TypeError: appenderModule.configure is not a function #1411

Node.js: v16.16.0 Nuxt: 2.15.8 log4js: 6.9.1

Hi.

I am triying to use log4js in Nuxt，it is work, but it's throwing an error: TypeError: appenderModule.configure is not a function.

this is my log4js.js:

// const log4js = require("log4js");
// import log4js from 'log4js';
import * as log4js from "log4js";

const config = {
    appenders: {
        info: {
            info: { type: "file", filename: "logs/info.log" },
        },
    },
    categories: {
        default: { appenders: ['debug', 'info', 'error'], level: 'info' },
    },
};
log4js.configure(config);

export default log4js;

I tried three different approaches:
Approach 1: const log4js = require("log4js");
Approach 2: import log4js from 'log4js';
Approach 3: import * as log4js from "log4js";
But all of them resulted in the above-mentioned error.

usage:

<template>
    <div>ttt6666888</div>
</template>

<script>
import log4js from './log4js';


export default {
    name: "IndexPage",
    asyncData() {

      const logger = log4js.getLogger('info');
      logger.info('info~~~');

        return {
          test: 111
        }
    }
}
</script>

error is:

TypeError: appenderModule.configure is not a function
    at eval (index.js:117:29)
    at Object.onlyOnMaster (clusteringBrowser.js:13:50)
    at createAppender (index.js:112:21)
    at getAppender (index.js:68:20)
    at eval (index.js:147:7)
    at Array.forEach (<anonymous>)
    at setup (index.js:139:33)
    at eval (configuration.js:51:35)
    at Array.forEach (<anonymous>)
    at Object.configure (configuration.js:51:13)

But when I directly use log4js in a component, it works and doesn't throw an error.
my component:

<template>
    <div>test11</div>
</template>

<script>
const log4js = require("log4js")

export default {
    name: "IndexPage",
    asyncData() {
        log4js.configure({
            appenders: {
                out: { type: "stdout" },
                app: { type: "file", filename: "logs/app.log" }
            },
            categories: {
                default: { appenders: ["out", "app"], level: "debug" }
            }
        })
        const logger = log4js.getLogger("cheese")

        logger.info("Cheese is Comté.")
        logger.error("Cheese is too ripe!")
    }
}
</script>

Do you have any solutions for this error?

hi! i have the same issue with log4js in vue3 and electron.

import log4js from "log4js";

export default {
  install: (app, options) => {
    const logConfig = {
      appenders: {
        dateFileLog: {
          category: "log_date",
          type: "dateFile",
          filename: "./logs/log",
          alwaysIncludePattern: true,
          keepFileExt: true,
          pattern: "yyyy-MM-dd.log",
        },
        allFileLog: {
          type: "file",
          filename: "./logs/log.log",
          keepFileExt: true,
          maxLogSize: 1024 * 1024 * 100,
          backups: 3,
        },
      },
      categories: {
        default: { appenders: ["dateFileLog"], level: "info" },
        allFile: { appenders: ["allFileLog"], level: "debug" },
      },
    };
    log4js.configure(logConfig);
    app.config.globalProperties.$logger = log4js.getLogger();
  },
};

    const config = {
      appenders: {
        outfile: { type: 'file', filename: 'cheese.log' },
      },
      categories: {
        default: { appenders: ['outfile'], level: 'trace' },
      },
    }

The above configuration will cause an error, however the following configuration will not

    const config = {
      appenders: {
        console: { type: 'console' },
      },
      categories: {
        default: { appenders: ['console'], level: 'trace' },
      },
    }

I debug code by vscode， I found cause.
