Question

Screenshot of error message on Heroku dashboard.

这里是日志（我对此非常陌生，所以我在下半部分修改了一些看似私密的内容）：

-----> Using set buildpack heroku/ruby

       Bundler will do a full resolve so native gems are handled properly.
       This may result in unexpected gem versions being used in your app.
       In rare occasions Bundler may not be able to resolve your dependencies at all.

       Your Gemfile lists the gem rest-client (>= 0) more than once.
       You should probably keep only one of them.
       While it's not a problem now, it could cause errors if you change the version of just one of them later.

Answer 1

来自Heroku docs：

这意味着您的应用程序正在尝试作为rake资产的一部分连接到数据库：预编译。由于环境中不存在配置变量，因此我们使用占位符DATABASE_URL来满足Rails。

要解决此问题，请确保config/application.rb中显示以下行：

# config/application.rb
config.assets.initialize_on_precompile = false

添加后，提交您的更改并重新部署到Heroku - 您的资产应该在没有您的应用程序尝试连接到数据库的情况下编译，这应该可以解决您目睹的错误。

<强>更新：

your stacktrace的第46行包含以下消息：Devise.secret_key was not set.

According致Devise的作者José Valim，可以通过以下方式解决此问题：

请将以下内容添加到您的Devise初始化程序中：

config.secret_key =＆＃39; - 密钥 - ＆＃39;

或，the following solution似乎适用于多个用户：

我去了我的routes.rb文件并注释掉了devise_for：installs
这一行
然后我回去并重新设计了rails generate：install。如果这不起作用，请使用以前版本的设计，编辑Gemfile对Devise的引用，如下所示：gem＆＃39; devise＆＃39;，＆＃39; 3.0.3＆＃39;然后按照我上面提到的步骤操作。

Answer 2

我做了ExceptionHandler，这似乎导致了问题......

NoMethodError：ExceptionHandler：Module
的未定义方法`setup'

在ExceptionHandler > 0.4.5中，initializer已被config方法取代：

来自docs：

重要

如果您要升级到0.4.6，则需要删除exception_handler初始化程序。

我们已将加载过程更改为使用Rails应用配置 - 您不再需要exception_handler初始值设定项

您需要从exception_handler复制config/initializers/exception_handler.rb设置并将其放入config/production.rb。

您需要删除 config/initializers/exception_handler.rb

如果您发表评论等我可以聊天

无法部署。 Heroku仪表板显示＆＃34;最新版本失败＆＃34;
