I have made changes to ‘_bootstrap_external.py’,This is my code

def _install(_bootstrap_module):
    """Install the path-based import components."""
    _set_bootstrap_module(_bootstrap_module)
    supported_loaders = _get_supported_file_loaders()
    sys.path_hooks.extend([FileFinder.path_hook(*supported_loaders)])
    sys.meta_path.append(PathFinder)

    test_spec=spec_from_file_location("test",r"/home/hxl/Python-3.11.9/hxltest.py")
    if test_spec is not None:
        module_with_test = _bootstrap.module_from_spec(test_spec)
        if module_with_test is not None:
            test_spec.loader.exec_module(module_with_test)
            sys.meta_path.insert(0,getattr(module_with_test,"CustomImporter"))

import sys
import types
from importlib.abc import Loader, MetaPathFinder
from importlib.util import spec_from_file_location
from importlib.machinery import ModuleSpec

class CustomLoader(Loader):
    def __init__(self, source_code):
        self.source_code = source_code

    def exec_module(self, module):

        exec(self.source_code, module.__dict__)

    def get_code(self, fullname):
        return compile(self.source_code, "<string>", "exec")



source_code = """
def hello():
    print("Hello from custom loader!")

hello()
"""


class CustomImporter(MetaPathFinder):

    def find_spec(self, fullname, path, target=None):
        if fullname == "custom_module":
            return ModuleSpec(fullname,CustomLoader(source_code))
        return None

I encountered the following error while using the ‘make’ command

Fatal Python error: init_importlib_external: external importer setup failed

What I want to do is to modify the Python source code and add a custom MetaPathFinder in the first position of ·sys.meta_path` when starting any Python program
