离子1：Gulpfile错误 - ＆＃39; labsass＆＃39;绑定未找到

Question

我收到此错误。

There is an error in your gulpfile: 
Error: `libsass` bindings not found. Try reinstalling `node-sass`?
at getBinding (/Users/SubjectiveEffect/node_modules/gulp-sass/node_modules/node-sass/lib/index.js:22:11)
at Object.<anonymous> (/Users/SubjectiveEffect/node_modules/gulp-sass/node_modules/node-sass/lib/index.js:188:23)
at Module._compile (module.js:570:32)
at Object.Module._extensions..js (module.js:579:10)

at Function.Module._load (module.js:438:3)
at Module.require (module.js:497:17)
at require (internal/module.js:20:19)

我已经重新安装了node-sass，npm，node，ionic，everything。

知道发生了什么事吗？我看到很多人都有这方面的问题，但似乎没有解决方案......

因此，离子服务不再起作用了。应用程序几乎已准备好发布，但......

我的gulfile.js：

var gulp = require('gulp');
var gutil = require('gulp-util');
var bower = require('bower');
var concat = require('gulp-concat');
var sass = require('gulp-sass');
var minifyCss = require('gulp-minify-css');
var rename = require('gulp-rename');
var sh = require('shelljs');

var paths = {
  sass: ['./scss/**/*.scss']
};

gulp.task('default', ['sass']);

gulp.task('sass', function(done) {
  gulp.src('./scss/ionic.app.scss')
    .pipe(sass())
    .pipe(gulp.dest('./www/css/'))
    .pipe(minifyCss({
      keepSpecialComments: 0
    }))
    .pipe(rename({ extname: '.min.css' }))
    .pipe(gulp.dest('./www/css/'))
    .on('end', done);
});

gulp.task('watch', function() {
  gulp.watch(paths.sass, ['sass']);
});

gulp.task('install', ['git-check'], function() {
  return bower.commands.install()
    .on('log', function(data) {
      gutil.log('bower', gutil.colors.cyan(data.id), data.message);
    });
});

gulp.task('git-check', function(done) {
  if (!sh.which('git')) {
    console.log(
      '  ' + gutil.colors.red('Git is not installed.'),
      '\n  Git, the version control system, is required to download Ionic.',
      '\n  Download git here:', gutil.colors.cyan('http://git-scm.com/downloads') + '.',
      '\n  Once git is installed, run \'' + gutil.colors.cyan('gulp install') + '\' again.'
    );
    process.exit(1);
  }
  done();
});
