Python安装 jupyter notebook报 pywinpty缺少Rust 和 Cargo

问题描述

Python  执行安装 pip install jupyter 命令报这个错误

ERROR: Command errored out with exit status 1:

     command: 'e:\XXX\python\python.exe' 'e:\XXX\python\lib\site-packages\pip\_vendor\pep517\_in_process.py' prepare_metadata_for_build_wheel 'C:\Users\xxx\AppData\Local\Temp\tmpg764gw5c'

原因分析： 

因为缺少 Rust 和 Cargo 导致的，我先后用了升级 pip 和 setuptools都没有解决

python -m pip install --upgrade pip

python -m pip install --upgrade pip

 重新用命令安装这个包也不成功，都可以试试

pip install --upgrade pywinpty

解决方案：

访问 rustup.rs - The Rust toolchain installer ，按照网站上的指示下载并安装 Rust。安装过程中，确保选择将 Rust 添加到系统路径中，以便在命令行中可以访问 rustc 和 cargo

重启电脑后再次执行就可安装成功了

pip install jupyter
