ModuleNotFoundError:没有名为“pysftp”的模块

Question

当我试图在木星笔记本中使用'pysftp‘模块时，我收到了以下错误：

最终目标:通过一个用Python编写的基于web的应用程序，将文件从Unix服务器自动下载到Windows文件夹。

在此过程中，当我试图连接到WINSCP以允许python代码登录到Unix服务器(username@hostname)时，我使用了'pystftp‘模块，但是我得到了以下错误消息：

错误消息：ModuleNotFoundError: No module named 'pysftp'

采取的行动：

1. pip list -查看python中已经安装的包；我没有显示pysftp
2. pip install pysftp -安装pysftp模块；在jupyter记事本

中运行以下错误

错误信息：

要求:请指导并帮助我实现我的最终目标。

我在用朱庇特笔记本写代码

首先建议:您应该检查的位置，并从该目录下转到cmd ->并键入：pip安装pysftp。如果安装成功，那么问题就在脚本运行的解释器选择中。
