在AWS Amplifiy上构建失败而没有错误消息

如何解决在AWS Amplifiy上构建失败而没有错误消息

我想使用Amplify部署React应用。在本地，该应用程序可以正常运行。但是，在AWS上放大会失败，但不会返回任何错误消息。

此行Executing command: node ./node_modules/gulp/bin/gulp.js在构建失败之前运行了20分钟。

我的gulpfile.js：

'use strict';

// dependencies
var gulp = require('gulp');
var sass = require('gulp-sass');
var minifyCSS = require('gulp-clean-css');
var uglify = require('gulp-uglify');
var rename = require('gulp-rename');
var changed = require('gulp-changed');



///////////////

var SCSS_SRC = './src/Assets/scss/**/*.scss';
var SCSS_DEST = './src/Assets/css';

// Compile SCSS

function compile_scss() {
    return gulp.src(SCSS_SRC)
        .pipe(sass().on('error',sass.logError))
        .pipe(minifyCSS())
        .pipe(rename({ suffix: '.min' }))
        .pipe(changed(SCSS_DEST))
        .pipe(gulp.dest(SCSS_DEST));

// detect changes in SCSS

function watch_scss() {

// Run tasks

gulp.task('default',watch_scss);

exports.compile_scss = compile_scss;
