我很难分辨出我的吞咽任务失败的原因以及原因。如何增加默认堆栈跟踪?

解决方案

添加评论和管道工:


  1. 添加这个帮手方法:

    log =(msg) - >
    console.log msg
    #你会收到乙烯基文件为块
    transform =(file,cb) - >
    #读取和修改文件内容
    #file.contents = new Buffer(String (file.contents)+'一些修改过的内容');

     #如果出现错误,只需作为第一个参数传递这里
    cb(null,file);

    #返回地图将导致您的变换函数被称为
    #您收到的块(文件)。当这个流
    #收到一个'结束'信号时,它也会结束。

    #此外,您还想在其他地方要求 event-stream
    return eventStream.map(transform);


  2. 任务中的步骤之间的管道日志方法:

    gulp.task'myTask', - >
    gulp.src myCss,
    base:myBase
    .pipe log获得了css文件!
    .pipe concat'app.css'
    .pipe logconcated css !!


这是用coffeescript编写的,你可以在这里把它变成javascript:


  1. 创建catch错误帮助器方法:

    catchError =(err) - >
    plugins.util.beep()#;
    console.log err


  2. 将plumber添加到插件:

    gulp.task' myTask', - >
    gulp.src myCss,
    base:myBase
    .pipe plugins.plumber
    errorHandler:catchError
    .pipe log获得了css文件!
    .pipe concat'app.css'
    .pipe logconcated css !!


完成! :)

  at Socket.<anonymous> (child_process.js:969:11)
  at Socket.emit (events.js:95:17)

It's hard for me to tell where my gulp task is failing and why. How can I increase the default stack trace?

解决方案

Add comments and plumber:

  1. Add this helper method:

    log = (msg) -> console.log msg # you're going to receive Vinyl files as chunks transform = (file, cb) -> # read and modify file contents # file.contents = new Buffer(String(file.contents) + ' some modified content');

    # if there was some error, just pass as the first parameter here
    cb(null, file);
    

    # returning the map will cause your transform function to be called # for each one of the chunks (files) you receive. And when this stream # receives a 'end' signal, it will end as well. # # Additionally, you want to require the event-stream somewhere else. return eventStream.map(transform);

  2. pipe thw log method between steps in a task:

    gulp.task 'myTask', -> gulp.src myCss, base: myBase .pipe log "Got css files!" .pipe concat 'app.css' .pipe log "concated css!!"

this is written in coffeescript, you can turn it to javascript here:http://js2coffee.org/

  1. create a catch error helper method:

    catchError = (err) -> plugins.util.beep() # ref; console.log err

  2. add plumber to plugins:

    gulp.task 'myTask', -> gulp.src myCss, base: myBase .pipe plugins.plumber errorHandler: catchError .pipe log "Got css files!" .pipe concat 'app.css' .pipe log "concated css!!"

Done! :)
