Ruby on Rails - 不兼容的 marshal 文件格式 [英] Ruby on Rails - incompatible marshal file format

问题描述

我最近将 Rails v3.x 应用程序升级到 Rails 4.1.1，大部分情况似乎都在转换，但是当我在 apache 配置文件中将应用程序从生产切换到开发时，我收到错误消息 我们很抱歉，但出了点问题 我知道开发环境正在运行，因为我可以在 development.log 文件中看到正在处理的 GET 请求.但在 GET 请求后不久，我在日志中得到以下内容

I recently upgraded a Rails v3.x app to Rails 4.1.1 and everything seemed to transition for the most part, but however when I switch the app from production to development in the apache config file, I get the error message We're sorry but something went wrong I know the development environment is working because I can see the GET request being processed in the development.log file. But shortly after the GET request I get the following in the log

ActionView::Template::Error(不兼容的 marshal 文件格式(无法读取)需要格式 4.8 版；123.34 给出):

推荐答案

就我而言，这个错误是由我在 config\initializers\cookies_serializer 中使用新的 cookies_serializer 选项引起的.rb.

In my case, this error was caused by me playing with the new cookies_serializer option in config\initializers\cookies_serializer.rb.

在开发中，我将其设置为 :json(这意味着我的本地 cookie 被序列化为 json)，但随后我完全删除了该选项并将其投入生产.如果我再次在开发中运行服务器，我的 json 序列化 cookie 会导致相同的错误.

In development I set it to :json (which meant that my local cookies were serialized as json) but then I removed the option completely and put it in production. If I then ran the server in development again my json serialized cookies resulted in the same error.

因此，如果您曾经将 cookies_serializer 设置为 :hybrid 或 :json 运行，那么您将需要继续运行 (at最少) :hybrid.

So if you have ever run with cookies_serializer set to :hybrid or :json then you will need to carry on running with (at least) :hybrid.
