Question

当我尝试生成安装了Rails 3.0.6或3.0.7的新应用程序时，我只是获取使用rails命令的说明。出于某种原因，Rails似乎认为我输入了错误的语法（我当然没有）。但是，一切都在3.0.5或更低的情况下正常工作。我运行Ruby 1.9.2和Ubuntu 10.04。

rails new app

将导致：

Usage:
  rails new APP_PATH [options]

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

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

Rails options:
  -v, [--version]  # Show Rails version number and quit
  -h, [--help]     # Show this help message 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.

Answer 1

尝试更新rubygems;

$ gem update --system

Answer 2

似乎正在运行rvm rubygems current打破了这一点，至少对我而言。我按照提到的here运行命令，它将删除所有弃用警告，运行gem update --system修复它，并带回弃用警告。
