未明错误:模板是用较旧版本的车把预编译的。

Question

我使用Bower来管理我的前端依赖项，使用grunt-ember-templates来预编译工具栏模板。

这些是bower.json中的依赖项

"devDependencies": {
  "ember": "~1.3.1",
  "jquery": "~2.0.3",
  "normalize-css": "~2.1.3",
  "jquery.cookie": "~1.4.0",
  "font-awesome": "~4.0.3"
}

..。在package.json中

"devDependencies": {
  "bower": "~1.2.8",
  "grunt": "~0.4.2",
  "grunt-contrib-copy": "~0.5.0",
  "grunt-contrib-clean": "~0.5.0",
  "grunt-contrib-concat": "~0.3.0",
  "handlebars": "~1.3.0",
  "ember-template-compiler": "~1.4.0-beta.1",
  "grunt-ember-templates": "~0.4.18"
},

但是，当我编译和运行我的Ember应用程序时，我会得到以下错误：

Assertion failed: Ember Handlebars requires Handlebars version 1.0 or 1.1, COMPILER_REVISION expected: 4, got: 5 - Please note: Builds of master may have other COMPILER_REVISION values.

Uncaught Error: Template was precompiled with an older version of Handlebars than the current runtime. Please update your precompiler to a newer version (>= 2.0.0) or downgrade your runtime to an older version (<= 1.0.rc.2).

以下是这些版本：

> Ember.VERSION
> "1.3.2"
> Handlebars.VERSION
> "v2.0.0-alpha.1"

正如您所看到的，handlebars不是显式地作为一个依赖项来提到的，而是通过Ember解析的。但不知何故，它解决了一个更新(不兼容)的版本。

如何修复handlebars的版本

Answer 1

做bower install handlebars#1.3.0 --save，但是是的，这是保尔的一个问题。我看到你创造了https://github.com/bower/bower/issues/1114
