Rails，部署到Heroku后:无法运行控制台，db:migrate [英] Rails, post-deploy to Heroku: unable to run console, db:migrate

问题描述

美好的一天，

我和我的团队正尝试将我们的Rails应用程序推送到Heroku-git push heroku dev:master成功，但是此后heroku run rails db:migrate，heroku run rails console等都失败，并出现以下错误(完整的跟踪信息粘贴在帖子底部) :

My team and I are trying to push our Rails app to Heroku - git push heroku dev:master is successful, but thereafter heroku run rails db:migrate, heroku run rails console, etc. all fail with the following error (full trace pasted at bottom of post):

   NoMethodError: undefined method `map' for nil:NilClass
    /app/vendor/bundle/ruby/2.4.0/gems/warden-jwt_auth-0.3.6/lib/warden/jwt_auth.rb:89:in `upcase_first_items'

我在宝石jwt_auth的文件中找到了失败的方法upcase_first_items，但仍然无法解决.在Google上搜索错误(包括错误的迭代)会显示0条结果.

I tracked down the failing method upcase_first_items in the files of the gem jwt_auth, but remain unable to solve this. Searching the error on Google (including iterations of the error) turns up 0 results.

我们已经在两周前成功将该应用程序推送到了Heroku，并且此后未更改身份验证方面的任何内容(通过查看过去两周中的所有提交，我已经确定了这一点)

We successfully pushed this app to Heroku two weeks ago, and have not since changed anything with regards to authentication (which I've made sure of by reviewing all our commits from the last 2 weeks).

有什么想法吗?

谢谢， 迈克尔

Update 1

我恢复了前两周(即从现在到最后一次正常部署之间)的每次提交，并进行了部署，但是收到了相同的错误.我什至从之前之前的最后一个部署(正在运行的部署)开始提交提交，并且仍然遇到相同的错误，这使我相信这与最近几周的提交无关.

I reverted to each commit from the previous two weeks (i.e. between now and the last working deploy), and deployed, but received the same error. I reached commits from even before the last deploy (the deploy that was working), and still have the same error, which leads me to believe it has nothing to do with our commits from the last few weeks.

当我进入Heroku仪表板并将构建从两周前恢复到部署时，Rails命令(heroku运行rails c，heroku运行rails db:migrate等)再次起作用.

When I went to the Heroku dashboard and reverted the build to the deploy from two weeks ago, the Rails commands (heroku run rails c, heroku run rails db:migrate, etc.) once again work.

推荐答案

可能有人将dry-configurable gem从版本0.9.0升级到了0.11.1.这个gem是warden-jwt_auth的依赖项，而它是devise-jwt的依赖项，新版本将其破坏.

Probably someone or something upgraded the dry-configurable gem from version 0.9.0 to 0.11.1. This gem is a dependency of warden-jwt_auth which is a dependency of devise-jwt and the new version breaks it.

几天前，版本 0.11.0 dry-configurable的>已发布，并且warden-jwt_auth使用了它，因为它使用~> 0.6指定了此依赖项的版本，其中包括错误的版本(从0.6到1.0的所有内容都可以).您可以在Gemfile.lock或warden-jwt_auth的依赖项中看到它.

A few days ago the version 0.11.0 of dry-configurable was released and warden-jwt_auth uses it, because it specifies the version of this dependency with ~> 0.6, which includes the faulty version (everything from 0.6 to 1.0 would be fine). You can see that in the Gemfile.lock or in the dependencies of warden-jwt_auth.

如果有人确实运行过bundle upgrade，它将拉出新的错误版本.

If somebody did run bundle upgrade it will have pulled the new faulty version.

我建议您将dry-configurable的旧版本固定在Gemfile中:

I recommend you to pin the older version of dry-configurable in your Gemfile:

gem 'dry-configurable', '0.9.0'

然后运行bundle update并再次部署.
