[运行任务时，出现以下错误：
SyntaxError in plugin "gulp-babel"
Message:
/Users/******/Repos/******/src/scripts/config/index.js: Unexpected export specifier type
> 1 | export * as constants from './constants';
^^^^^^^^^^^^^^
我不确定为什么会这样，因为我正在运行所需的插件以允许ES6导入/导出，所以我认为...
。babelrc

"@babel/preset-env",

package.json-我已经列出了完整列表，其中大多数可能无关紧要，但以防万一已知的软件包冲突。

任何帮助表示赞赏-我真的为此感到茫然。
（使用节点v9.11.2）
问题是，我们通过“ foo”支持添加了export * as ns默认为@ babel / parser（在＃10521中），而不是@ babel / preset-env。
作为解决方法，您可以启用@ babel / plugin-proposal-export-namespace-来自您的配置。
因此，将@babel/plugin-proposal-export-namespace-from添加到您的.babelrc和dev依赖项中，您应该就可以了！
看来最终这将内置到预设环境中，因此您不必使用插件。
