I'm trying to install pyobfuscate found here: <https://github.com/astrand/pyobfuscate> on my macOS Sierra using the following command `python setup.py install`but I get the following error:

```
running install
running build
running install_data
copying pyobfuscate -> /usr/bin
error: [Errno 1] Operation not permitted: '/usr/bin/pyobfuscate'

```

I've tried using `sudo` as well but I get the exact same error.
