bash:/python/run/venv/bin/activate：没有这样的文件或目录

Question

我正试图通过AWS elastic beanstalk部署我的django应用程序；在过去的两天里，我遇到了一个问题，我已经缩小了范围

部署过程中的某个命令失败，此命令如下所示：

container_commands:
  01_migrate:
    command: "python3 manage.py migrate"
    leader_only: true

AWS EB控制台日志中告诉我这一点的部分将我引向cfn-init.log，检查这一点告诉我同样的事情。然而，在cfn-init-cmd.log中，我看到了这一点

让我相信问题在于我的虚拟环境无法激活。一些在线研究告诉我激活venv的命令应该是

opt/python/run/venv/bin/activate

我试图通过eb-ssh激活它，但没有成功，我收到了消息

bash: opt/python/run/venv/bin/activate: No such file or directory

当我检查opt目录时，由于缺少python文件夹，这一点得到了证实。我不知道为什么虚拟环境不存在/无法被激活，如果您能提供帮助，我将不胜感激

Answer 1

事实证明，我的应用程序是为amazon linux 1和；二,；环境是AmazonLinux2

我不得不将我的环境降级为AL1 python 3.6，并将应用程序中的一些设置还原为AL1（例如wsgi路径）

它现在已启动并运行：）

Answer 2

试试这个：

container_commands:
  01_migrate:
    command: "/opt/python/run/venv/bin/python3 manage.py migrate"
    leader_only: true

不要在“激活它”中思考，只需从venv运行python即可
