This solution worked for me.

You will need to create a pyinstaller hook for packages that depend on setuptools' get_distribution() to obtain metadata information about the package.

Create a hook file in some hooks directory. The file name should be hook-<modulename>.py for pyinstaller to find it properly (i.e. hook-gcloud.py).

Solution : Create two hook files:

• hook-gcloud.py

• hook-grpc.py

In hook-gcloud.py write below code and save it :

from PyInstaller.utils.hooks import copy_metadata
datas = copy_metadata('gcloud')

In hook-grpc.py write below code and save it :

from PyInstaller.utils.hooks import collect_data_files
datas = collect_data_files ( 'grpc' )

Now copy and paste the both files to /lib/python3.8/site-packages/PyInstaller/hooks/ directory.
