Python利用Pyexecjs执行JS文件，编码格式错误问题

报错:

 UnicodeDecodeError: ‘gbk’ codec can’t decode byte 0xa8 in position…

1.使用functools相当于hook encoding参数

import subprocess
from functools import partial  # 用来固定某个参数的固定值

subprocess.Popen = partial(subprocess.Popen, encoding='utf-8')
# 解决execjs执行js时产生的乱码报错，需要在导入execjs模块之前，让Popen的encoding参数锁定为utf-8
import execjs

2.直接点击subprocess，搜索pass_fds=()，下面的这个encoding参数就是报错点：

3.在需要执行js的方法上添加装饰器

import subprocess
from contextlib import contextmanager
from unittest.mock import patch


@contextmanager
def patched_popen_encoding(encoding='utf-8'):
    original_popen_init = subprocess.Popen.__init__

    def new_popen_init(self, *args, **kwargs):
        kwargs['encoding'] = encoding
        original_popen_init(self, *args, **kwargs)

    with patch.object(subprocess.Popen, '__init__', new_popen_init):
        yield
