Installation Failure: Invalid Version Specifier in setup.py for extract-msg<=0.29.*

[shrijayan]

Describe the bug

When trying to install textract==1.6.4, the installation fails due to an issue with the install_requires field in the setup.py file. Specifically, the extract-msg<=0.29.* entry is not a valid version specifier because the .* suffix can only be used with the == or != operators.

To Reproduce

Steps to reproduce the behavior:

1. Run pip install textract==1.6.4 in a Python environment.
2. Observe the error during the installation process when building the wheel.

Expected behavior

The package should install successfully without errors.

Error Output

error in textract setup command: 'install_requires' must be a string or list of strings containing valid project/version requirement

specifiers; .* suffix can only be used with `==` or `!=` operators
extract-msg<=0.29.*
             ~~~~~~~^

Desktop (please complete the following information):

• OS: MacOS
• Textract version: 1.6.4
• Python version: 3.11
• Virtual environment: yes

Additional context

It seems like the issue is related to invalid version specifiers in the setup.py file of the textract package. A potential fix would be to update the version specifier to extract-msg<=0.29 or resolve the versioning conflict.
