Question

我是Ruby on Rails的新手，目前正在运行Michael Hartl教程。在尝试调用任何方法时，我开始遇到一个疯狂的长错误。没关系哪个。以下是运行：

rails generate controller StaticPages about --no-test-framework

然后我收到以下错误：

我的假设是与我的RVM和我拥有的宝石有关。我知道这是一个很长的错误，很多都是我正在处理的项目所特有的，但是我们非常感谢任何帮助。请记住，我是严肃的菜鸟！

编辑：

require 'securerandom'

def secure_token
token_file = Rails.root.join('.secret')
if File.exist? (token_file)
    #Use the existing token
    File.read token (token_file).chomp
else
    #Generate a new token and store it in token_file.
    token = SecureRandom.hex(64)
    File.write(token_file, token)
    token
end
end

SampleApp::Application.config.secret_key_base = secure_token

Answer 1

将chomp替换为to_s：

File.read token (token_file).to_s

没有方法错误 - 未定义的方法'chomp'
