Django 服务器无法在 Docker 容器中启动

Question

我一直在尝试运行来自 https://github.com/hyshka/wagtail-vue-talk

的现有 Wagtail/Vue 实施

我已经安装了 Docker 并设置了容器，但是当我尝试从容器运行 Django 服务器时，它吐出以下代码：

root@e7d407eba535:/app# django-admin.py runserver 0.0.0.0:8000

During handling of the above exception, another exception occurred:

ImportError: No module named 'wagtail_vue'

到目前为止，我已经检查了设置和要求文件，重新安装了容器很多次。此错误通常与 PATH 配置或 __init__.py 文件有关，但所有这些似乎都已到位。 docker 容器中安装的包似乎也是正确的。

Frontend 的另一个容器工作正常，我的朋友在 MacOS 上执行相同的操作后一切正常（我在 Windows 10）。

目前我能想到的唯一选择是将所有内容移动到 Linux 虚拟环境，但我想避免这种情况。

Answer 1

关闭这个问题，因为我自己找到了 "solution"。在多次重新安装和重新配置所有内容后，我放弃并安装 Ubuntu 以及 Win10（双启动），它按预期工作。
