django - Pipenv 无法在远程服务器 (Heroku) 上安装 boto3

Question

我成功部署了我的 django 项目，然后我想使用 AWS S3 来提供静态文件。所以我安装了所需的软件包，一切都在本地运行。但是现在当我尝试时 git push heroku master它因以下回溯而失败:

以前我在尝试在本地安装 psycopg2 时遇到了类似的问题，但经过多次尝试后，除了解决方法(改为安装 psycopg2-binary)外，仍然没有找到任何东西。所以在这里我也觉得有点绝望。我试过 pipenv sync , pipenv update ，最终我用一个新的 venv 重新启动，但它没有帮助。如果我尝试通过 heroku 的 bash 安装 boto3，它会起作用。但这并不能解决问题，因为文件已被锁定。

django-storages 依赖于 1.4.4 及更高版本的 boto3 版本，但 pipenv 安装了 3 月 28 日发布的 1.12.31。所以 heroku 和 pypi.org 之间可能存在缓存不匹配。所以你可以通过使用以下命令手动安装 boto3 来降级 boto3
pipenv install "boto=1.4.4"
我指定了 1.4.4，因为它是 django-storages 所需的最低版本。但是您可以安装 1.4.4 以上的任何版本。
