运行gulp任务时,出现以下错误:
When running my gulp task, I get the following error:
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,或者我想...
I'm not sure why this is as I am running the required plugins to allow ES6 imports/exports, or so I thought...
.babelrc

package.json - I've included the full list, most of it will probably be irrelevant but just in case there are any known package conflicts.

Any help appreciated - I'm really at a loss for this one.

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.
The problem is that we added export * as ns from "foo" support by default to @babel/parser (in #10521) but not to @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.
As a workaround, you can enable @babel/plugin-proposal-export-namespace-from in your config.
因此,将@babel/plugin-proposal-export-namespace-from添加到您的.babelrc和dev依赖项中,您就可以了!
So add @babel/plugin-proposal-export-namespace-from to your .babelrc and dev dependencies and you should be OK!
看起来最终它将被内置到预设环境中,因此您不必使用插件.
It looks like eventually this will be built into the preset-env so you won't have to use a plugin.
