Dokku 部署问题 - “setuidgid: fatal: 无法运行 Gunicorn: 文件不存在”

Question

我在尝试部署我的项目时遇到了 Dokku 的部署问题。该错误消息表明gunicorn 存在问题，但我无法找出根本原因。详情如下：

错误信息：

remote: perl: warning: Falling back to a fallback locale ("en_US.UTF-8").
       Attempting pre-flight checks (web.1)
-----> Executing 2 healthchecks
       Running healthcheck name='default' type='uptime' uptime=10

To id_adress:myproject
 ! [remote rejected] main -> main (pre-receive hook declined)
error: failed to push some refs to 'id_adress:myproject'

失败似乎与找不到gunicorn文件有关。

我已检查 Dokku 文档并确保必要的配置已到位。 我使用了这个建议和这个建议，但我仍然有同样的问题。

有人在 Dokku 部署和 Gunicorn 进程方面遇到过类似的问题吗？我可以采取哪些步骤来排查和解决此问题？ 任何见解或指导将不胜感激。谢谢！

更新： 原来我需要在 Procfile 中写入

web: gunicorn config.wsgi --log-file -

相关应用程序可能是基于构建包的应用程序。构建包由 herokuish 基础镜像 按特定顺序运行，第一个检测到的镜像即为所应用的镜像。

如果没有更多日志信息（部署的第一部分已在发布的日志中删除），很可能会检测到多个构建包，其中 python 构建包 - 它将在

requirements.txt

中安装依赖项 - 不是第一个。您可能希望通过创建

.buildpacks

文件并将其提交到存储库的基础来使用多个构建包，并指定您需要的每个构建包的内容。下面是指定justheroku/python buildpack的示例。

heroku/python

您还可以通过 buildpacks 命令设置构建包:

dokku buildpacks:add node-js-app heroku/python

这将代表您管理

.buildpacks

文件。
