Problem installing Owlready2

[munaibalhelali]

Hi everyone,
I am having a problem installing Owlready2. I have tried to use "pip3 install owlready2" as well as downloading the source code and using "python3 setup.py build" but either way I ended up with the same error as shown in the following output:

$ python3 setup.py build

How can I solve this problem?

Thanks in advance for the help
