setuptools_scm: errors with conda build

Hello, I created a recipe for a project and I’m using setuptools_scm. For this project my source section of my recipe is like:

source:
  git_tag: my-branch
  git_url: PATH-to-git.git

my script section is:

  script:
    - python -m pip install --no-deps --ignore-installed src/pythonKarabo

where is located my setup.py

When I try to build that using conda build I’m facing this error:

    Complete output from command python setup.py egg_info:
    Traceback (most recent call last):

    Make sure you're either building from a fully intact git repository or PyPI tarballs. Most other sources (such as GitHub's tarballs, a git checkout without the .git folder) don't contain the necessary metadata and will not work.
    
    For example, if you're using pip, instead of https://github.com/user/proj/archive/master.zip use git+https://github.com/user/proj.git#egg=proj
