I am using releasesync-engine-17.1.16. On executing, I get below error.

You are using pip version 8.1.2, however version 9.0.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

Also, my environment settings:

 % python --version  
Python 2.7.12
 % pip --version
pip 8.1.2 from /usr/local/lib/python2.7/dist-packages (python 2.7)

How to solve this error?

[foxtrot9]

Update setup.sh to (On line number 181 and 179).

pip install 'pip==9.0.1' 'setuptools==34.3.1'

Also, add below line after 174 in setup.sh

pip install 'pyparsing==2.2.0'

And also add pyasn1==0.2.3 at end of requirements.txt
