无法运行 gulp 任务

Question

我正在尝试运行一项简单的 gulp-sass 任务，但出现此错误：

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

 events.js:72
    throw er; // Unhandled 'error' event
          ^
   Error: File not found with singular glob

我在全局和本地安装了 gulp 作为开发依赖项。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

错误不是很清楚，顺便说一句 Exception 被错误抛出 link（找不到资源）

Answer 2

是的，没错。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发生这种情况。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，你就会安全一些。
