Обновить версию bem-xjst?

@kompolom, вот пример конфига, обрати внимание на секцию templateEngine и scripts.

specs.configure({
        destPath: 'desktop.specs',
        levels: ['common.blocks'],
        sourceLevels: levels.concat('libs/bem-pr/spec.blocks'),
        jsSuffixes: ['vanilla.js', 'browser.js', 'js'],
        depsTech: require('enb-bem-techs').deps,
        langs: true,
        scripts: ['https://yastatic.net/es5-shims/0.0.2/es5-shims.min.js'],
        templateEngine: {
            templateTech: require('enb-bemxjst/techs/bemhtml'),
            templateOptions: { sourceSuffixes: ['bemhtml', 'bemhtml.js'] },
            htmlTech: require('enb-bemxjst/techs/bemjson-to-html'),
            htmlTechOptionNames: { bemjsonFile: 'bemjsonFile', templateFile: 'bemhtmlFile' }
        }

Что-то не пойму. Такая же проблема возникает при обновлении на bem-components@v5 и bem-core@v4. Пробовал в сборку добавить

        scripts: ['https://yastatic.net/es5-shims/0.0.2/es5-shims.min.js'],
        templateEngine: {
            templateTech: require('enb-bemxjst/techs/bemhtml'),
            templateOptions: { sourceSuffixes: ['bemhtml', 'bemhtml.js'] },
            htmlTech: require('enb-bemxjst/techs/bemjson-to-html'),
            htmlTechOptionNames: { bemjsonFile: 'bemjsonFile', templateFile: 'bemhtmlFile' }
        }

таже ошибка...

необходимо добавить engineOptions : { elemJsInstances : true }, т.к. начиная с bem-core v4 появилась поддержка JS у элементов.

@tadatuta сейчас такой конфиг

    config.module('enb-bem-specs').createConfigurator('specs').configure({
        destPath       : 'common.specs',
        levels         : [].concat(project),
        sourceLevels   : [].concat(specs, libs, project),
        jsSuffixes     : ['vanilla.js', 'browser.js', 'js'],
        depsTech       : techs.bem.depsOld,
        scripts        : ['https://yastatic.net/es5-shims/0.0.2/es5-shims.min.js'],
        templateEngine : {
            bemtreeTemplateTech : require('enb-bemxjst/techs/bemtree'),
            templateTech        : require('enb-bemxjst/techs/bemhtml'),
            templateOptions : {
                sourceSuffixes : ['bemhtml', 'bemhtml.js'],
                engineOptions  : { elemJsInstances : true }
            },
            htmlTech : require('enb-bemxjst/techs/bemjson-to-html'),
            htmlTechOptionNames : { bemjsonFile : 'bemjsonFile', templateFile : 'bemhtmlFile' }
        }
    });

выпадает ошибка

Убрал sourceSuffixes : ['bemhtml', 'bemhtml.js'], собралось. Но теперь другая проблема Failed to start mocha: Init timeout на всех тестах

@belozyorcev правильный конфиг для bem-core v4 можно посмотреть в https://github.com/bem/bem-components/commit/f427fc39fb8e3ad4cc56e417c794f3d1d4dcb3fd Он совершенно точно работает.

@tadatuta вроде завелоь.

Сейчас правда борюсь с Error: Module "spec": can't resolve dependence "i-bem-dom"

вроде что-то нашёл https://github.com/bem/bem-components/issues/1565
