您好，请问这个问题解决了嘛？Have you solved the problem？Thanks!!!
Hello, have you solved it? I met with similar problems :(
@vickyliuliu you can try this in conda environment: conda install -c conda-forge lap
Also would like to know if this is resolved. I'm am getting the same issue on RHEL 7.8.
@mphillips-valleyit Can you run g++ --version and paste it here?
@gatagat Thanks for responding. Actually I didn't have g++ installed! (Just gcc.) After installing that, pip install lap works although pip install lapsolver does not--but that's a separate issue I guess.
@mphillips-valleyit Glad it worked and thanks for reporting back. And yes, this repo has nothing to do with lapsolver.
@vickyliuliu you can try this in conda environment: conda install -c conda-forge lap
very helpfull thanks alot!
@gatagat following your procedures had it solved
-sudo apt install g++
-pip install lap
