Invalid version in setup.py

[fuu38]

My enviroment:

• Python:3.10.10
• pip:23.0.1
• Kernel:6.2.12-arch1-1

problem

When I tried to install conformer locally, I encountered error shown below.
I'm not so familiar with Python and pip, but maybeversion='latest'in setup.py is cause of this problem.
Finaly,with replacing this parameter with number(I replaced with 1.0) is worked for me

>pip install -e conformer  
Defaulting to user installation because normal site-packages is not writeable
