尝试从 Git-Bash 运行 Jupyter Notebook 但得到“zmq.h”没有文件或目录错误

Question

我已经安装了 Anaconda 并安装了 Git Bash 通过 ZD574D4BB40C84961791A.C69Z 运行命令安装 Anaconda 并将目录添加到 PATH 变量后，我无法运行 Git Bash 的 Jupyter 笔记本。 它提供了以下错误。

 jupyter notebook
_cffi_ext.c

收到错误后，我检查了 Jupyter 上的版本，看看是否有问题。 以下是我收到的

$ jupyter --version

我尝试安装以下软件包，但它指出所有请求的软件包都已安装（使用 conda install 而不是 pip）

我发布了我的 PATH 变量列表的图片。

似乎某些东西一定破坏了jupyter环境。
对我来说，它在重新安装后工作：

pip install jupyter
