在Docker容器中"uwsgi进入致命状态，太多开始重试太快“。

Question

我使用Vagrant部署了一个VM，它使用docker创建了2个对接容器。它们都在运行，但是web_sc (webserver容器，web_sc在它的日志中有：uwsgi entered FATAL state, too many start retries too quickly )。由于这个原因，Bad服务器只返回错误502:坏网关。我所做的就是用vagrant up --provision启动它。有人知道怎么修吗？谢谢。

如果使用的是docker，请尝试使用

sail composer clearcache

在那之后

sail composer install
