🔱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：

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。）
🔱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！
