すでに答えがあるかもしれませんが、まだ見つけていません。つまり、gulp 経由で更新したいプラグイン (zxing) があります。私のgulpタスク(extern)は次のようになります:

import {nodeModules, scriptsDir} from './paths';
import zxingPkg from '../node_modules/@zxing/library/package.json';
import {src, series, dest} from 'gulp';
import rename from 'gulp-rename';
import replace from 'gulp-replace';
import run from 'gulp-run';
let oldVersion = zxingPkg.version;
let newVersion = '0';
import fs from 'fs';

const paths = {
    scripts: {
        srcZxing: `${nodeModules}/@zxing/library/umd/index.min.js`,
        destZxing: scriptsDir,
    }
}

const zxingTask = () => {
    return src(paths.scripts.srcZxing)
        .pipe(rename(`zxing.${zxingPkg.version}.min.js`))
        .pipe(dest(paths.scripts.destZxing));
}

function update() {
    return run('npm update @zxing/library').exec();
}

function checknew() {
    var obj = JSON.parse(fs.readFileSync('./node_modules/@zxing/library/package.json', 'utf8'));
    newVersion = obj.version;
    if (newVersion > oldVersion) {
        return src('.')
            .pipe(series(copyIt, renameInFiles))
            .pipe('.');
    } else {
        return src('.')
            .pipe(console.log(`${newVersion} == ${oldVersion}`))
            .pipe(dest('.'));
    }
}

function copyIt() {
    console.log('copy');
    return src(`${paths.srcZxing}`)
        .pipe(dest(`${paths.destZxing}/zxing.${newVersion}.min.js`));
}

function renameInFiles() {
    console.log(`zxing.${oldVersion}.min.js zxing.${newVersion}.min.js`)
    return src('./src/appl/framework/functions/**/*')
        .pipe(replace(`zxing.${oldVersion}.min.js`, `zxing.${newVersion}.min.js`))
        .pipe(dest('./src/appl/framework/functions/**/*.(php|phpi)'))
}

module.exports = series(update);

gulpfile.babel.js は次のようになります。

import zxingTask from './gulptasks/zxing';

...

// zxing => /scripts/zxing.{version}.min.js
const zxing = () => {
    return zxingTask();
}

exports.zxing = zxing;

次のエラーが表示されます。

[08:53:14] Starting 'zxing'...
[08:53:14] Starting 'update'...
[08:53:14] 'update' errored after 1.26 ms

エラーがわかりません。私はそれを完全に間違っていますか、それともタスクを実行するのに良い方法ですか?
