无法将Phoenix 1.3.0-rc1部署到Heroku，生成但崩溃

我正在尝试将Phoenix 1.3.0-rc1部署到Heroku

它构建正确，但我无法访问该网站。请注意，在我的机器上运行Phoenix时，我可以访问该应用程序，这可能会很有用

还值得注意的是，我正在使用SSL

这是

$heroku日志--tail

非常感谢您的帮助。

我遇到了同样的错误，原来phoenix 1.3.0-rc1需要elixir 1.4。如果您添加一个

elixir\u buildpack.config

，您可以如下设置elixir版本：

elixir_version=1.4.2

我在这里找到了这个解决方案：
