Tornado Install Issue

I'm trying to install tornado (pip install tornado) and am getting the following error... Command /usr/bin/python -c 'import setuptools, tokenize;__file__='/tmp/pip_build_username/

Solution 1:

I had the same issue while installing another program. It was not a decoding problem but a permission problem. Try the following:

    pip install --user tornado

I hope that works for you as well.
