I am installing Open-edx devstack for juniper.master but getting the following error after running the command make dev.provision.

Hello @Piyush_Nikam,

Follow the below steps to resolve the error:

  1. Open LMS shell: make lms-shell
  2. Move or delete this file: rm /root/.pip/pip.conf
  3. Install setuptools_scm: pip install setuptools_scm

Follow the same in make studio-shell and then you can do make

This approach helped me to figure out the same in my installation today, hope this will work for you though I was not able to find the root cause behind this (due to lack of time).
