django - Heroku Push 导致 django 的 slug-compiler 出现超时错误

Question

我有两个 Heroku 应用程序，登台和生产。我能够毫无问题地将最新代码推送到登台服务器，但是当我尝试将最新代码推送到生产环境时，出现超时错误。

看看人们遇到的类似错误，听起来这可能是需求文档或其中一个包的问题。但我不确定如何开始调试。我们使用了很多外部包。事实上，它可以在一个 Heroku 应用程序上运行，但不能在另一个应用程序上运行，这一事实让我想知道它到底有多少是以前的应用程序。

据我所知，它似乎在该过程中的不同时间超时，没有任何其他错误。第一次在开始安装 psycopg2 后超时，但最后一次它通过 psycopg2，然后在 gevent 安装时超时。

我很茫然，这是我第一次遇到这个问题，这个版本需要尽快发布。有人有什么想法吗？

这里是 stackoverflow 允许我发布的尽可能多的日志:

Answer 1

现在有一个正确但未记录的解决方案来解决这个问题(github 历史记录显示它于 2013 年 2 月实现):COMPILE_TIMEOUT 环境变量。将其设置为 50 分钟超时(默认值为“900”，即 15 分钟):

$ heroku config:set COMPILE_TIMEOUT=3000

(注意:您需要user-env-compile启用才能使用此功能)

更新:请阅读 this answer 上的评论对于一个重要的更新——长话短说，Heroku 建议在这些情况下直接联系支持人员，而 COMPILE_TIMEOUT 要么不再有效，要么从未作为此特定问题的解决方案起作用。
