The reason might be that I tried to install Python from Microsoft Store, which didn't had pip and that I downloaded pip following this tutorial原因可能是我尝试从 Microsoft Store 安装 Python,它没有 pip 并且我按照本教程下载了 pip
I tried to install it from sys:我尝试从 sys 安装它:
import sys
!{sys.executable} -m pip install facebook_sdk]
But got the following one:但是得到了以下一个:

I tried to install it (and a random package) with conda install pip
but got almost the same error我尝试使用conda install pip
安装它(和一个随机包)但得到了几乎相同的错误

Successfully installed pip-19.2.3
But still had the error after shutting down the kernel, closing the jupyter window terminal.但是关闭kernel,关闭jupyter window终端后仍然有错误。
So you are using conda and Pip... why dont you try installing pip from Conda??所以你正在使用 conda 和 Pip ......你为什么不尝试从 Conda 安装 pip ?
Sorry for not comment instead but I have not enough reputation.很抱歉没有发表评论,但我没有足够的声誉。
conda install pip
