Hi, thanks for reporting this. I can reproduce this, but only if I don't have an executable pip on PATH. Can you confirm that you have an executable pip binary where you're executing this?

[thusoy]

And if you indeed do have pip on PATH, it would be very helpful if you could run

$ wget https://registry.npmjs.org/grunt-pylint/-/grunt-pylint-1.3.1.tgz
$ tar xf grunt-pylint-1.3.1.tgz
$ cd package/tasks/lib
$ pip install --no-index --no-deps --ignore-installed ./pylint-1.5.4.tar.gz ./astroid-1.4.4.tar.gz ./colorama-0.3.6.tar.gz ./six-1.10.0.tar.gz ./lazy-object-proxy-1.2.1.tar.gz ./wrapt-1.10.6.tar.gz --target .

manually, and see if that works, as that's basically what npm is doing. Paste any output here if doesn't work and I'll see what I can about it!
