Maybe, there can be a PATH problem.也许，可能存在 PATH 问题。 You can add the Python to Windows Path like this https://geek-university.com/add-python-to-the-windows-path/ and you can check again Python versions with commands on cmd: python -v or python3 -v您可以像这样将 Python 添加到 Windows 路径https://geek-university.com/add-python-to-the-windows-path/并且您可以使用 cmd 上的命令再次检查 Python 版本： python -v或python3 -v
