推荐答案

这意味着您的pip命令路径未在系统的路径变量中设置

this means your pip command path is not set in the path variables of system

您可以尝试执行以下操作:

You can try doing the following:

• 转到此Pc>属性>高级设置>环境变量

• go to This Pc>properties>Advanced Settings>environment variables

..然后单击新建

..然后选择您的python pip命令可用的路径

..then select the path where your python pip command is available

..并简单地给它命名为python38多数民众赞成

.. and simply give it a name python38 thats it

然后它将创建您的venv

then it will create your venv
