无法找到包 python-pytest答案

【问题标题】：Unable to locate package python-pytest无法找到包 python-pytest
【发布时间】：2021-12-16 05:43:58
【问题描述】：

我最近不得不重置我的机器，所以必须重新安装所有东西。

我想使用PyTest 运行Python 文件。

Bash 终端：

me@PF2DCSXD:/mnt/c/Users/dabell/Documents/GitHub/workers-python/workers/composite_key/compositekey/tests$ pytest -s test_composite_key.py

Command 'pytest' not found, but can be installed with:

sudo apt install python-pytest

me@PF2DCSXD:/mnt/c/Users/dabell/Documents/GitHub/workers-python/workers/composite_key/compositekey/tests$ sudo apt install python-pytest
[sudo] password for danielbellhv:

E: Unable to locate package python-pytest

我能够安装pip，按照这篇文章的Solution。

如果还有什么我可以添加到帖子中的，请告诉我。
