i follow the instructions of the https://pdos.csail.mit.edu/6.S081/2021/labs/util.html

@yurneroma hi, I did the whole experiments using WSL2 on windows. and I never came across this error before.

I just rebuild the project successfully on a new enviroment (on windows WSL2) following the official instructions. So I am guessing this is related to the platforms and the corresponding library?
