starting container process caused "exec: \"uwsgi\": executable file not found in $PATH": unknown

Question

I am trying to start a docker container and I am getting the error "Error response from daemon: OCI runtime create failed: container_linux.go:349: starting container process caused "exec: "uwsgi": executable file not found in $PATH": unknown". I think it is related to my dockerfile and uwsgi file but I am unsure as to why I cannot start my container. I have already pip installed uwsgi. I also haven't found any other solutions apart from installing uwsgi even though its already there
