现在当我运行命令 locust --help

我在命令行上得到这个

'locust' is not recognized as an internal or external command,
operable program or batch file

可能是什么问题？任何帮助将不胜感激。

你好像没有在环境变量PATH中添加python 3.7。虽然这可以在安装 python 本身时通过选中将 Python 添加到路径的框来实现。但是，您仍然可以通过转到这台PC--右键单击->属性-->高级系统设置-->环境变量选项卡-->系统变量-来添加Python37的位置（安装python37的位置） -编辑路径并添加价值*。

我最近编写了在 windows 上设置 locust 的步骤，这可能会有所帮助 -https://www.qamilestone.com/post/set-up-locust-on-windows -问候， 阿努拉达
