如何使用Ruby on Rails运行“ rails s]

Question

我正在学习很长的教程，运行rails s时会得到以下输出。我可以使用rail new。

    Usage:
  rails new APP_PATH [options]

    Options:
          [--skip-namespace], [--no-skip-namespace]              # Skip namespace (affects only     isolated applications)
  -r, [--ruby=PATH]                                          # Path to the Ruby binary of your choice
                                                             # Default: /home/ec2-user/.rvm/rubies/ruby-2.5.5/bin/ruby

                                                             # Default: sqlite3

      [--api], [--no-api]                                    # Preconfigure smaller stack for API only apps

  -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.

我阅读了与此有关的其他问题，但均未解决问题。

我在apps目录中，这是ls输出：

config.ru  Gemfile  Gemfile.lock  Rakefile  README.md

[我看到其他答案都提到了脚本文件夹，但是我没有脚本文件夹。

我也尝试过：rake rails:update:bin并获得此输出：

The dependency tzinfo-data (>= 0) will be unused by any of the platforms Bundler is installing for. Bundler is installing for ruby but the dependency is only for x86-mingw32, x86-mswin32, x64-mingw32, java. To add those platforms to the bundle, run `bundle lock --add-platform x86-mingw32 x86-mswin32 x64-mingw32 java`.

尝试重定向到项目文件夹，然后运行rails s，可能您又回到了一个文件夹。在命令行上键入ls时，应该会看到app / bin / config /。
