从报错信息来看，主要是日志输出时碰到了编码问题（UnicodeEncodeError: 'gbk' codec can't encode character '\u2705'...），再加上后面还有一些版本不兼容的提示。下面分点解释原因和解决办法：

1. 最直接的错误：日志编码不兼容（GBK → UTF-8）

Python 的logging模块默认会用系统的编码（Windows 下常是'gbk'）往控制台写日志。而你的代码里用了 Unicode 字符（比如✅这个 emoji 或特殊符号），gbk编码不认识这种字符，就会抛出UnicodeEncodeError。

解决思路：

让 Python 日志用 UTF-8 编码输出，而不是系统默认的 GBK。

做法有很多种，比较常见的是在程序开头（或配置日志的地方）加上下面这样的代码，强制让标准输出的编码变成 UTF-8：

我的logging是自定义的：在项目根目录下的logger.py  内容是 import logging
import os
class CustomLogger:
    def __init__(self, name, log_file, level=logging.INFO):
        self.logger = logging.getLogger(name)
        self.logger.setLevel(level)
        # 创建一个文件处理器，写入日志文件
        file_handler = logging.FileHandler(log_file)
        file_handler.setLevel(level)
        # 创建一个控制台处理器，输出到控制台
        console_handler = logging.StreamHandler()
        console_handler.setLevel(level)
        # 定义日志格式
        formatter = logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s')
        file_handler.setFormatter(formatter)
        console_handler.setFormatter(formatter)
        # 将处理器添加到 Logger 对象
        self.logger.addHandler(file_handler)
        self.logger.addHandler(console_handler)
    def get_logger(self):
        return self.logger  。要怎么改 “让 Python 日志用 UTF-8 编码输出，而不是系统默认的 GBK。”

你的CustomLogger类是自定义的日志封装，它内部使用了 Python 标准库的logging模块，并分别添加了一个文件处理器（FileHandler）和一个控制台处理器（StreamHandler）。...
