我已经成功使用 Zurb Foundation for Emails 有一段时间了。突然，构建过程失败了。
我更新到 Node 7.7.2 和 NPM 4.1.2，删除了 node_modules 目录并运行npm install重新安装依赖项，但它并没有解决问题。
$ npm run build
foundation-emails-template@1.0.0 build /Users/[REDACTED]
gulp --production

或者，如果我尝试自己运行gulp --production：
$ gulp --production

[12:29:39] Using gulpfile ~/[REDACTED]/gulpfile.babel.js
/usr/local/lib/node_modules/gulp/bin/gulp.js:129
gulpInst.start.apply(gulpInst, toRun);
^

npm start按预期工作；我只是无法内联样式。
有任何想法吗？TIA。
