Question

我正在开发一个简单的NextJS应用程序，但是在使用SASS / SCSS进行组件级样式设计时遇到了麻烦。当用户第一次登陆页面时，一切看起来都很好，但是当用户导航到页面/about或从/about到/时，组件样式没有得到渲染，用户需要刷新页面才能查看样式?

import './Layout.scss';

class Layout extends React.PureComponent {

Answer 1

这是我解决问题的方法。 ?

随着Next.js 9.3的发布，不再需要@zeit/next-sass和@zeit/next-css。 ?
我还执行以下操作：

将styled-jsx-plugin-sass node-sassa添加为dev-dep
创建一个.babelrc文件并添加以下内容：

{
  "presets": [
    [
      "next/babel",
      {
        "styled-jsx": {
          "plugins": ["styled-jsx-plugin-sass"]
        }
      }
    ]
  ]
}

所以我有两种选择：

在<style jsx>上添加我的sass / scss
将我的组件sass / scss文件重命名为<ComponentName>.module.scss

第二个选择是A的麻烦，您需要import styles from './ComponentName.module.scss并将元素类添加为className={styles.ComponentName}或className={styles['ComponentName-button']}。 ?
