pip install pywebview

doesn't work :

ERROR: THESE PACKAGES DO NOT MATCH THE HASHES FROM THE REQUIREMENTS FILE.
If you have updated the package versions, please update the hashes.
Otherwise, examine the package contents carefully; someone may have tampered with them.
    unknown package:
        Expected sha256 e352f587f82c173b28981fa0c893fab6124eb40d18c312e2bebf5346ab9f9f2c
             Got        01ba79f9811a992d246703311e749319e83a565709d025585eb0a635ca22e159

according to
https://www.wheelodex.org/projects/pywebview/
the above expected sha256 e352...9f2c
is the sha256 hash of pywebview-5.1-py3-none-any.whl .

i've also tried the following , but got the same sha hash errors with :
pip install pywebview --no-cache-dir
pip install pywebview==5.1 --no-cache-dir
pip install pywebview==5.1.0 --no-cache-dir
pip install pywebview==5.0.5 --no-cache-dir
pip install pywebview==5.0.4 --no-cache-dir
pip install pywebview==5.0.3 --no-cache-dir
pip install pywebview==5.0.1 --no-cache-dir

but no problems with :
pip install pywebview==4.4.1

my environment :
pip 24.0
Python 3.12.3 [MSC v.1938 64 bit (AMD64)]
Windows 10 64bit 22H2

according to pypa/pip#12679 (comment)
and other sources , such sha hash problems could happen ,
because of security software ( e.g. : firewall , security-ai , ... ) on the
internet-connenction somehow changing some files during downloads .

using another internet-connection solved this issue for me .
