問題描述

我正在創建一個在某些情況下可能會失敗的 gulp 任務.

gulp.task('favicon', function () {嘗試 {require('child_process').execSync('icotool --version');} 捕捉( e ) {var err = new Error('生成 favicon 需要 Unix bash 和 icotool');拋出錯誤；}返回 gulp.src('', {read: false}).管道(外殼(['./generate-favicon.sh']));});

當通過 gulp 運行我的任務并遇到錯誤時，該錯誤將呈現得相當難看.我想以一種方式呈現錯誤，例如，jslint gulp-util 的 PluginError.

它實際上只是在其中創建一個 PluginError 并拋出它，但這似乎不太正確.另一個不太好的解決方案是設置

err.showStack = false;

至少有更好的錯誤輸出.gulp.task.Error 會很好.

據我所知，從 gulp 中拋出錯誤并不是很好.但是我發現了這個我曾經為我工作的博客條目.

編輯:gulp-util已棄用.相反，請使用 plugin-error 包.p>

我的例子:

var gulp = require('gulp');var error = require('plugin-error');gulp.task('部署'，函數(cb){if(typeof(specialId) === '未定義') {var err = new PluginError({插件:'部署'，消息:'specialId 為空.'});}}

I am creating a gulp task which might fail under certain circumstances.

gulp.task('favicon', function () {
  try {
    require('child_process').execSync('icotool --version');
  } catch( e ) {
    var err = new Error( 'Unix bash and icotool required for generating favicon' );
    throw err;
  }

  return gulp.src('', {read: false})
    .pipe(shell([
      './generate-favicon.sh'
    ]));
});

When running my task via gulp and running into the error, the error will be presented rather ugly. I would like to present the error in a way as it is done by e.g. jslint gulp-util's PluginError.

It actually works to just create a PluginError there and throw it but that doesn't seem quite right. Another solution not that nice would be to set

err.showStack = false;

for at least a little nicer error output. A gulp.task.Error would be nice.

From what I've seen its not great to throw an error from gulp. But I found this blog entry that I used to work for me.

Edit: gulp-util has been deprecated. Instead, use the plugin-error package.

My Example:

var gulp = require('gulp');
var error = require('plugin-error');
gulp.task('deploy', function(cb) {
  if(typeof(specialId) === 'undefined') {
    var err = new PluginError({
      plugin: 'deploy',
      message: 'specialId is empty.'
    });
  }
}
