
  -b, [--builder=BUILDER]     # Path to an application builder (can be a filesystem path or URL)
      [--edge]                # Setup the application with Gemfile pointing to Rails repository

Runtime options:
  -f, [--force]    # Overwrite files that already exist
  -s, [--skip]     # Skip files that already exist
  -p, [--pretend]  # Run but do not make any changes
  -q, [--quiet]    # Supress status output

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.

您正在运行 rails server从错误的目录。进入包含您的应用程序的目录并从那里运行命令。例如，如果您运行 rails new thingy ，您必须在 thingy使用时的目录 rails server .
