努力在没有 web-pack 的现有 React 项目中安装 SCSS

Question

我继承了一个在 JS 中使用 CSS 的 React 应用程序。这很麻烦，因为所有的 SCSS 都是以字符串形式编写的，因此很难使用，因为无法通过 IDE 进行代码提示或格式化。

我习惯于使用 web-pack 处理这类事情，但我认为它不是解决方案的一部分，因为我在 package.json 文件中找不到对它的引用。

我正在尝试切换到 SCSS，但不是很管理。我正在使用以下声称可以在没有 web-pack 的情况下工作的教程：

这是我的 package.json 的副本：

}

当我使用 npm startr 命令运行应用程序时，我收到以下错误：

> accelerator@0.1.0 startr D:\Projects\iLab\Code\Product_dashboard_Web\accelerator
> npm-run-all — parallel start watch:sass

ERROR: Task not found: "—", parallel"
npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! accelerator@0.1.0 startr: `npm-run-all — parallel start watch:sass`
npm ERR! Exit status 1
npm ERR!
npm ERR! Failed at the accelerator@0.1.0 startr script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

我不确定是否存在一些我没有看到的依赖项或版本问题，或者还有什么问题。

如果有人对我提出任何建议，我将不胜感激

Answer 1

您的startr 命令错误，

npm-run-all — parallel start watch:sass

应该是，

npm-run-all --parallel start watch:sass

Answer 2

您的项目正在使用来自create-react-app 的react-scripts。 CRA 使用 webpack 并且与 SASS 配合得很好。

如果你想更改默认的 webpack 配置，你需要eject（不推荐）或使用react-app-rewired（或类似工具）之类的东西。
