pip 20 broken for python 2.7 #694

Solution to issue cannot be found in the documentation.

Issue

I need to use python 2.7 for some old scripts. The pip (20.*) installed with it is broken. I got an ImportError: No module named pip._internal.cli.main when trying to use it (details at the end of this section).

When searching for pip package in $CONDA_PREFIX, I found that the package is not installed in $CONDA_PREFIX/lib/python2.7, but at the root of the env (the 2 first lines of the following find command)

$ find $CONDA_PREFIX/ -name "*pip*"
/home/<user>/miniconda3/envs/py27/site-packages/pip
/home/<user>/miniconda3/envs/py27/site-packages/pip-20.1.1-py3.6.egg-info
/home/<user>/miniconda3/envs/py27/bin/pip
/home/<user>/miniconda3/envs/py27/conda-meta/pip-20.1.1-pyh9f0ad1d_0.json
/home/<user>/miniconda3/envs/py27/lib/python2.7/pipes.pyc

/home/<user>/miniconda3/envs/py27/lib/python2.7/ensurepip/_bundled/pip-9.0.3-py2.py3-none-any.whl

Installing a pip <20 solve the issue, but a broken version of pip mustn't be installed by default.

The ImportError details:

$ conda create -n py27 python=2.7
