how to run dbt using visual code

Hi Everyone,
plan to use visual code to develop dbt package. but having hard time install dbt. i did install the python and add python path to the environment. but when in the visual code terminal, tried to install dbt, it keep saying
ERROR: Could not find a version that satisfies the requirement dbt==0.19.0 (from versions: none)
ERROR: No matching distribution found for dbt==0.19.0

anyone can help me on this? thanks so much.
