检测求解器路径以及是否可用
from inspect import getmembers
import pulp
for m in getmembers(pulp.solvers):
try:
if isinstance(m[1], type):
print('--', m[1]().available(), m)
except Exception:
continue
代码结果如下所示
其中cbc求解器的路径为/Users/MZYzhouyi/opt/anaconda3/envs/pure_pytorch/lib/python3.9/site-packages/pulp/solverdir/cbc/osx/64/cbc，而改文件是root文件，pyinstaller权限不足不会打包该文件

使用pyinstaller打包
sudo pyinstaller --noconfirm --onefile --console --add-data "/Users/MZYzhouyi/opt/anaconda3/envs/pure_pytorch/lib/python3.9/site-packages/pulp:pulp/" employee.py
# 将对应的依赖放进去，而employee.exe运行的时候，pulp包能自动搜索是否存在cbc
