这个错误是由于在编译Element UI的CSS文件时发生的。可能是因为你的PostCSS版本过低，需要更新到最新的版本。你可以尝试执行以下命令来更新PostCSS：

npm install postcss-loader postcss-import postcss-url --save-dev

如果还有问题，请尝试更新CSS Loader：

npm install css-loader --save-dev

如果仍然出现问题，请尝试清除npm缓存并重新安装Element UI：

npm cache clean --force
npm install element-ui --save
