脱机生成错误 - Django压缩机

Question

我试图通过Flynn设置Cabot，这基本上就像一个内部的heroku。 当我部署eveything并尝试运行它时，我得到这个异常。

OfflineGenerationError: You have offline compression enabled but key "88dbbdf7c5e6ceca63a19023be40a840" is missing from offline manifest. You may need to run "python manage.py compress". 

我读here对于COMPRESS_ROOT路径可能不是绝对的，这可能是问题，但是当我检查，我在日志中得到这些。对我来说似乎绝对。

[2017-07-28T13:50:24.4Z] ('\n \n \n \n STATIC & CCOMPRESS ARE ', '/app/cabot/collectedstatic/', '\n \n \n \n ') 
[2017-07-28T13:50:24.532943Z] ('\n \n \n \n STATIC & CCOMPRESS URL ARE ', '/static/', '\n \n \n \n ') 

我试着在构建过程中运行manage.py compress并得到以下错误。

当我跑manage.py压缩

奇怪的是，如果我对我的本地搬运工运行它，它完美地运行。我试图在这里抛弃docker部分并使用procfile使用heroku像构建过程一样运行。 不知道解决方案可能是什么。

Docker和Heroku都会有不同的基础机器。我相信你不是在Heroku上部署容器，而是在VM上部署容器，并且你正在Docker上进行本地测试。他们都不同。

假设在两种情况下的包管理apt，你应该在两个地方执行命令

apt list --installed 

，看看哪些包丢失了在Heroku。这将让你和这个问题的想法。
