狮身人面像找不到熊猫

如何解决狮身人面像找不到熊猫

我正在尝试使用 sphinx 记录 Python 类。我使用 Python 3.9.2 和 sphinx-build 3.5.2。我正在运行命令 sphinx-build -b html source build 将 .rst 文件转换为 .html 文件。我已经在代码套件中的其他类和函数上成功地执行了这个配置，所以我知道他们组织文件的方式没有问题。当我运行命令时，出现以下错误；

Warning: autodoc: Failed to import class 'ReadTextFileKeywords' from module 'read_files'; the following exception was raised: No module named pandas

我确实在我的虚拟环境中全局加载了最新版本的 Pandas。有谁知道为什么它无法加载熊猫以及我如何解决这个问题？

作为参考，文件结构如下所示；

并且索引文件具有以下格式

.. Core Utilities documentation master file,created by
   sphinx-quickstart 
   You can adapt this file completely to your liking,but it should at least
   contain the root `toctree` directive.

Welcome to Core Utilities's documentation!

Indices and tables
==================

* :ref:`genindex`
* :ref:`modindex`
* :ref:`search`

当我从 operating_system 模块导入文档字符串时，Sphinx 工作得很好，所以我知道这不是问题。当我尝试从 read_files 模块导入时失败。 read_files.rst 文件具有以下格式。

**********
read_files
**********

The ``read_files`` module contains methods and classes that allow a user to read different
types of files in different ways.  Within the module a user will find functionality that 
allows them to read text files and csv files by columns and keywords.  This module
also contains functions to read sqlite databases,xml files,json files,yaml files,and html files

.. autoclass:: read_files.ReadTextFileKeywords
   :members:
