gulp + browser-sync Cannot GET / error

问题

I am learning the front-end build system currently gulp, i want to use brower-sync and the problem is it is not throwing an error in the commad line but instead when it brings up the browser it will not display my html file and it will say "Cannot GET /" error in the browser window. This is my gulpfile.js code

var gulp = require('gulp'),
   uglify = require('gulp-uglify'),
   compass= require('gulp-compass'),
   plumber = require('gulp-plumber'),
   autoprefixer = require('gulp-autoprefixer'),
   browserSync = require('browser-sync'),
   reload = browserSync.reload,
   rename = require('gulp-rename');


gulp.task('scripts', function() {
   gulp.src(['public/src/js/**/*.js', '!public/src/js/**/*.min.js'])
      .pipe(plumber())
      .pipe(rename({suffix: '.min'}))
      .pipe(uglify())
      .pipe(gulp.dest('public/src/js/'));
});

gulp.task('styles', function() {
   gulp.src('public/src/scss/main.scss')
      .pipe(plumber())
      .pipe(compass({
          config_file: './config.rb',
          css: './public/src/css/',
          sass: './public/src/scss/'
      }))
     .pipe(autoprefixer('last 2 versions'))
     .pipe(gulp.dest('public/src/css/'))
     .pipe(reload({stream:true}));
});


gulp.task('html', function() {
  gulp.src('public/**/*.html');
});  

gulp.task('browser-sync', function() {
    browserSync({
      server: {
         baseDir: "./public/"
      }
   });
});

gulp.task('watch', function() {
   gulp.watch('public/src/js/**/*.js', ['scripts']);
   gulp.watch('public/src/scss/**/*.scss', ['styles']);
   gulp.watch('public/**/*.html', ['html']);
});

gulp.task('default', ['scripts', 'styles', 'html', 'browser-sync', 'watch']);

i am using windows and git bash and version is "browser-sync": "^2.12.5" so what is the problem and try to explain for me in order to get something out of it.

回答1:

Is there an index.html file in your ./public/ folder? If not, you need to tell browserSync what is your start page. You can also get browserSync to show the listing of the base directory, see update below.

You could also try to use public without the leading dot.

Edit: The startPath config directive does not seem to work, use index instead

...
gulp.task('browser-sync', function() {
   browserSync({
     server: {
        baseDir: "public/",
        index: "my-start-page.html"
     }
   });
});
...

Update: Actually you can get directory listing with browserSync. That way it would show a list of files in public, not the Cannot Get error

...
gulp.task('browser-sync', function() {
   browserSync({
     server: {
        baseDir: "public/",
        directory: true
     }
   });
});
...

I got this to work when the index.html file was inside the same folder:

    browserSync.init({
        server: {
            baseDir: "./"
        }
    });

回答3:

gulp.task('browser-sync', function() {
    browserSync({

      server: {
            baseDir: "./"
            },

            port: 8080,
            open: true,
            notify: false
    });
});

I solved my "Cannot GET" errors in browser-sync by always pointing to a .html file in code, or by having a folder structure ending with and index.html

<a href="/about">About</a> <!-- Cannot GET error-->
<a href="/about">About</a> <!-- same code as above, but works if your site structure is:  ./about/index.html-->
<a href="/about.html">About</a> <!-- OK -->

My Gulp file for reference (using browser-sync with jekyll, so everything is in the ./_site folder, and the gulpfile is in ./)

var gulp = require('gulp');
var shell = require('gulp-shell');
var browserSync = require('browser-sync').create();

gulp.task('build', shell.task(['jekyll build --watch']));

// serving blog with Browsersync
gulp.task('serve', function () {
    browserSync.init(
        {
            server: {baseDir: '_site/'}
        }
    );

    // Reloads page when some of the already built files changed:
    gulp.watch('_site/**/*.*').on('change', browserSync.reload);
});

gulp.task('default', ['build', 'serve']);

Hope it helps.

May be you have not index.html in baseDir: '_site/'? In order to see your static web-page in the web-browser instead of that annoying message you have to rename a file your_file.html to index.html. This will solve Cannot GET/ problem.

回答6:

gulp.task('serve',['sass'], function() {
    bs.init({
        server: "./app",
        startPath: "/index.html", // After it browser running
        browser: 'chrome',
        host: 'localhost',
        port: 4000,
        open: true,
        tunnel: true
    });

回答7:

In my case, this helped me:

server: {
            baseDir: '.',
            index: "index.html"
        }

回答8:

gulp.task('server', function()
{
        browserSync.init(["public/src/css/","public/src/js"],{ 
            server: "./",
            startPath: "./index.html", // After it browser running
            //    browser: 'chrome',
            host: 'localhost',
            //       port: 4000,
            open: true,
            tunnel: true    }); 
});

gulp.task('default', ['scripts', 'styles', 'html', 'server', 'watch']);
