Docker Error: Service web Failed to Build

I am attempting to build a docker container from a makefile using the command ‘make dev’, and it keeps giving me this error:

PS C:UsersjohnsOneDrivedocumentsGitHubsidewalkwebpage> make dev

I have tried a lot of fixes on my own and from Google but nothing seems to work. Any thoughts on what to do would be helpful!
Here is a link to the GitHub repository which has the files being used to create the container:
