如果我使用 winston-daily-rotate-file,我会收到 Winston 日志记录错误。 当我使用 webpack 构建应用程序时,没有错误,但是当我执行下面的构建时,出现错误(堆栈跟踪):
/app/web-app/server/node_modules/winston/lib/winston/logger.js:307
throw ex;

我的温斯顿配置是:
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',
prettyPrint: true,
handleExceptions: true,
json: false,
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;
我在 aws elasticbeanstalk 上发生了完全相同的错误、行号和所有内容。
它在本地工作,但是当它到达aws时,发生错误,因为节点正在以用户“webapp”运行。看起来该用户没有权限将文件写入 /var/log,这看起来很奇怪。所以我将其更改为登录到 /tmp 并且错误消失了。注意:确保日志文件归 webapp(或运行节点应用程序的任何用户)所有,否则错误将持续存在。
在我的例子中,应该保存日志的目录不存在,这导致了错误。
在我们的例子中,存储 PM2 日志的目录已耗尽。一旦我们清理了空间,错误就消失了。
