Unable to install Brotli part of dash module - Python

[Brendan Smith]

Hi

I am unable to install Dash on python as the installation process stops at the error received at Brotli installation stage.

Versions:

1. Windows 10

2. Python 3.11

The following steps were completed:

1. pip install dash --> Failed and proceeded to update pip, wheel and setuptools

2. Again performed pip install dash and the execution ends with errors. Below is the complete log
