Question

我在桌面/地图中创建了一个新应用。我没有将它与github或任何东西联系起来，而只是在本地工作。我以前使用过rails的功能而且它工作得很好然而现在我想要在我离开的地方拾取它现在说：

Sachins-MacBook-Pro:maps sachinkaria$ rails s
Usage:
  rails new APP_PATH [options]

Options:
  -r, [--ruby=PATH]                                      # Path to the Ruby binary of your choice
                                                         # Default: /usr/local/rvm/rubies/ruby-1.9.3-p392/bin/ruby
  -b, [--builder=BUILDER]                                # Path to a application builder (can be a filesystem path or URL)
  -m, [--template=TEMPLATE]                              # Path to an application template (can be a filesystem path or URL)
      [--skip-gemfile], [--no-skip-gemfile]              # Don't create a Gemfile
      [--skip-bundle], [--no-skip-bundle]                # Don't run bundle install
  -G, [--skip-git], [--no-skip-git]                      # Skip Git ignores and keeps
  -O, [--skip-active-record], [--no-skip-active-record]  # Skip Active Record files
  -S, [--skip-sprockets], [--no-skip-sprockets]          # Skip Sprockets files
  -d, [--database=DATABASE]                              # Preconfigure for selected database (options: mysql/oracle/postgresql/sqlite3/frontbase/ibm_db/sqlserver/jdbcmysql/jdbcsqlite3/jdbcpostgresql/jdbc)
                                                         # Default: sqlite3
  -j, [--javascript=JAVASCRIPT]                          # Preconfigure for selected JavaScript library
                                                         # Default: jquery
  -J, [--skip-javascript], [--no-skip-javascript]        # Skip JavaScript files
      [--dev], [--no-dev]                                # Setup the application with Gemfile pointing to your Rails checkout
      [--edge], [--no-edge]                              # Setup the application with Gemfile pointing to Rails repository
  -T, [--skip-test-unit], [--no-skip-test-unit]          # Skip Test::Unit files
      [--old-style-hash], [--no-old-style-hash]          # Force using old style hash (:foo => 'bar') on Ruby >= 1.9

Runtime options:
  -f, [--force]                    # Overwrite files that already exist
  -p, [--pretend], [--no-pretend]  # Run but do not make any changes
  -q, [--quiet], [--no-quiet]      # Suppress status output
  -s, [--skip], [--no-skip]        # Skip files that already exist

Rails options:
  -h, [--help], [--no-help]        # Show this help message and quit
  -v, [--version], [--no-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.

    You can specify extra command-line arguments to be used every time
    'rails new' runs in the .railsrc configuration file in your home directory.

    Note that the arguments specified in the .railsrc file don't affect the
    defaults values shown above in this help message.

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.

请注意我在正确的目录中，我之前已经启动了服务器。

Answer 1

你在哪个目录？除非文件rails server位于同一目录中，否则正在运行config.ru将返回您粘贴的语法横幅。

Answer 2

如果您正在使用Rails 4+，请重新生成应用的bin/目录可执行文件：

rake rails:update:bin

这些版本与任何其他源代码一样，而不是使用bundler按需生成的存根。使用重新生成的可执行文件可以解决问题。

Rails服务器无法正常工作（即使我在正确的目录中）
