Question

我正在尝试将我的Rails 4应用程序部署到Heroku，当我输入时：

git push heroku master

我收到以下错误：

-----> Preparing app for Rails asset pipeline
       Running: rake assets:precompile       
       rake aborted!
       could not connect to server: Connection refused
       Is the server running on host "127.0.0.1" and accepting
       TCP/IP connections on port 5432?

来自Rails Asset Pipeline on Heroku Cedar：

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。由于配置变量不存在于环境中，而这是Heroku用于配置数据库连接的机制，因此该命令失败。

页面建议我运行

env -i GEM_PATH=$GEM_PATH \
   PATH=$PATH \
   DATABASE_URL=postgres://user:pass@127.0.0.1/dbname \
   /bin/sh -c 'bundle exec rake --trace  assets:precompile'

当我这样做时，我收到以下错误：

产生此错误的原因是什么？我该如何解决？

Answer 1

我不熟悉 user-env-compile ，但只是按照here所述设置了Devise键：

heroku config:set DEVISE_SECRET_KEY=whatever_the_key_is

确保您的初始值设定项使用如下所示的键：

config.secret_key = ENV['DEVISE_SECRET_KEY']

然后像这样禁用 user-env-compile ：

heroku labs:disable user-env-compile -a myapp

然后尝试部署。
