var log4js = require ("log4js");
var log4js_config = require (". / log4js.json");
log4js.configure (log4js_config);

console.log ("log_start start!");

var LogFile = log4js.getLogger ("log_file");

LogFile.trace ("This is a Log4js-Test");
LogFile.debug (" We Write Logs with log4js");
LogFile.info ("You can find logs-files in the log-dir");
LogFile.warn (" log-dir is a configuration-item in the log4js.json");
LogFile.error ("In This Test log-dir is:"/ logs/log_test/"");

console.log ("log_start end!");

what result do you expect? What is the error message actually seen?

first create the / var/log/graduation-alfred-jade-log/weibo folder manually.
then run your node service, and when there is an output code that executes to your schedule, there will be a log in the folder.

Root directory
node log4js
is it so complicated to hit a log? look at a demo and perfect the logic you need. 
   let fs = require('fs');  //fs
     
    let options = {
      flags: 'a',     // append
      encoding: 'utf8',  // utf8
    };
     
    let stdout = fs.createWriteStream('./stdout.log', options);
     
    // logger
    let logger = new console.Console(stdout);
     
    for (let i = 0; i < 100; iPP) {
      logger.log(`log message ${i}`);
    }
    // 100log message + i
    //,fs index.js  cmd =>  node index.js

log is recorded by yourself through the code. this module can see the record of node.js operation. what is the operation record?
