The DatastoreGrpcStub requires a local gRPC installation, which is not found

When running app engine in Google using `dev_appserver.py app.yaml` and I got error

/usr/lib/google-cloud-sdk/platform/google_appengine/google/protobuf/internal/api_implementation.py:100: UserWarning: Selected implementation upb is not available. Falling back to the python implementation.

We are gradually rolling out the emulator as the default datastore implementation of dev_appserver.
If broken, you can temporarily disable it by --support_datastore_emulator=False

To solve this problem, simply passing argument to ignore datastore by

dev_appserver.py app.yaml --support_datastore_emulator=False

Solve environment is externally managed Pip install

error: externally-managed-environment × This environment is externally managed ╰─> To install Python packages system-wide, try apt install python3-xyz, where xyz is the package you are trying to install. If you wish to install a non-Debian-packaged Python package, create a virtual environment using python3 -m venv path/to/venv. Then use path/to/venv/bin/python and path/to/venv/bin/pip. Make sure you have python3-full installed. If you wish to install a non-Debian packaged Python application, it may be easiest to use pipx install xyz, which will manage a virtual environment for you. Make sure you have pipx installed. See /usr/share/doc/python3.11/README.venv for more information. note: If you believe this is a mistake, please contact your Python installation or OS distribution provider. You can override this, at the risk of breaking your Python installation or OS, by passing --break-system-packages. hint: See PEP 668 for the detailed specification.
