为什么我得到！ [remote rejected] master -> master (pre-receive hook declined) in dokku

Question

我需要帮助。我正在尝试将我的 Python/Flask 应用程序部署到 Dokku 服务器，但出现错误并且我不知道如何修复它。这是 git 遥控器：

dokku   dokku@apps.danieldiaz.me:portfolio (fetch)
dokku   dokku@apps.danieldiaz.me:portfolio (push)

该应用程序是在服务器上创建的，但是当我创建一个：

git push dokku

或：

git push dokku master

我收到这个错误：

To apps.danieldiaz.me:portfolio
 ! [remote rejected] master -> master (pre-receive hook declined)
error: failed to push some refs to 'dokku@apps.danieldiaz.me:portfolio'

域 apps.danieldiaz.me 有效，我可以通过 ssh 连接。

Answer 1

无法检测到您的 python 依赖项，因此 Dokku 无法 select python buildpack。你需要有一个 requirements.txt 表示你在你的 repo 根目录中的依赖关系来解决这个问题。
