Question

我试图运行一个简单的gulp-sass任务，但我收到了这个错误：

[22:42:14] Starting 'sass'...
[22:42:14] Finished 'sass' after 10 ms

 events.js:72
    throw er; // Unhandled 'error' event
          ^

我在全局和本地安装gulp作为开发人员依赖。这是我的任务：

var gulp = require("gulp"),
sass = require("gulp-sass");

gulp.task("sass", function(){
    gulp.src('assets/sass/*.scss')
        .pipe(sass())
        .pipe(gulp.dest('assets/css'))
});

Answer 1

错误并不是那么清楚，就像Exception被错误的链接抛出一样（未找到资源）

Answer 2

是的，这是正确的。只要找不到资源，就会抛出错误。我写了一个函数来防止在我的文件中出现这种情况。运行“npm install fs --save”。然后将其添加到您的gulpfile

var fs = require('fs');
var validateResources = function (resources) {
  resources.forEach(function (resource) {
    if (!fs.existsSync(resource)) {
      throw resource + " not found!";
    }
  });
};

有了这个，你在某种程度上是安全的。
