角度生成错误:TypeError:无法读取未定义的属性"line" [英] angular build error: TypeError: Cannot read property 'line' of undefined

问题描述

我突然遇到生产失败的错误. 我正在运行以下命令:

I am suddenly facing build fail error for production. I am running this command:

ng build --prod

并出现以下错误:

D:\a\1\s\node_modules\clean-css\lib\reader\input-source-map-

tracker.js:37
  if (originalPosition.line === null && line > 1 && selectorFallbacks > 0) {
                      ^

前几天它曾经可以正常工作，但突然停止工作. 有谁知道为什么会这样?

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

(我正在使用angular cli版本1.6.7)

(I am using angular cli version 1.6.7)

预先感谢

推荐答案

好的！已确认这是在最新版本的cli中发生的.

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

我最终通过将版本降低到1.6.7并删除了^来解决了我的问题 我什至在降低版本后也遇到了这个问题:

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

"@ angular/cli":"^ 1.6.7"

"@angular/cli": "^1.6.7"

然后我删除了^以修复cli版本，现在它可以正常工作了.

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

我要求角度小组解决此角度cli问题，以便我们可以使用最新版本.

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

我希望这会有所帮助.
