IndexError: List index out of range

Hi, I was trying to install opticspy. I have Anaconda system on windows with Spyder 3. 1.4 and Python 3.6 installed. I got the following error: Please suggest a remedy

!pip install opticspy Collecting opticspy Downloading opticspy-0.2.1.tar.gz (1.3MB) Requirement already satisfied: numpy>=1.9.3 in c:\programdata\anaconda3\lib\site-packages (from opticspy) Requirement already satisfied: matplotlib>=1.4.3 in c:\programdata\anaconda3\lib\site-packages (from opticspy) Collecting unwrap (from opticspy) Downloading unwrap-0.1.1.tar.gz Complete output from command python setup.py egg_info: Traceback (most recent call last): File "C:\ProgramData\Anaconda3\lib\site-packages\setuptools-27.2.0-py3.6.egg\setuptools\msvc.py", line 474, in init IndexError: list index out of range

During handling of the above exception, another exception occurred:
