I got this error when running pip install pillow command in lubuntu. I am having python 2.7

I already tried this command pip install -U setuptools which was suggested in some other post, but to no effect.]

Answer 1

First off, running the commands as a user with root priviledges is not the same thing as using sudo pip install "whateveryouaretryingtoinstall", just making sure that is clear. As said earlier, it looks like some kind of compilation error, so try installing pip again and then run it. If that doesn't work try installing the package manually and if that doesn't work, than it must be a problem with the package.
