I'm not sure on this one, but the error message mentions it can't find "lib" (where it would install the package) and then can't find another package that the one you are installing relies upon. My starting point would be checking whether the lib / package directory is set correctly. Sorry I'm not sure what exactly it would be though.

It seems you are missing a system dependency (libpng), you haven't tell us on which operating system are you so I can't give you any specific advice but you can Google how to install it in your system

My operation system is ubuntu 18. i installed libpng dependency but still facing same issue.

Have you also installed libpng-dev? the file png.h seems to come from there.
