有人可以建议我做错了什么吗?

Can someone kindly advise what I am doing incorrectly?

推荐答案

出现此问题的原因是iron-router@1.0.0-pre-x(例如1.0的Beta)与当前使用的0.9.x版本之间存在差异铁路由器.

The reason you have this issue is there is a discrepancy between the iron-router@1.0.0-pre-x (like a Beta for 1.0) and the currently in use 0.9.x version of iron router.

用于为模板route定义http://localhost:3000/route的路由的旧表示法如下:

The old notation for defining a route for http://localhost:3000/route, for the template route would be as follows:

Router.route("route", { path : '/' });

但是在新版本中，当前在github上的devel上(我认为示例基于以下内容):

However in the new version, which is currently on github on devel (which I presume the examples are based on is as follows):

Router.route("/", function() {
    this.render("route");
});

问题是使用底部的符号会导致错误Couldn't find a template named "/"，因为Route.route的第一个参数现在是路径而不是模板.

The problem is using the notation on the bottom would lead to the error Couldn't find a template named "/" since the first param of the Route.route is now a path instead of a template.

解决此问题的方法是使用铁路由器的预发行版本(版本字符串可在github上的package.js文件中找到):

The way to fix this is to either use the pre-release version of iron router (the version string can be found in the package.js file on github):

meteor remove iron:router
meteor add iron:router@1.0.0-pre3

或者通过查看与github上的发行版捆绑在一起的示例而不是像这样的devel分支来使用旧的表示法:

Or to use the old notation by looking at an example bundled with a release on github instead of the devel branch like this one: https://github.com/EventedMind/iron-router/tree/v0.9.2-rc0
