推荐答案

主要错误是在使用 ES6 格式时产生的.使用 gulp-uglify-es 模块而不是 'gulp-uglify' 来克服这个错误.

The main error is generated when you're using ES6 format. Use the gulp-uglify-es module instead of 'gulp-uglify' to overcome this error.

var uglify = require('gulp-uglify-es').default;

注意:gulp-uglify-es 不再维护.您可能想使用 terser/gulp-terser 代替:

Note: gulp-uglify-es is no longer being maintained. You may want to use terser/gulp-terser instead:
