python - PyCharm IDE 中的 pytest 安装

Question

我是编程新手。我在以下链接中为 python 开发配置 PyCharm 社区版：https ://realpython.com/pycharm-guide/

我想在设置/工具中配置后尝试 pytest 选项并选择“默认测试运行器：Pytest”。尝试在 IDE 中运行测试时，我有：

Traceback (most recent call last):
  File "C:\Program Files\JetBrains\PyCharm Community Edition 2019.3.3\plugins\python-ce\helpers\pycharm\_jb_pytest_runner.py", line 4, in <module>
    import pytest
ModuleNotFoundError: No module named 'pytest'

尝试了 python 集成工具的修复选项并出现此错误：

尝试修复 pytest 包时出现 Pycharm 错误

我从 cmd 中检查了 PIP 包：使用官方 python 指南中推荐的以下命令：

1）pip --version检查已安装的版本，并返回版本号pip 19.2.32 c:\users\user_name\appdata\local\programs\python\python38-32\lib\site-packages\pip (python 3.8) ）python -m pip install -U pip setuptools wheel 检查成功，但轮子失败并出现错误，如下所示：

我尝试修复修复/卸载并安装仍然出现这些错误我尝试从标准库引导它：

python -m ensurepip --default-pip

更新 1

令人惊讶的是，当我检查它时，我没有找到添加到 Windows 环境变量的 python 路径，但我确定我在安装 python 3.8 包“将 python 3.8 添加到 PATH”时检查了该选项我通过“编辑”手动将路径添加到 Windows系统环境变量”但还是有这个问题
