phương pháp xác định 'tên' cho 'ActionMailer': String

Question

Tôi đã một phiên bản cũ của dự án Rails được xây dựng sử dụng BrowserCMS trong file config/môi trường

RAILS_GEM_VERSION = '2.3.4' unless defined? RAILS_GEM_VERSION 

vì vậy tôi cài đặt đá quý này sử dụng để RVM tôi có thể chạy nó

$ gem list 

*** LOCAL GEMS *** 

actionmailer (2.3.8, 2.3.4) 
actionpack (2.3.8, 2.3.4) 
activerecord (2.3.8, 2.3.4) 
activeresource (2.3.8, 2.3.4) 
activesupport (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) 

tôi chạy rake db:create nó hoạt động tốt, nhưng khi tôi chạy rake db:migrate tôi đã nhận lỗi này

rake aborted! 
undefined method `name' for "actionmailer":String 

tôi đã cố gắng sử dụng vết nhưng tôi đã không nhận được bất cứ điều gì có thể giúp

$ rake db:migrate --trace

bất kỳ sự giúp đỡ xin vui lòng?

Answer 1

Tôi nghĩ bạn nên cập nhật phiên bản RubyGems.
Hãy thử gem install rubygems-update.

Answer 2

Tôi gặp sự cố này. Giải pháp là hạ cấp rubygems xuống phiên bản bạn hỗ trợ.

tôi cần phiên bản 1.3.5 (đối với đường ray 2.3.5)

Vì vậy, bạn cần thực hiện:

gem install rubygems động cập nhật -v 1.3.5

update_rubygems - version = 1.3.5

Và bây giờ rake sẽ hoạt động.
