Hi

I would recommend using the provided install script instead of manually building the packages. Could you try following these instructions for installation and see if it works: https://github.com/manthan99/covins/tree/master#3-basic-setup

Make sure that you clone this repository instead of the one provided in the instructions.

I suggest doing a fresh installation in a new workspace with the provided instructions. Let me know if you still have any issues.

Thank you

Best Manthan

Actually I followed the instuction you mentioned,but the issue occured in the final step --building the covins_backend I builded the covins sucessfully before ,but I failed to build the covins_g .

Hi

Probably the issue was caused because I had renamed the repository without taking into account some of the paths in the install script. I have now switched back to the original name for now and thus it should not be an issue anymore. Thus I suggest reinstalling everything in a fresh workspace. Let me know if you still encounter any errors.
