GulpUglifyError：无法通过Browserify缩小JavaScript错误
我将这个脚本与Browserify + Babel捆绑在一起，如下所示：
function buildJs() {
let bopts = {
paths: [
`${SRC}/js`,
'./config'
],
debug: !isProduction
};
let opts = Object.assign({}, watchify.args, bopts);
let b = watchify(persistify(opts));
b.add(`${SRC}/js/index.js`)
.on('update', bundle)
.on('log', gutil.log)
.external(vendors)
.transform(babelify, {
presets: ["es2015", "react"],
plugins: [
"syntax-async-functions",
"transform-regenerator",
"transform-class-properties",
"transform-decorators-legacy",
"transform-object-rest-spread",
"transform-react-jsx-source",
staticFs
]
})
.transform(browserifyCss, { global: true });
function bundle() {
let stream = b.bundle()
.on('error', swallowError)
.on('end', () => {
gutil.log(`Building JS:bundle done.`);
})
.pipe(source('bundle.js'))
.pipe(streamify(uglify()));
return stream.pipe(gulp.dest(`${DIST}/js`));
}
return bundle();
}
这只是浏览 - > babelify - > browserify-css - > uglify - > gulp.dest。 但是如果我运行这个任务，它会失败：

只要跳过uglify作品，但我真的需要它。
奇怪的是，结束事件后发生错误。 我尝试使用乙烯基缓冲区，但同样的错误发生。
我找不到任何解决方案，我的每一次尝试都会失败，并显示相同的错误消息。
我错过了什么？ 有没有我错过的东西？
尝试用var替换let ，看看会发生什么。
