Following this post I created an environment for pypy2.7: conda create -c conda-forge -n pypy2.7 pypy2.7. In the new environment I can now do
$ python -c "import sys; print(sys.executable)"
/usr/bin/python
and
$ pypy -c "import sys; print(sys.executable)"
/home/julian/miniconda2/envs/pypy2.7/bin/pypy
So there is no python in the environment, therefore the system's python gets used, but there is pypy im the environment, which is exactly what we want. Obviously if I try to
$ pypy
Python 2.7.13 (0e7ea4fe15e82d5124e805e2e4a37cae1a402d4b, Dec 28 2017, 20:45:53)

Traceback (most recent call last):

ImportError: No module named numpy
it does not work.
According to the post mentioned earlier, I should now be able to conda install numpy, however this will do:
conda install numpy

Notice the python conda-forge/linux-64::python-3.9.2-hffdb5ce_0_cpython, so instead of installing numpy to pypy, it installs a new python3.9.
And sure enough after the numpy installation I get
$ python -c "import sys; print(sys.executable)"
/home/julian/miniconda2/envs/pypy2.7/bin/python
and numpy is still not installed for pypy.
How do I get conda install to work on pypy instead of python?
All of this is happening on the WSL (Ubuntu 18.04).
