前言

        最近做的项目需要安装lap库,但是当我天真的输入pip install lap准备满心欢喜的等待安装成功却发现...,它报错了,这是一个从未见过的、非常长的报错,它长这个样子:

pip3 install lap

        天呐!这是什么错误?完全看不懂好吧...

        后来又在网上反反复复找到了这样一条命令:

pip install git+git://github.com/gatagat/lap.git

        作者打着包票跟我讲:这次一定行! 

        然后....(哎呦,真香,哎呦诶。)

lap库就该这么安装_第1张图片

 正确安装命令

注视:这是一条非常珍贵的命令!

conda install -c conda-forge lap

如果不是anaconda环境的小火炮可以试试将conda换成pip喔! 

完毕!

如果大家觉得有帮助的话!麻烦点赞+收藏喔,谢谢大家!
