我正在使用 ruby​​ on rails 进行狂欢贸易。但是在执行此命令“bundle exec rails g spree_fancy:install”时出现错误。我做错了什么？请帮我。提前致谢。

这是我的错误：

 moududhassan@moududhassan-HP-ProBook-450-G1:~/SpreeProject/banglashop$ bundle exec rails g spree_fancy:install
      append  vendor/assets/javascripts/spree/frontend/all.js
      insert  vendor/assets/stylesheets/spree/frontend/all.css
         run  bundle exec rake railties:install:migrations FROM=spree_fancy from "."
Would you like to run the migrations now? [Y/n] n
Skipping rake db:migrate, don't forget to run it!

bundle exec rails g spree_fancy:install您遇到的错误是因为您的 spree_i18n 迁移没有首先运行。您可以告诉这一点，因为错误消息正在引用翻译表。

您必须修复迁移尝试运行的顺序，以便 spree_i18n 在其他人之前运行，或者在运行迁移之前尝试将 spree_i18n 从 Gemfile 中注释掉。

您在访问 localhost:3000 时看到的错误消息是待处理的迁移错误，因为它说您需要运行rake db:migrate才能运行它们。根据您的情况，您可能还需要rake railties:install:migrations在运行之前rake db:migrate确保将所有扩展迁移都复制到您的应用程序中。
