SyntaxError on unicode_literal occurs when I start a new terminal

Hi there,

I had a problem when I start a new terminal or when I use conda.

The problem seems to be related to unicode_literal.

Before this error occurs, I had a problem on path definition to libarchive.
Manually, I change the default path to libarchive_path = f'{sys.prefix}/lib/libarchive.13.dylib'
The error was removed at that time.

However, another error appears since I updated conda this morning.

The update included libarchive. I thought it would be related to the previous bug but it causes another error.

Does anyone know a good solution for this error?

I fixed the problem. 

I changed two points in /opt/intel/intelpython3/lib/python3.6/site-packages/libarchive/ffi.py.

1. unicode_literal -> unicode_literals

2. # libarchive_path = os.environ.get('LIBARCHIVE') or find_library('archive')
    libarchive_path = f'{sys.prefix}/lib/libarchive.13.dylib'

I hope that next update solves all problem.
