每当我运行rails generate -h或其任何变体（rails g --help或其他）时，就会发生这种情况。

$ rails generate --help

  rails new APP_PATH [options]

  -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.

这里发生了什么？我的rails安装没有什么特别之处，我刚刚gem install rails和rails new myprojectname然后运行了rails generate --help并获得了rails new --help的输出。

Answer 1

运行后

rails new myprojectname

你应该切换到这个目录

cd myprojectname

您需要在rails项目根文件夹中，以便在其中生成任何内容。

Answer 2

您应该转移到您的应用目录

rails generate -h输出错误的documnetation
