Windows环境下Jenkins流水线使用pipenv报错求助

各位好，我在Jenkins构建过程中调用pipenv的时候遇到了报错，具体信息如下：

10:27:55  pipenv : The term 'pipenv' is not recognized as the name of a cmdlet, function, script file, or operable program.
10:27:55  Check the spelling of the name, or if a path was included, verify that the path is correct and try again.

我已经手动确认过环境变量路径是正确的，而且也在Jenkins的构建配置里专门设置了路径，但还是出现这个问题。有没有朋友遇到过类似的情况？或者我是不是还有什么细节没考虑到呀？
