pytest 报错—— zsh: command not found: pytest

pytest 报错—— zsh: command not found: pytest

操作环境

• ubuntu 22.04.3
• vscode
• python和pip3版本

> python3 --version
Python 3.10.12

> pip3 --version
pip 22.0.2 from /usr/lib/python3/dist-packages/pip (python 3.10)

问题描述

在利用python3下载pip3后,利用pip3下载pytest,结果操作完仍然显示如下图：

 > pytest --version zsh: command not found: pytest 

产生原因

通过pip安装pytest不会使其成为系统命令，而是会将其安装到python

问题解决

使用命令：

> python3 -m pytest -v test_calculator.py

效果：
