Rails版本7.0.3 Ruby版本3.1.2

Answer 1

当您查看该文件的264-280行时，会发现以下case块：

# this application template only supports Rails version 4.1 and newer
case Rails::VERSION::MAJOR.to_s
when "5"
  say_wizard "You are using Rails version #{Rails::VERSION::STRING}. Please report any issues."
when "3"
  say_wizard "You are using Rails version #{Rails::VERSION::STRING} which is not supported. Use Rails 4.1 or newer."
  raise StandardError.new "Rails #{Rails::VERSION::STRING} is not supported. Use Rails 4.1 or newer."
when "4"
  case Rails::VERSION::MINOR.to_s
  when "0"
    say_wizard "You are using Rails version #{Rails::VERSION::STRING} which is not supported. Use Rails 4.1 or newer."
    raise StandardError.new "Rails #{Rails::VERSION::STRING} is not supported. Use Rails 4.1 or newer."
  end
else
  say_wizard "You are using Rails version #{Rails::VERSION::STRING} which is not supported. Use Rails 4.1 or newer."
  raise StandardError.new "Rails #{Rails::VERSION::STRING} is not supported. Use Rails 4.1 or newer."
end

这个块只检查主要的Rails版本是否是"3"、"4"或"5"。对于所有其他版本号，它将返回您得到的错误消息，无论该数字是否较低(如"2")或更高(如"6"或"7")。

除了这张支票做得不好外，它肯定已经过时了。我建议联系那个文件的维护人员看一看。

或者，您也可以尝试克隆和修复该文件，允许更新版本。但请记住，不能保证该文件将与新版本的开箱即用。需要更改文件以支持更新版本并不是不可能的。
