#背景:最近在学习Yolo模型,然后其中要下载jupyter(有点像一个超级笔记本,可以进行交互式编程,适合深度学习,数据分析等应用)。
#问题:
在执行完pip install jupyterlab后报错:
Preparing metadata (pyproject.toml) ... error
error: subprocess-exited-with-error
× Preparing metadata (pyproject.toml) did not run successfully.

note: This error originates from a subprocess, and is likely not a problem with pip.

#解决方案:
去网上检索,然后分析出这段报错的可能原因:
pywinpty
是一个 Python 包,它提供了对 WindowsPTY 的支持,这通常用于 JupyterLab 等工具以实现终端功能。为了编译这个包,需要 Rust 编程语言的编译环境。
于是我就去rust官网去下载了并按步骤配置了编译环境。
然而这个时候我在执行完 pip install jupyterlab还是发现不可行,我后面想了下我是在conda环境下操作的,其实当时下载conda的时候就已经自动安装配置好了rust编程语言的编译环境,所以应该是pywinpty包丢失的问题。
conda install -c conda-forge pywinpty
输入如上代码即可安装好 pywinpty包,然后再执行pip install jupyterlab就可以正常下载了。
