dbt debug fails to find the adaptor

[abhyissstoxx]

Hello,

I have Python 3.12.3 built from source.
Also, I built dbt-bigquery from source using 'make dev'
All installed successfully, including dev-requirements dependencies as:-

$ pip list | grep dbt
dbt-adapters              1.1.0rc1
dbt-bigquery              1.8.0b2           /home/localuser/development/dbt-bigquery
dbt-common                1.0.2
dbt-core                  1.8.0b3
dbt-extractor             0.5.1
dbt-semantic-interfaces   0.5.1
dbt-tests-adapter         1.8.0b1

dbt-core is installed from git as it is dependency in dev_requirements,

$ dbt --version
Core:
  - installed: 1.8.0-b3
  - latest:    1.7.13   - Ahead of latest version!

Plugins:
 

It shows not dbt-bigquery plugins ? ---WHY

Now when I go to the project directory, of dbt, and run dbt debug,

I get error

15:50:40  Running with dbt=1.8.0-b3
15:50:40  Error importing adapter: No module named 'dbt.adapters.bigquery'
15:50:40  Encountered an error:
Runtime Error
  Credentials in profile "projection", target "dev" invalid: Runtime Error
    Could not find adapter type bigquery!

Any idea why ?

Need help

Thanks,
