Question

我正在运行我的Angular应用程序，为本地开发人员提供grunt服务，如果我检查一个元素并尝试使用Chrome开发工具调整浏览器中的样式，一切都变得非常迟钝和无法使用。我试图研究这个问题，但我找不到任何有用的东西。有人有什么想法吗？

编辑：我使用generator-angular-ui-router来生成我的项目，并且可能有些东西在我的Gruntfile中搞砸了，因为我不相信在使用grunt之前我遇到过这个问题。

响应我的Gruntfile请求，这里是：

我认为主要问题来自gem Compass，因为每次进行更改时她都很慢编译SASS，所以你可以尝试更新gem Compass。

gem update compass

你可以展示你的指南针吗？请给我红宝石版。

gem list compass

ruby -v

Grunt LiveReload is really slow

由于我不知道您的CSS是如何传送到Chrome浏览器的。

如果只是关于在Chrome中进行编辑，那么它可能来自Chrome中的设置吗？

或尝试使用Chrome Canary或Firefox Developer版本：

https://www.google.fr/chrome/browser/canary.html

https://www.mozilla.org/fr/firefox/developer/

您编译的CSS有多少行？
