ReferenceError：t没有定义
我有我的express.js / blade.js模板使用i18next库这个代码index.coffee

我得到的错误是当我加载网站是：

我的错误出现在t("ns.layout:menu."+i)我正在初始化i18next，但无法看到为什么在此index.coffee它不工作！
任何意见非常赞赏
这不是因为i18next，你的代码中缺lesst。 当你这样做
- var foo = 'bar' = foo h1= foo
你得到
bar<h1>bar</h1>
所以
a(href=""+i class=""+i data-i18n="menu."+i)!=t("ns.layout:menu."+i)
翻译成
a<href=""+i class=""+i data-i18n="menu."+i> ##Content from t##</a>
但是t没有在你的header.blade中定义。 所以它显示错误。
似乎命令没有正确设置，就好像我把它app.use i18n.handle后面，然后i18nxt函数就可以用于快速应用了。
app.use (req, res, next) -> #the status option, or res.statusCode = 404 #are equivalent, however with the option we #get the "status" local available as well res.render '404', status: 404, url: req.url
