Error while running gulp html:build?

Question

gulp.js

created a package.json document

{
  "name": "habr",
  "version": "1.0.0",
  "description": "",
  "author": "",
  "license": "ISC",
  "dependencies": {
    "gulp": "^3.8.11"
  },
  "devDependencies": {
    "gulp-load-plugins": "^1.2.0",
    "gulp-rigger": "^0.5.8"
  }
}

Created gulpfile.js

'use strict';

var gulp = require('gulp'),    
    rigger = require('gulp-rigger');
   


var path = {
    build: { //Тут мы укажем куда складывать готовые после сборки файлы
        html: 'build/',
        js: 'build/js/',
        css: 'build/css/',
        img: 'build/img/',
        fonts: 'build/fonts/'
    },
    src: { //Пути откуда брать исходники
        html: 'src/*.html', //Синтаксис src/*.html говорит gulp что мы хотим взять все файлы с расширением .html
        js: 'src/js/main.js',//В стилях и скриптах нам понадобятся только main файлы
        style: 'src/style/main.scss',
        img: 'src/img/**/*.*', //Синтаксис img/**/*.* означает - взять все файлы всех расширений из папки и из вложенных каталогов
        fonts: 'src/fonts/**/*.*'
    },
    watch: { //Тут мы укажем, за изменением каких файлов мы хотим наблюдать
        html: 'src/**/*.html',
        js: 'src/js/**/*.js',
        style: 'src/style/**/*.scss',
        img: 'src/img/**/*.*',
        fonts: 'src/fonts/**/*.*'
    },
    clean: './build'
};

gulp.task('html:build', function () {
    gulp.src(path.src.html) //Выберем файлы по нужному пути
        .pipe(rigger()) //Прогоним через rigger
        .pipe(gulp.dest(path.build.html)) //Выплюнем их в папку build
        .pipe(reload({stream: true})); //И перезагрузим наш сервер для обновлений
});

gulp html:build on the command line throws the following error

folder path/gulp test$ gulp html:build
Command 'gulp' not found, did you mean:
Command 'gslp' from package 'ghostscript' (main)
gulp: command not found

Answer 1

either install galp globally
or run galp via npm scripts

{
  "scripts": {
    "build": "gulp html:build"
  }
}

Answer 2

At the moment, another error with what can be connected?

Answer 3

Either you didn't post the whole gulp.js. Either the indication in the header file var = plugin to reload is missing. Because you use it
But not connected. Set up the gulp-browsersync plugin and update the line to match

Answer 4

Absolutely the same problem.
I have Ubuntu 14.0
SOLUTION that worked for me: add path to node_modules/.bin folder to system PATH variable:

export PATH=$PATH:.node_modules/.bin:../node_modules/.bin
