升级到Rails 3.1.1之后:"undefined method`javascript_expansions'"错误 [英] After upgrading to Rails 3.1.1: "undefined method `javascript_expansions'" error

问题描述

我已经将Rails从3.0.10升级到3.1.1，现在我收到了以下错误消息:

Ive upgraded rails from 3.0.10 to 3.1.1 and now Im getting the following Error:

undefined method 'javascript_expansions' for ActionView::Helpers::AssetTagHelper:Module

但不是在每个页面上，仅涉及一些页面.我已经用谷歌搜索了，但是什么也没找到！我正在运行ruby 1.9.2 ...

but not on every page, just some pages are involved. I googled it already but I didnt find anything! Im running ruby 1.9.2 by the way...

我的资产管道也似乎不起作用.它不会加载application.css和application.js文件，即使它在assets子文件夹中也是如此.每次尝试获取任何文件时，我都会遇到路由错误.

Also my asset pipeline doesnt seem to work. Its not loading the application.cssand application.js file even its in the assets subfolders. Im getting a routing error each time I try to fetch any of the files.

推荐答案

我解决了此问题，将therubyracer gem添加到Gemfile并运行了bundle install.就这样...

I solved this problem adding the therubyracer gem to the Gemfile and runned bundle install. Thats it...
