  --- BEGIN ISSUE ---
  bootstrap script cannot be executed without setuptools already installed
  The `bootstrap.py` script cannot be used to bootstrap from an environment without setuptools.  The script imports `pip` which requires setuptools to be be installed.  This behavior was introduced in #933.

  2 If setuptools is not already installed in the environment, it's not possible
