IBM Bluemix error"You are using pip version 8.1.1, however version 9.0.1 is available"

Question

I have tried to deploy my app on IBM Bluemix from the GitHub source.The app is started, but I got the following error:

But I have installed the latest version of pip:

hduser@ubuntu:~$ python --version
Python 2.7.13 :: Anaconda 4.3.1 (32-bit)
hduser@ubuntu:~$ pip --version 
pip 9.0.1 from /home/hduser/anaconda2/lib/python2.7/site-packages (python 2.7)

How to solve this?

Answer 1

The error or warning message is not on your machine, but in the buildpack environment on Bluemix. You cannot update that environment.

The only way to get around the pip-related message would be to use another buildpack. Something similar regarding pip and IBM Bluemix has been discussed here on Stackoverflow.
