How to install specific version of the cloud datastore emulator by gcloud ?

I am running clusterfuzz tool on macOS.
While when excute fuzzy bot by python butler.py run_bot --name fuzzy-mac ./fuzzy-mac, the error logs come:

| Traceback (most recent call last):

And after searching the errors, I found google.cloud.ndb should install the version of google.cloud.datastore under 2.0.0.
And what I install from gcloud components install can only install the version 2.3.1.

How should I install the specific version of datastore?
Thank you.

Now I tried to use gcloud components update 201.0.0 to downgrade the version of google.cloud.datastore, then I can't use gcloud because the version dosen't support Python 3.7.
This is not a way to try.
