python - bin/python3 : cannot execute binary file: Exec format error

Question

我刚刚创建了一个新的 django 项目，并将其推送到 git，现在我尝试使用 Digital ocean 来部署它。

我安装了所有必需的东西，例如 pip、python 等，但我无法使 python manage.py runserver 工作。

((g-v)是我的虚拟环境，所以这不是问题。)

它抛出此错误:

(g-v) root@ubuntu-s-4vcpu-8gb-blr1-01:/home/g-v/src# python manage.py runserver
  File "manage.py", line 14
    ) from exc
         ^
SyntaxError: invalid syntax

我读了一些建议尝试 python3 manage.py runserver 的帖子，但当我尝试时，我收到此错误:

(g-v) root@ubuntu-s-4vcpu-8gb-blr1-01:/home/g-v/src# python3 manage.py runserver
-bash: /home/g-v/bin/python3: cannot execute binary file: Exec format error

我的pip list命令输出:

(g-v) root@ubuntu-s-4vcpu-8gb-blr1-01:/home/g-v/src# pip list

Answer 1

当我忘记打开 venv 时，我观察到了这样的错误。

尝试 source ./path-to-venv/bin/activate 并重试 manage.py runserver 命令。
