推荐答案

似乎与Gulp V4有关，有两个选择:

It seems to be related to the Gulp V4, there's two options:

• 将您的代码更新为V4(相关文章)

OR

• 降级gulp版本

要降级，您需要将package.json更新为

To downgrade you need to update your package.json with

"gulp": "^3.9.1",

然后删除node_module文件夹并重新安装npm软件包

And then remove node_module folder and reinstall npm packages

rm -rf node_modules
npm install
