[marcoscale98]

Describe the issue
I follow the quickstart using Python 3.7 as described in the guide

But I got the following error:
pip3 install -r .\checkout\requirements.txt ERROR: Ignored the following versions that require a different python version: 0.5.0a0 Requires-Python >=3.8; 1.11.0 Requires-Python >=3.8; 1.12.0 Requires-Python >=3.8; 1.12.1 Requires-Python >=3.8; 1.13.0 Requires-Python >=3.8; 1.13.0rc1 Requires-Python >=3.8 ERROR: Could not find a version that satisfies the requirement dapr<1.14.0,>=1.13.0a (from versions: 0.6.0a0, 0.6.0a1, 0.7.0a0, 0.8.0a0, 1.0.0rc2, 1.0.0rc3, 1.0.0rc4, 1.0.0, 1.1.0rc1, 1.1.0, 1.2.0rc1, 1.2.0, 1.3.0rc1, 1.3.0, 1.4.0rc1, 1.4.0, 1.4.1, 1.5.0rc1, 1.5.0, 1.6.0rc1, 1.6.0, 1.6.1, 1.7.0, 1.8.0rc1, 1.8.0rc2, 1.8.0, 1.8.1, 1.8.2rc1, 1.8.2, 1.8.3rc1, 1.8.3, 1.9.0rc2, 1.9.0rc4, 1.9.0, 1.9.1, 1.10.0rc1, 1.10.0) ERROR: No matching distribution found for dapr<1.14.0,>=1.13.0a
