错误[ERR_STREAM_DESTROYED]：使用Winston销毁流后无法调用写入

问题描述

如果我使用 winston-daily-rotate-file ，则Winston日志记录会出现错误。当我使用 webpack 构建我的应用程序时，没有错误，但是当我执行我的构建时，下面的错误来了（堆栈跟踪）：

/app/web-app/server/node_modules/winston/lib/winston/logger.js:307
      throw ex;
      ^

我的winston配置是：

const winston = require('winston');
const DailyRotateFile = require('winston-daily-rotate-file');

var options = {
    file: {
        zippedArchive: true,prettyPrint: true,json: false,filename: `/app/web-app/server/logs/server_logs/server.log`,datePattern: '.yyyy-MM-dd',handleExceptions: true,maxsize: '10m',// 10MB
        maxFiles: 5,colorize: false,},console: {
        level: 'debug',colorize: true,};

var logger = new winston.createLogger({
    transports: [
        // new winston.transports.DailyRotateFile(options.file),new DailyRotateFile(options.file),new winston.transports.Console(options.console),],exitOnError: false,// do not exit on handled exceptions
});

logger.stream = {
    write: message => {
        logger.info(message);
    },};

module.exports = logger;

解决方法

我在aws elasticbeanstalk上发生了完全相同的错误，行号和所有其他事情。

它在本地工作，但是到aws时，发生了错误，因为节点以用户“ webapp”的身份运行。似乎该用户无权将文件写入/ var / log，这似乎很奇怪。所以我将其更改为登录到/ tmp，错误消失了。注意：请确保日志文件归webapp拥有（或任何运行节点应用程序的用户），否则错误将持续存在。
