未定义的方法'名称'为“actionmailer”：字符串 [英] undefined method `name' for "actionmailer":String

问题描述

 构建了旧版本的Rails项目> RAILS_GEM_VERSION ='2.3.4'除非定义？ RAILS_GEM_VERSION 
  

所以我使用rvm安装了这个gem，这样我就可以运行它了

  $ gem list 
 
 ***本地GEMS *** 
 
 actionmailer（2.3.8,2.3 .4）
 actionpack（2.3.8,2.3.4）
 activerecord（2.3.8,2.3.4）
主动资源（2.3.8,2.3.4）
有效支持（2.3.8,2.3.4）
 bundler（1.1.4）
 mysql（2.8.1）
 rack（1.1.3,1.0.1）
 rails（2.3 .4）
 rake（0.8.7）
  

我运行 rake db：create 它工作正常，但是当我运行 rake db：migrate 时出现此错误

  rake中止！ 
actionmailer的未定义方法`name'：String

有什么帮助吗？

解决方案

我有这个问题。
解决方案是将rubygems降级到您支持的版本。

我需要版本1.3.5（适用于rails 2.3.5）

所以你需要这样做：

gem install ruby​​gems-update -v 1.3.5

update_rubygems --version = 1.3.5

现在耙子应该可以工作。 / p>

I've an old version of Rails project which was built using BrowserCMS in the config/environment file

RAILS_GEM_VERSION = '2.3.4' unless defined? RAILS_GEM_VERSION

so I installed this gems using rvm so I can run it

$ gem list

*** LOCAL GEMS ***

actionmailer (2.3.8, 2.3.4)

any help please?

解决方案

I had this problem. The solution is to downgrade rubygems to a version you support.

I needed version 1.3.5 (for rails 2.3.5)

So you need to do:

gem install rubygems-update -v 1.3.5

update_rubygems --version=1.3.5

And now rake should work.
