【问题描述】：

我试图在我的表面上运行一个反应项目作为开发服务器，如果给我下面和标题中显示的错误。当我在我的电脑上运行相同的配置时，我没有遇到这个问题。（我尝试创建相同的条件，但它不起作用）。

错误：

【问题讨论】：

标签： node.js reactjs npm node-sass resolve-url-loader

【解决方案1】：

我遇到了同样的错误。为了解决这个问题，我不得不导航到

node_modules/resolve-url-loader

打开

index.js

在var options 下将removeCR 从“false”更改为“true”。

【讨论】：

谢谢，刚刚遇到同样的问题，这对我有用。
我相信是的，你可以在你的 webpack.config.js 文件中添加如下规则来启用 removeCR。 loader: 'resolve-url-loader', options: { removeCR: true },
这对于本地开发可能已经足够了，但对于生产（或根本）来说这是不可接受的。 package.json 将自动创建 node_modules 目录并从其源代码安装模块，因此除非您分叉 repo 并进行此更改，否则我不建议直接更改模块文件。
谢谢，这也解决了我的错误Error: resolve-url-loader: CSS error Cannot read property 'toString' of undefined
可以通过在 scss 文件中将 url(..) 更改为新的 URL(...) 来解决这个问题。 Webpack 5 需要新的 URL(...) 声明

【解决方案2】：

另一种选择是为行尾序列类型配置 IDE 或编辑器，从 CRLF 更改为 LF ...它们只是替代品...尝试一下。

【讨论】：

【解决方案3】：

嗯，解决方案必须与某些包配置或其他东西有关。但我想分享我应用的解决方案：

@import "variables";
@import "colored-balls";
@import "glowing-ball";
@import "pixel-loader";
@import "square-box";
@import "circle-loader";
@import "jumping-dots-loader";

查找负责模块无法解析的文件（查找错误文件）。使用 ctrl + click ... 并逐条评论，直到您看到哪些您没有阅读，当您找到它们时：您可以对它们评论，或者删除它们。它们是预加载器，我不需要它们。

/* @import "彩色球"; */

/* @import "像素加载器"; */

【讨论】：

【解决方案4】：

使用 :

签出 git repo

[core]
    autocrlf = false

因为 resolve-url-loader 不支持 Windows CRLF，所以使用 node-sass 但选项不可用于使用 Create-React-App 进行设置。见https://github.com/sass/node-sass/issues/2756
