Boosting-R-CNN RuntimeError: Error compiling objects for extension

My original environment was able to run normally, but later my computer had a problem and the environment became unusable. I need to reinstall the environment now, and the installation steps are the same as before. Win10 system installation pytorch 1.7.0, mmcv=1.4.0, mmdetection=2.17.0. But every time it installs mmcv, the following error occurs, and I don't quite understand where the problem lies. I hope you can help me, thank you!

Sorry, I have no idea what is going on. Maybe you can contact mmdet team to help you. Or you may try the new version of mmdet. Maybe it works.
