Why doesn't Gulp compile slim?

Question

css

There is a project made on scss, slim and all this on middleman (static site generator in ruby) - i.e. cut tools.
Because I don't know Ruby, so I decided to use Gulp instead of Middleman.
Set up tasks

'use strict';

var gulp = require('gulp'),
    watch = require('gulp-watch'),
    prefixer = require('gulp-autoprefixer'),
    uglify = require('gulp-uglify'),
    sass = require('gulp-sass'),
    slim = require('gulp-slim'),
    cssmin = require('gulp-minify-css'),
    imagemin = require('gulp-imagemin'),
    pngquant = require('imagemin-pngquant'),
    rimraf = require('rimraf'),
    browserSync = require("browser-sync"),
    reload = browserSync.reload;

var path = {
    build: {
        html: 'build/views/',
        js: 'build/assets/javascripts/',
        css: 'build/assets/stylesheets/',
        img: 'build/assets/images/',
        fonts: 'build/assets/fonts/'
    },
    src: {
        html: 'app/views/**/*.slim',
        js: 'app/assets/javascripts/application.js',
        style: 'app/assets/stylesheets/**/*.scss',
        img: 'app/assets/images/**/*.*',
        fonts: 'app/assets/fonts/*.*'
    },
    watch: {
        html: 'app/views/**/*.slim',
        js: 'app/assets/javascripts/**/*.js',
        style: 'app/assets/stylesheets/**/*.scss',
        img: 'app/assets/images/**/*.*',
        fonts: 'app/assets/fonts/*.*'
    },
    clean: 'build'
};

var config = {
    server: {
        baseDir: "./build"
    },
    tunnel: true,
    host: 'localhost',
    port: 9000,
    logPrefix: "Frontend_Devil"
};

gulp.task('webserver', function () {
    browserSync(config);
});

gulp.task('clean', function (cb) {
    rimraf(path.clean, cb);
});

gulp.task('html:build', function () {
    gulp.src(path.src.html) 
        .pipe(slim({
            pretty: true
        }))
        .pipe(gulp.dest(path.build.html))
        .pipe(reload({stream: true}));
});

gulp.task('js:build', function () {
    gulp.src(path.src.js) 
        
        .pipe(uglify()) 
        .pipe(gulp.dest(path.build.js))
        .pipe(reload({stream: true}));
});

gulp.task('style:build', function () {
    gulp.src(path.src.style) 

        .pipe(sass({
            includePaths: ['app/assets/stylesheets/'],
            outputStyle: 'compressed',
            errLogToConsole: true
        }))
        .pipe(prefixer())
        .pipe(cssmin())
        .pipe(gulp.dest(path.build.css))
        .pipe(reload({stream: true}));
});

gulp.task('image:build', function () {
    gulp.src(path.src.img) 
        .pipe(imagemin({
            progressive: true,
            svgoPlugins: [{removeViewBox: false}],
            use: [pngquant()],
            interlaced: true
        }))
        .pipe(gulp.dest(path.build.img))
        .pipe(reload({stream: true}));
});

gulp.task('fonts:build', function() {
    gulp.src(path.src.fonts)
        .pipe(gulp.dest(path.build.fonts))
});

gulp.task('build', [
    'html:build',
    'js:build',
    'style:build',
    'fonts:build',
    'image:build'
]);


gulp.task('watch', function(){
    watch([path.watch.html], function(event, cb) {
        gulp.start('html:build');
    });
    watch([path.watch.style], function(event, cb) {
        gulp.start('style:build');
    });
    watch([path.watch.js], function(event, cb) {
        gulp.start('js:build');
    });
    watch([path.watch.img], function(event, cb) {
        gulp.start('image:build');
    });
    watch([path.watch.fonts], function(event, cb) {
        gulp.start('fonts:build');
    });
});


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

But on the slim it gives an error
If you delete that line, then plug in the next one:
javascript_include_tag
If you delete it, then this file compiles (although the Cyrillic alphabet turns to krakozyabr), but finds an error in another file.
Maybe there are suggestions - what is the reason?

Answer 1

In defs, define the gradient https://developer.mozilla.org/en/docs/Web/SVG/%D0%... and in the stroke of the circle, instead of the color, write
stroke: url(#gradient-name)
for your example

Answer 2

Go link to what is implemented

Answer 3

stylesheet_link_tag is a middleman helper method. Gulp, of course, is not aware of it.
Are you by any chance trying to solve the problem with the square-nest method?

Answer 4

I had a similar problem, slim didn't compile, unfortunately the error text was not saved, but the error was also in events.js only on a different line and started in the same way throw err: //Unhandled 'error' event, and the error text was from artifacts . The problem was that ruby ​​didn't write the path to the windows environment variables. Although the corresponding checkbox was marked in the installer.
Added manually, rebooted the system, and it worked.
