gulp-babel在删除node_modules后得到语法错误并再次运行npm install

我在我的gulp构建脚本中有gulp-babel任务，并且它运行良好，直到我删除了node_modules目录并再次运行npm install。它返回gulp-babel在删除node_modules后得到语法错误并再次运行npm install

SyntaxError: j.js: Unexpected token (790:10)

和错误日志指出错误标记为：

789 |  data, 
> 790 |  async = true, 
     |   ^
    791 |  cache = 'no-cache', 
    792 |  method = 'GET', 
    793 |  headers = {},

如果我编译j.js直接CLI babel j.js，不会得到错误信息，并返回编译后的代码如预期。

我一饮而尽任务代码：

const gulp = require('gulp'); 
const { babel } = require('gulp-load-plugins')(); 

gulp.task('babel',() => { 
    return gulp.src([ 
     '.tmp/j.js' 
    ]).pipe(babel()).pipe(gulp.dest('.tmp')); 
});

我.babelrc：

{ 
    "presets" : [ "es2016" ], 
    "plugins" : [ 
     "transform-es2015-arrow-functions", 
     "transform-es2015-object-super", 
     "transform-es2015-parameters", 
     "transform-object-assign", 
     "transform-es2015-block-scoping", 
     "transform-es2015-shorthand-properties", 
     "transform-es2015-block-scoped-functions", 
     "transform-es2015-for-of", 
     "transform-es2015-destructuring", 
     [ "transform-es2015-classes", { "loose" : true } ], 
     [ "transform-es2015-spread", { "loose" : true } ], 
     [ "transform-es2015-template-literals", { "loose" : true } ] 
    ] 
}

    "babel-cli": "^6.14.0",

我来了再回答我的问题。

Babeljs 6.14.0开始支持在ES7中声明的“异步函数”。单词“async”成为编译器的关键字，所以我不能使用“async”作为变量名称。

然后我改变“async = true”为“sync = false”来解决这个问题。

我向github上的Babeljs报告了一个问题。我认为这个问题已经解决了。
