我是 ember 新手，无法找到此错误背后的原因。 Ember 无法生成 CSS 文件。

我尝试通过 bower install 手动添加 ember-cli-shims 和引导程序，但问题仍然没有得到解决。

【问题讨论】：

标签： css twitter-bootstrap ember.js

【解决方案1】：

ember-cli-preprocessor-registry 3.1.0 (details) 中有一些回归。 3.1.1 已经发布，现在一切正常。您可能需要删除 node_modules 目录并运行 npm install 以更新依赖项。

【讨论】：

您能否告知如何检查 ember-cli-preprocessor-registry 版本？
node_modules/ember-cli-preprocess-registry/package.json：寻找“版本”属性。
谢谢@chekmare，我已经检查了 ember-cli-preprocessor-registry 版本，它被提到为"raw": "ember-cli-preprocess-registry@^3.0.0" 你能否告知如何升级 ember-cli-preprocessor-registry 版本。供大家参考，我系统当前的ember版本是：ember-cli: 2.10.0 node: 6.10.0 os: win32 x64 npm: 3.10.10
"raw" 并不是真正的版本，但无论如何您不必做任何特别的事情。只需删除 node_modules 目录并运行“npm install”。
我已经尝试过了，并将 mvn clean install 安装到包含 ember build 的完整项目中；但是没有创建css文件。但是没有出现错误消息。

【解决方案2】：

我试过了，发现生成的cmt css文件（dist/assets/cmt.css）是0字节。
