Webpack 再生器运行时间未定义为Gulp#x2B；网页包+；巴别塔

我试图将ES7“异步等待函数”与bable 7+webpack+gulp一起使用，但出现以下错误：未定义regeneratorRuntime

我找到了几个解决方案，但都不起作用：我尝试了core js和@babel/plugin transform runtime，甚至babel polyfill，根据babel docs的说法，babel polyfill是不推荐的，但无法解决这个错误

以下是我的最新配置文件：

    }

[...] 


    getResults() {
        async function searchResults() {
            try {            
                let postsResponse = await fetch(`http://localhost:3000/wp-json/v2/posts?search=${this.searchField.value}`);
                let posts = await postsResponse.json();
                console.log(posts);                                
            }
            catch (err) {
                this.resultsDiv.innerHTML = "Oops! an error occurred, please, try again later";
                console.log(err);
            }            
        }

        searchResults();


        this.resultsDiv.innerHTML = "Search results will go here";
    }
}

export default Search;

因此，经过两天的搜索和测试，我终于解决了这个问题： 1.干净的网页包与推荐的配置完美配合：

我将所有webpack和babel相关软件包更新为最新的稳定版本

我的吞咽文件有问题。所以我通过网页包流改变了网页包的使用。之前：

之后：

 const webpack = require('webpack-stream');
 gulp.task('scripts', function() {
   return gulp.src(settings.themeLocation + "js/scripts.js")
     .pipe(webpack( require('./webpack.config.js') ))
     .pipe(gulp.dest(settings.themeLocation + "js"));
 });
