Python jupyter安装但'；朱庇特'；当我尝试运行时，无法识别

我安装了Jupyter笔记本，它报告满足了要求，但当我尝试运行时，它报告“Jupyter”未被识别为内部或外部命令

我猜我缺少路径定义，但找不到jupyter.exe

我看到stackoverflow上的其他帖子说要按照安装说明设置python库路径，但我搜索了jupyter安装，没有找到对此的引用

有什么建议吗

顺便说一句，完全是Python新手

这里我展示了python已经安装并可以运行

检查python安装文件夹内的脚本文件夹中是否有名为jupyter的exe。如果是，则将脚本文件夹添加到路径中。

我建议您使用python的anaconda发行版。它会处理一切。

脚本文件夹中没有名为jupyter的文件。什么是水蟒？是否需要删除已安装的python？是的，卸载python。您将转到anaconda，选择一个版本并安装它。有关anaconda的问题，请参阅
