How to use sphinx extensions?

[kkoogqw]

I tried to test the example in section Custom Sphinx extensions in the guide book. While using the extension sphinx-inline-tabs, I followed the documents with pip install sphinx-inline-tabs and add the extension in the file _config.yml:

sphinx:
  extra_extensions          :
    - sphinx-inline-tabs   

but when building the book, it threw an error:

Extension error:
Could not import extension sphinx-inline-tabs (exception: No module named 'sphinx-inline-tabs')
Traceback (most recent call last):
  File "/home/gqw-wsl/anaconda3/lib/python3.8/site-packages/sphinx/registry.py", line 409, in load_extension
    mod = import_module(extname)
  File "/home/gqw-wsl/anaconda3/lib/python3.8/importlib/__init__.py", line 127, in import_module
    return _bootstrap._gcd_import(name[level:], package, level)
  File "<frozen importlib._bootstrap>", line 1014, in _gcd_import
  File "<frozen importlib._bootstrap>", line 991, in _find_and_load
  File "<frozen importlib._bootstrap>", line 973, in _find_and_load_unlocked
ModuleNotFoundError: No module named 'sphinx-inline-tabs'

but use the command pip list I can see the package:

sphinx-inline-tabs                 2021.3.19b5

I am not sure if I missed some necessary steps, and no similar problems were found in the issues.
So I wander how I can use sphinx extensions correctly. Thanks!

Heya, yes you still have to install the package into your python environment

    - sphinx_inline_tabs
