use

pip uninstall lxml

Then run again

python -m uiautomator2 init

initialized successfully

2, start weditor, given as follows:

python -m weditor

    raise NotImplementedError

NotImplementedError

In the Folder Quick Search: asyncio.py, add the following three lines of code in the py, and then you can re-run the python -m weditor

import sys

if sys.platform == 'win32':
　　asyncio.set_event_loop_policy(asyncio.WindowsSelectorEventLoopPolicy())

As follows:

import concurrent.futures
import functools

from threading import get_ident
from tornado.gen import convert_yielded
from tornado.ioloop import IOLoop, _Selectable

import asyncio

import typing
from typing import Any, TypeVar, Awaitable, Callable, Union, Optional



import sys

if sys.platform == 'win32':
    asyncio.set_event_loop_policy(asyncio.WindowsSelectorEventLoopPolicy())



if typing.TYPE_CHECKING:
    from typing import Set, Dict, Tuple  # noqa: F401

_T = TypeVar("_T")


class BaseAsyncIOLoop(IOLoop):
    def initialize(  # type: ignore
        self, asyncio_loop: asyncio.AbstractEventLoop, **kwargs: Any
    ) -> None:
        self.asyncio_loop = asyncio_loop
        # Maps fd to (fileobj, handler function) pair (as in IOLoop.add_handler)
