The package pycparser does not have an official version 3.11 (or 3.0) released on PyPI. The latest official version is in the 2.x range (e.g., 2.23). Specifying a non-existent major version like 3.11 will cause installation failures or introduces a severe security risk of dependency confusion/malicious package injection if fetched from an untrusted index.

I appreciate the clarification, but I must reiterate my concern regarding the versioning of pycparser. According to the official PyPI repository for pycparser, the latest stable version is 2.23. There are no official 3.x releases listed in the project history. The presence of 3.0 and 3.11 in the dependency files is highly irregular and could indicate a potential dependency confusion attack or the use of a malicious package. I strongly recommend verifying the source of these versions before proceeding with this update, as this remains a critical security concern.
