~/.docker/cli-plugins could not exist while installing docker-clip

[xinity]

while following blindly the documentation into a docker VM , i've had this error message:
curl -sf https://raw.githubusercontent.com/lukaszlach/clip/master/docker-clip -o ~/.docker/cli-plugins/docker-clip
chmod +x ~/.docker/cli-plugins/docker-clip
chmod: cannot access '/home/xinity/.docker/cli-plugins/docker-clip': No such file or directory
perhaps we should make sure before installing docker-clip, minimum requirements are set :)

happy to help anytime,

This is the same issue as #6, the reason is the same.
