python - 使用 ElasticBeanstalk 在 AWS 上部署在 Python 3.6 上运行的 Django 项目

问题描述

我之前也使用此资源使用 Python2.7 完成了此操作

但是，这个错误对我来说是新的

Error installing dependencies: Command '/opt/python/run/venv/bin/pip install -r /opt/python/ondeck/app/requirements.txt' returned non-zero exit status 1

以下是详细的回溯

我不明白这个问题似乎是什么。

会喜欢任何可能的方向。

解决方案

您已经安装了 Python 2 包，但您使用的是 Python 3。

concurrent.futures 库包含在 Python 3 的标准库中。您应该从您的 requirements.txt 中删除它。
