在 dokku 上预部署命令失败

Question

我的app.json看起来像这样

{
    "scripts": {
      "dokku": {
        "predeploy": "poetry run python manage.py collectstatic --noinput && poetry run python manage.py migrate"
      }
    }
}

它给出了这个错误

 !     Predeploy command declared: 'poetry run python manage.py collectstatic --noinput && poetry run python manage.py migrate'
remote: execution of 'poetry run python manage.py collectstatic --noinput && poetry run python manage.py migrate' failed!

       The above exception was the direct cause of the following exception:

           ) from exc
       ImportError: Couldn't import Django. Are you sure it's installed and available on your PYTHONPATH environment variable? Did you forget to activate a virtual environment?

老实说，不确定要多尝试什么。

Answer 1

您看到的是 virtualenv 未激活。这很奇怪，因为诗歌应该处理这个问题。

但是，一方面，heroku 不支持诗歌。

您可以使用这个构建包： https://elements.heroku.com/buildpacks/moneymeets/python-poetry-buildpack

根据文档，collectstatic 应该在部署期间自动发生： https://devcenter.heroku.com/articles/django-assets#collectstatic-during-builds

最后：poetry buildpack 仅创建一个 requirements.txt，然后由 reqular heroku python buildpack 使用 pip 安装。
