ruby-on-rails - Ruby on Rails 应用程序无法启动

Question

正如您在https://ssl.virtualweb.at/redmine/上看到的那样，我尝试让 Redmine 启动并运行。

一开始我收到了这个错误：ActiveSupport::Deprecation:Module 的未定义方法 `mattr_accessor'

有人可以这么好，给一些提示如何让它运行吗？

Answer 1

Can you give us a little more information? For example - can you go and look at the logs and find the full backtrace of the error that is occurring? Otherwise we don't know where the error is occurring. Then we can narrow it down a bit better

My best guess atm, though, is that you have the wrong version of ruby or rails or rake (or something similarly important). mattr_acessor is a fundamental method in ruby - so I'd start by reading the redmine docs to see what version of ruby you need.

Then go check if you've got that version installed... repeat with rails, required gems etc.
