我在自己的数据库上进行了一些本地迁移,当我尝试在heroku上迁移时,它终止了我的终止:
Multiple migrations have the name CreateUsers
/app/vendor/bundle/ruby/2.0.0/gems/activerecord-4.0.2/lib/active_record/migration.rb:978:in `validate'

Tasks: TOP => db:migrate
(See full trace by running task with --trace)
我试过heroku pg:重置DATABASE并再次迁移,仍然给我这个错误
在本地运行数据库似乎没问题。有什么建议吗?

This Multiple migrations have the name CreateUsers
看起来您有两次具有相同类名CreateUsers
如果成功,请在本地运行所有migrations
,然后再次尝试重新推送heroku
希望它能解决你/这个问题

我用这种方式解决了这个问题: 1.检查db / migrate文件夹。您将看到至少两个具有相同名称的文件。 2.删除旧文件。使用git rm db / migrate /&#34;文件名&#34; 3.push to git
$git add -A
$git commit -m ""
$git checkout master
4.赶到远程存储库并部署到Heroku:
$ bundle exec rake test
$ git push
$ git push heroku
$ heroku run rake db:migrate
