我正在创建名为countries_utils的第一个软件包，该软件包可在https://pypi.org/project/countries-utils上使用。

我已阅读以下教程：

1. 打包Python项目 https://packaging.python.org/tutorials/packaging-projects/
2. 管理应用程序依赖项https://packaging.python.org/tutorials/managing-dependencies/#managing-dependencies
3. 打包和分发项目https://packaging.python.org/guides/distributing-packages-using-setuptools/#distributing-packages

库countries_utils

该库的源代码可在bitbucket上获得：

• https://bitbucket.org/altf1be/countries-utils/src/master/

问题

1. 我运行命令pip install countries-utils
2. 我下载了该库的最新版本
3. 我运行python命令
4. 我使用import countries_utils
导入库
5. 我收到错误消息：ModuleNotFoundError: No module named 'countries_utils'

问题：我想念什么？

pip list命令的结果

pip list

错误

这是在python控制台中执行import countries_utils的结果：
