Question

当我更改HTML和CSS中的代码时，它会响应：

[BS]重新加载浏览器...... [15:34:19]完成＆＃39; browserSync＆＃39;在1.46毫秒之后 / c / Users / weiyinpeng / AppData / Roaming / npm / gulp：第14行：8084分段故障节点＆＃34; $ basedir / node_modules / gulp / bin / gulp.js＆＃34; ＆＃34; $ @＆＃34;

这是我的gulpfile.js代码。

    let sourcemaps = require("gulp-sourcemaps");
    let babel = require("gulp-babel")
    let concat = require("gulp-concat")
    let rename = require("gulp-rename")
    let md5 = require("gulp-md5")
    let uglify = require("gulp-uglify")
    let pump = require("pump")
    let del = require("del")
    // Css process.
    gulp.task("PC-postcss", ()=>{
        var processors = [
            postcssMixins,

            autoprefixer({

我已经检查了我的代码几天，并发现它有什么问题。 PC-postcss中的任务应改为：

gulp.task("PC-postcss", ()=>{
    var processors = [
        postcssMixins,
        postcssSimpleVars,
        postcssNested,
        autoprefixer({ 
            browsers: ['last 2 version', 'safari > 5', 'ff > 31', 'opera 12.1', 'IOS 6', 'IE 8', 'Android 4','> 1%'] 
        })];

    return gulp.src(["./today-pc/static/css/*.scss"])
        .pipe(postcss(processors))
        .pipe(rename({
            extname:".css"
        })) 
        .pipe(gulp.dest("./today-pc/static/css/"))
         // .pipe(browserSync.stream());

});

gulp.src中的路径是错误的。在gulp的Path分析中，路径中必定出错。谢谢你们。我第一次使用stackoverflow，我很抱歉我曾经做过的。

当我使用gulp和browser-sync时，它犯了一个错误
