Gulp注入方法抛出内存不足异常

Question

我正在使用gulp-inject插件将html文件注入anothe html fiile中。我已经使用以下任务来做到这一点。

gulp.task("inject:component:html", () => {
let paths = getSelectedComponentHtml();

var sources = gulp.src([path.join(CONFIG.dest, CONFIG.downloads, downloadDir, CONFIG.componentDownloadPath + 'js/ui-pattern.js'), path.join(CONFIG.dest, CONFIG.downloads, downloadDir, 'uxpl/components/ui-pattern.css')]);
var source = '';
var visitedDirectories = [];
if (takeHeaderHtml) {
    // isHeader = true;
    source = gulp.src(CONFIG.site + "/components/header-navigation.html");
} else {
    // isHeader = false;
    source = gulp.src(CONFIG.componentsSrc + '/index.html');
}
// var sources = gulp.src([path.join(CONFIG.dest, CONFIG.downloads, downloadDir, CONFIG.componentDownloadPath + 'js/ui-pattern.js'), path.join(CONFIG.dest, CONFIG.downloads, downloadDir, 'uxpl/components/ui-pattern.css')]);
var stream = source
    .pipe(inject(gulp.src(paths), {
        starttag: '<!-- inject:{{ext}} -->',

        transform: function (filePath, file, i, length) {
            let contents = '';
            try {
                console.log('In transform method');
                var url = filePath;
                var fileName = url.substring(url.lastIndexOf('/') + 1);
                console.log("arguments====" + arguments);

                var snippet = file.contents.toString('utf8');
                console.log("snippet====");

                contents = snippet;
                console.log("contents====");

                // return file contents as string
                let snipp = snippet.match(/\<\!--\s*html\s*:/gm);
                if (snipp && snipp.length) {
                    let snipp = snippet.substring(snippet.indexOf('<!--html:') + 9, snippet.indexOf('html!-->'));
                    contents = fs.readFileSync(snipp.trim(), 'utf8');
                    console.log("contents reading====");
                }
                let folderName = filePath.replace(fileName, '');
                console.log("folderName replace====");

                if (visitedDirectories.length == 0) {
                    contents = '<div class="showcase">\n' + contents + '\n';
                    console.log("In iff====");
                    visitedDirectories.push(folderName);
                } else if (visitedDirectories.indexOf(folderName) === -1) {
                    contents = '</div>\n <div class="showcase">\n' + contents + '\n';
                    console.log("In else====");
                    visitedDirectories.push(folderName);
                }
                if (i == length - 1) {
                    contents = contents + '</div>\n<div class="showcases-padding"></div>';
                }
                console.log("just before return ======");

            }catch(e){
                console.log("in catch block===>>"+e);
            }
            return contents.toString('utf8');
        }
    }))

    .pipe($.replace('/vendor', '../../../../vendor'))
    .pipe($.replace('/assets', '../../../../assets'))
    .pipe(gulp.dest(path.join(CONFIG.dest, CONFIG.downloads, downloadDir, CONFIG.componentDownloadPath)));
console.log("just before return stream ======");

return stream;

}）;

一切正常，但无法完成trasnform方法。

直到** console.log("just before return stream ======"); **为止，所有日志都可以正常工作，但是此后，我出现以下错误。

我尝试给出--max-old-space-size = 4096，但仍然出现相同的错误。 如果有人有任何想法，请检查此问题。
