Question

我克隆了一个Rails 4.2.0应用程序（github.com/hackcentral/hackcentral），然后我去运行了“rails server＆＃39;”，但是我收到了默认的not-in-Rails-application错误消息（下面输出）。有什么建议吗？

Usage:
  rails new APP_PATH [options]

Options:
  -r, [--ruby=PATH]                                      # Path to the Ruby binary of your choice
                                                         # Default: /Users/jon/.rbenv/versions/2.2.0/bin/ruby
  -m, [--template=TEMPLATE]                              # Path to some application template (can be a filesystem path or URL)
      [--skip-gemfile], [--no-skip-gemfile]              # Don't create a Gemfile
  -B, [--skip-bundle], [--no-skip-bundle]                # Don't run bundle install
  -G, [--skip-git], [--no-skip-git]                      # Skip .gitignore file
      [--skip-keeps], [--no-skip-keeps]                  # Skip source control .keep files
  -O, [--skip-active-record], [--no-skip-active-record]  # Skip Active Record files
  -S, [--skip-sprockets], [--no-skip-sprockets]          # Skip Sprockets files
      [--skip-spring], [--no-skip-spring]                # Don't install Spring application preloader
  -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
      [--skip-turbolinks], [--no-skip-turbolinks]        # Skip turbolinks gem
  -T, [--skip-test-unit], [--no-skip-test-unit]          # Skip Test::Unit files
      [--rc=RC]                                          # Path to file containing extra configuration options for rails command
      [--no-rc], [--no-no-rc]                            # Skip loading of extra configuration options from .railsrc file

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.

我刚刚克隆了那个回购并遇到了同样的问题。看起来他们没有推送他们的bin目录，这就是为什么rails命令没有按预期工作的原因。要修复，只需cd进入目录并运行以下

rake rails:update:bin

这将创建bin目录以及相关文件。干杯！

Rails无法识别Rails目录
