尝试使用pip安装安装Jupyter笔记本时出现此错误

我正在使用Python3.9和PIP20.2.3。我已经安装了微软Visual C++ +2015-2019可重分发-1427.12112/P>

需要帮助来解决这个问题

Answer 1

试试这个：

python -m pip install jupyter notebook

Answer 2

我通过ms的安装程序安装了重新安装的visual c 2019构建工具，然后使用

    python -m pip install  upgrade pip

在那之后它就开始工作了。我使用的是通过Chocolate安装的python 3.7

Answer 3

根据我的经验，我认为Jupyter还不支持Python3.9，所以我所做的是安装较旧的版本，即Python3.8
