ruby-on-rails - Rails，后部署到 Heroku : unable to run console, db:migrate

Question

再会，

我和我的团队正在尝试将我们的 Rails 应用程序推送到 Heroku - git push heroku dev:master 成功，但此后 heroku run rails db:migrate 、 heroku run rails console 等都失败并出现以下错误(完整跟踪粘贴在帖子底部):

   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 gem upcase_first_items 的文件中找到了失败的方法 jwt_auth ，但仍然无法解决这个问题。在 Google 上搜索错误(包括错误的迭代)会得到 0 个结果。

两周前我们成功地将这个应用程序推送到 Heroku，并且从那以后没有改变任何关于身份验证的 (我已经通过审查过去两周的所有提交来确定这一点)。

有任何想法吗？

谢谢，
迈克尔

更新 1

我恢复到前两周(即从现在到最后一次工作部署之间)的每次提交，并进行部署，但收到相同的错误。在 上次部署(正在运行的部署)之前，我什至达到了 的提交，但仍然有相同的错误，这让我相信这与我们过去几周的提交无关。

当我转到 Heroku 仪表板并将构建恢复到两周前的部署时，Rails 命令(heroku run rails c、heroku run rails db:migrate 等)再次起作用。

Answer 1

使用 0.8.0 的 devise-jwt 版本不再是问题。请在升级时查看 0.7.0 版本的重大变化。

上一个答案
可能有人或某事将 dry-configurable gem 从 0.9.0 版本升级到 0.11.1 。这个 gem 是 warden-jwt_auth 的一个依赖项，它是 devise-jwt 的一个依赖项，新版本打破了它。
前几天发布了 0.11.0 的 dry-configurable 版本，warden-jwt_auth 使用了它，因为它用 ~> 0.6 指定了这个依赖的版本，其中包含了错误版本(从 0.6 到 1.0 的一切都可以)。您可以在 Gemfile.lock 或 warden-jwt_auth 的依赖项中看到这一点。
如果有人确实运行了 bundle upgrade，它将拉出新的错误版本。
我建议您在 dry-configurable 中固定旧版本的 Gemfile :

gem 'dry-configurable', '0.9.0'

然后运行 ​​ bundle update 并再次部署。
