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

Question

我在使用Python2.7和使用此资源之前也已经做到了

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

我不明白这个问题是什么。

会喜欢任何可能的方向。

Answer 1

您已经安装了Python 2软件包，但正在使用Python 3。

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

Answer 2

这个问题是一个门面。

这个问题是不是在requirements.txt作为回溯但在SSL密钥提及。 我的SSL密钥已损坏，因此正在向我显示此错误。

我认为这些错误是由于以下方面的差异引起的：

• 配置文件，例如key.pem，.ebextension / *文件
• 项目包，例如postgresql93-devel，git等

希望这对您有所帮助。
