Error after update winston to version 3.2.1. TypeError: self._addDefaultMeta is not a function

Question

我将 winston 更新到版本 3.2.1 后，尝试热重新编译项目时出现错误（当我的项目启动并进行更改时）。

我尝试将所有依赖项更新到最新版本，但这没有帮助。看来 webpack-hot-middleware 不能在最新版本的 winston 上正常工作。

如能提供解决此问题的建议，我将不胜感激。

错误：

记录器配置：

const winston = require('winston');

const transports = [];

const alignColorsAndTime = winston.format.combine(
  winston.format.timestamp({
    format: 'HH:MM:ss:SS DD.MM.YY',
  }),
  winston.format.printf(
    info => `${info.timestamp} ${info.level}:${info.message}`,
  ),
);

/**
 * Console transporter
 */
transports.push(new winston.transports.Console({
  level: config.logging.console.level,
}));

const logger = winston.createLogger({
  level: 'debug',
  transports,
  format: winston.format.combine(winston.format.colorize(), alignColorsAndTime),
  exitOnError: false,
});

module.exports = logger;

依赖版本：

winston@3.2.1
webpack-hot-middleware@2.25.0
webpack@4.41.2

查看此线程以获取解决方案。 https://github.com/winstonjs/winston/issues/1591

将记录器显式绑定回其方法

例如：

const logger = winston.createLogger({
  transports: [
    new winston.transports.Console()
  ]
}); 

logger.info.bind(logger)
