Deploy command fails even with extras installed

1.5

Describe the problem

When running dlt deploy the command fails with the message below even though dlt[cli] is installed.

WARNING: Please install additional command line dependencies to use deploy command:
pip install "dlt[cli]"
We ask you to install those dependencies separately to keep our core library small and make it work everywhere.
NOTE: Please refer to our docs at 'https://dlthub.com/docs/walkthroughs/deploy-a-pipeline' for further assistance.

This is because dlt[cli] extras do not include all the dependencies needed by the deploy command. Namely the pip dependency.

Expected behavior

No response

Steps to reproduce

1. Install dlt[cli] into a virtual environment without pip. For example using a package manager such as uv.

uv venv
source .venv/bin/activate
uv pip install "dlt[cli]"

2. Run the deploy command.

Additional information

1. Do not hide the exception and replace it with a custom message. This makes it difficult to debug. Instead, include the exception message with the warning.
2. Include the pip dependency in the cli extras.
