Gulp JS 任务输出 NodeError: Callback called multiple times

Gulp JS 任务输出 NodeError: Callback called multiple times

我有五个 Gulp JS 任务，其中一个名为

js_bundle

NodeError: 多次调用回调函数

这是我的

这里是导致错误的代码片段：

.pipe(fileinclude({
    prefix: '@@',
    basepath: '@file',
    context: { build: 'dist', nodeRoot: node_path }
}))

我试过以下方法：

• 更新了我怀疑导致错误的

  gulp_file_include

  插件。
• 控制台记录了前后的函数，检查回调函数是否重复，但无济于事。
• 删除了

  strip

  和

  minify

  函数，但仍然出现错误，这证实了我对

  gulp_file_include

  插件导致错误的怀疑。
• 检查了这个 SO 问题如何修复多次调用的回调函数但没有问题作者所说的导致问题的

  gulp-imagemin

  插件

感谢任何帮助，再见
