Question

我正在尝试在Vue项目中更改iView的主题。我按照此链接中找到的步骤进行操作：

https://www.iviewui.com/docs/guide/theme-en

我在主项目文件夹中创建了一个名为my-theme的文件夹。在其中，我有一个名为index.less的文件，其中包含主题的样式。我还使用以下命令安装了less-loader

npm install less-loader --save-dev

然后，我将主题导入到main.js文件中，如下所示：

import iView from 'iview';
import '../my-theme/index.less';

Vue.use(iView);

但是，当我尝试加载项目时，出现以下错误：

Failed to compile.

如何解决此问题？感谢您的帮助。

更新

我还使用less安装了npm install less --save。现在，我收到此错误：

Failed to compile.

./my-theme/index.less (./node_modules/css-loader??ref--10-oneOf-3-1!./node_modules/postcss-loader/src??ref--10-oneOf-3-2!./node_modules/less-loader/dist/cjs.js??ref--10-oneOf-3-3!./my-theme/index.less)

您需要在vue.config.js中启用javascript loaderOptions

如果项目的根文件夹中没有 vue.config.js 文件，请创建该文件并粘贴以下代码：

module.exports = {
    css: {
        loaderOptions: {
            less: {
                javascriptEnabled: true
            }
        }
    }
};

否则，您只需将此代码放入 vue.config.js 文件中。您的文件现在看起来像这样：

module.exports = {
    ...// other options
    ...
    css: {
        loaderOptions: {
            less: {
                javascriptEnabled: true
            }
        }
    }
    ...
    ...
};

尝试使用iView在Vue项目中使用主题时无法编译错误
