It used to work fine a few days ago but suddenly stopped working. Does any body have idea that why is this happening?

几天前它还可以正常工作，但突然就不工作了。有没有人知道为什么会这样?

(I am using angular cli version 1.6.7)

Alright! It's confirmed that this is happening in latest version of angular cli.

好吧!这在最新版本的角cli中得到了证实。

I finally fixed my issue by lowering version to 1.6.7 and by removing ^ I was facing this issue even after lowering version:

我终于固定我的问题通过降低版本1.6.7和通过消除^我面临这个问题即使降低版本:

"@angular/cli": "^1.6.7"

:“@angular / cli ^ 1.6.7”

Then I removed ^ to fix the cli version and now it works fine.

然后我删除^修复cli版本和现在工作正常。

I request angular team that please fix this angular cli issue so that we can use latest versions.

我请求角团队，请修复这个角cli问题，以便我们可以使用最新版本。

I hope this would help.

我希望这能有所帮助。

While it seems clean-css is failing fantastically after @angular/cli 1.6.7, this issue can be resolved for later versions of @angular/cli, regardless.

尽管在@棱角/cli 1.6.7之后，看起来清晰的css在不可思议地失败了，但是这个问题可以在以后的@棱角/cli版本中得到解决，无论如何。

I got a lead on this issue being caused by non-breaking spaces: https://github.com/jakubpawlowicz/clean-css/issues/1006

在这个问题上，我得到了一个线索:https://github.com/jakubpawlowicz/css/es/1006。

I was then able to resolve the issue by opening the src/ folder as a workspace in Notepad++, filtering on *.scss and *.css, and doing a search with Regex on using \xA0 to find non-breaking spaces in the scss/css files; I found one. Once removed, my error went away.

然后我就可以通过在Notepad++中打开src/文件夹作为工作区来解决这个问题，在*上进行过滤。scss和*。使用Regex使用\xA0搜索scss/css文件中的非中断空间;我发现一个。一旦被删除，我的错误就消失了。
