获取:SyntaxError: missing ) 在参数列表之后但无法找出 hulpfile.js 有什么问题 [英] Getting: SyntaxError: missing ) after argument list but can't find out whats wrong with hulpfile.js

问题描述

您好，使用以下 gulp 文件启动gulp default"时出现错误.我无法弄清楚文件有什么问题.

Hi I'm getting an error starting 'gulp default' with the following gulp file. I cannot figure out whats wrong with the file.

var gulp = require('gulp');
var sass = require('gulp-sass');
var sourcemaps = require('gulp-sourcemaps');
var autoprefixer = require('gulp-autoprefixer');
var browserSync = require('browser-sync').create();

var input = './scss/**/*.scss';
var output = './css';

gulp.task('sass', function() {
  return gulp.src(input)
    .pipe(sourcemaps.init())
    .pipe(sass(errLogToConsole: true, outputStyle: 'compressed'))
    .pipe(autoprefixer(browsers: ['last 2 versions', '> 5%', 'Firefox ESR']))
    .pipe(sourcemaps.write())
    .pipe(gulp.dest(output))
    .pipe(browserSync.stream());
});

// Watch files for change and set Browser Sync
gulp.task('watch', function() {
  // BrowserSync settings
  browserSync.init({
    proxy: "mydomain.loc",
    files: "./css/styles.css"
  });

  // Scss file watcher
  gulp.watch(input, ['sass'])
    .on('change', function(event) {
      console.log('File' + event.path + ' was ' + event.type + ', running tasks...')
    });
});

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

我已经重新安装了node，但是所有的包都不能解决问题.

I've allready reinstalled node and all the package won't solve the problem though.

推荐答案

参见 Gulp Sass with errLogToConsole: true 仍然停止我的其他监视任务 和 Gulp 生成的源映射在 Chrome 中不起作用.

不要使用 errLogToConsole，它似乎不再受支持.

Don't use errLogToConsole it doesn't appear to be supported anymore.

.pipe(sass(errLogToConsole: true, outputStyle: 'compressed'))

改成

.pipe(sass({outputStyle: 'compressed'}).on('error', sass.logError))

.pipe(sass({outputStyle: 'compressed'}).on('error', sass.logError))

如 gulp-sass 选项. 您之前的错误可能是由于不将您的选项包含在 {} 大括号中(它是一个对象).

as in gulp-sass options. Your earlier error was probably due to not including your options in {} braces (it is an object).

:

你的另一个错误是一样的

And your other error is the same

.pipe(autoprefixer(browsers: ['last 2 versions', '> 5%', 'Firefox ESR']))

应该是

.pipe(autoprefixer( { browsers: ['last 2 versions', '> 5%', 'Firefox ESR'] } ))

注意花括号.通常 gulp 插件的选项是 objects，因此它们需要用大括号 {} 包裹起来.

Note the curly braces. Usually the options to gulp plugins are objects so they need to be wrapped in braces {}.
