node.js - Angular 项目中的 Webpack 错误

Question

将我的全局 Angular CLI 升级到版本 1.7.3 后出现此错误(不确定是否完全破坏了构建)。 Web pack 似乎不再理解路径引用。

ERROR in ./src/app/app.component.css
(Emitted value instead of an instance of Error) CssSyntaxError: C:\Users\kkehinde\Documents\WebStorm\Admin\src\assets\css\theme-default.css:7102:19: Can't resolve '../img/filetree/code.png'

  7103 | }
  7104 | li.ext_zip {

       |                   ^
  7106 | }
  7107 | /* END Filetree */

我的 Package.json 在下面，我将锁定的 node-sass 添加到版本 4.7.2，因为有人建议这是破坏 webpack 构建的原因，但仍然会出现上述错误。

将 URL 作为字符串传递。 这样:

li.ext_xml {

7102 | background: url("../img/filetree/code.png") left top no-repeat; | ^ 7103 | }
