[Python] ModuleNotFoundError: 'encodings' when building python3.14 from scratch

I’m experiencing an error repeatedly when trying to build Python from the main branch of the official repository

I have a Python 3.13.7 version in ~/.pyenv/versions already. Clang version = 19.1.7

System python version = 3.10.12

System = Ubuntu 22.04.5 LTS

Now, I cloned the main branch, checked out a new branch, and tried to build Python from scratch using the following commands.

./configure CC=clang --prefix=$HOME/python3.14_1 --enable-optimizations --with-lto --enable-experimental-jit make -j$(nproc) With this make command, I’m getting the following error:

The entire link of the error: Warp

I tried checking the following command and getting a runtime state error:

./_bootstrap_python -S -c "import encodings; print(encodings.__file__)" \
PYTHONPATH=./Lib
Fatal Python error: Run filename expected
Python runtime state: preinitialized


I tried the 3.14 branch from the repository but even that’s producing the same error. Is it some issue with some config that I need to change or a known issue? I don’t see much chat about this issue online, though. Let me know if you need any extra info to debug this issue. Any input is highly appreciated!

Thanks!
