最近几天我研究meteor js框架，我想为meteor编写一个包，但是当我尝试一个包时，我有一个关于模板的问题
在我的package.js
中 api.use([
'templating',
"coffeescript",
], "client");
api.addFiles([
'client/breadcrumb.coffee',
'client/helpers.coffee',
'client/views/breadcrumb/crumb.html'
], 'client');
api.use(['coffeescript'], 'server');
api.addFiles('server/breadcrumb.coffee', 'server');
在我的helper.coffee中我使用这样的代码片段：
Template.breadcrumbs.helpers ->
crumbs: () ->
Breadcrumb.getCrumbs()
当我在我的应用程序中包含我的软件包时，它无效。 这是错误：
Uncaught ReferenceError: Template is not defined helpers.coffee:1

答案 0 :(得分：2)
这只是一个加载顺序问题：Meteor要求必须在Spacebars中声明模板，然后才能引用它以在JS中定义其助手。
通过在源文件列表中声明您希望在JS对应项之前加载Spacebars HTML，您的错误应该消失。
api.addFiles([
'client/views/breadcrumb/crumb.html',
'client/helpers.coffee',
'client/breadcrumb.coffee'
], 'client');
