在 Django 项目中：

python manage.py shell_plus --ipython

正在按预期加载模型导入，例如，工作得很好。

当试图

python manage.py shell_plus --notebook

Jupyter 将启动。但是当尝试创建一个新的 django shell plus 笔记本时，我会得到以下导入错误：

我可能遗漏了一些东西，我很乐意提供更多详细信息并帮助重现该问题。

版本：

  • django 扩展 3.1.1
  • Django 3.1.6
  • jupyter 1.0.0
  • jupyter 客户端 6.1.12
  • jupyter 控制台 6.4.0
  • jupyter 核心 4.7.1
  • jupyterlab-pygments 0.1.2
  • jupyterlab-widgets 1.0.0

编辑：

我可以概括一下这个问题。执行时： python manage.py shell_plus --notebook 和打印sys.path我们得到

sys.path=
['/home/pumpkin/django_projects/book_management',
 '/home/pumpkin/miniconda3/envs/booking_j2/lib/python39.zip',
 '/home/pumpkin/miniconda3/envs/booking_j2/lib/python3.9',
 '/home/pumpkin/miniconda3/envs/booking_j2/lib/python3.9/lib-dynload',
 '/home/pumpkin/miniconda3/envs/booking_j2/lib/python3.9/site-packages']

这是预期的（它是当前激活的 conda env）

但是当尝试启动一个新的 Django shell-plus notebook 时，我们可以看到跟踪依赖于另一个 conda env：

[I 14:21:31.694 NotebookApp] Creating new notebook in 
[I 14:21:32.373 NotebookApp] Kernel started: 8d4013f7-ae9e-4bf4-80a3-ca9483e72f0b, name: django_extensions
[IPKernelApp] WARNING | Error in loading extension: django_extensions.management.notebook_extension

Traceback (most recent call last):
  File "/home/pumpkin/miniconda3/envs/django22/lib/python3.7/site-packages/IPython/core/shellapp.py", line 261, in init_extensions
    self.shell.extension_manager.load_extension(ext)

在此 conda env 中，未安装所需的模块。因此错误。

现在我的问题是，为什么 ipython(?) 不能在正确的 conda env 中运行？

请注意，运行时python manage.py shell_plus --ipython按sys.path预期运行。此外，在启动经典的 python 3 笔记本时，导入也会按预期进行。
