issue doing smart contract tutorial

[hectorniyan 0]

I have followed the crowd funding tutorial on your website.

I am using a macbook pro with latest apple os installed. Python 3 and Pip3 are installed.

When I run the command

`erdpy contract build`  I get the following error:

projects/elrond/venv/lib/python3.7/site-packages/pkg_resources/__init__.py", line 786, in resolve
    raise DistributionNotFound(req, requirers)
pkg_resources.DistributionNotFound: The 'erdpy==0.5.1' distribution was not found and is required by the application

Can you help me please?

Thanks
