为什么在尝试将Angular项目从基于CSS的项目转换为SCSS的项目时出现此错误？

问题描述

我在尝试将使用CSS的Angular项目转换为使用SCSS SASS的项目时遇到了一些问题。

我正在关注本教程：https://medium.com/@ngubanethabo.ambrose/migrate-from-css-to-scss-stylesheets-for-existing-angular-application-d61f8061f5b7

所以我执行了以下命令：

ng config schematics.@schematics/angular:component.styleext scss

现在进入我的 angular.json 文件，我具有正确的值：

“示意图”：{ “ @ schematics / angular：component”：{ “ styleext”：“ scss” }

然后，我尝试按照说明使用重命名器工具，但是没有用。我执行了：

sudo renamer -d --path-element ext --find css -replace scss *

获得此错误：

developer@developer-virtual-machine:~/Documents/Angular-WS/color_patch/src$ sudo renamer -d --path-element ext --find css -replace scss *
Singular option already set [path-element=ext]

所以我尝试手动执行此操作：

将Bootstrap CSS文件重命名为SCSS（我不确定这是正确的）：
将单个组件的CSS文件重命名为SCSS

问题是，现在执行 ng服务时，我收到以下错误消息：

为什么？怎么了？我想念什么？如何正确将其转换为SCSS项目？

解决方法

尝试更新此部分：

"styles": [
          "src/styles.css"
        ],

对此：

"styles": [
          "src/styles.scss"
        ],

编辑：

尝试删除第一个："schematics": {}, 并检查您的@imports

编辑2：

更改此项：

           "styles": [
          "node_modules/bootstrap/dist/css/bootstrap.scss","./node_modules/primeicons/primeicons.scss","./node_modules/primeng/resources/themes/nova-light/theme.scss","./node_modules/primeng/resources/primeng.min.scss","node_modules/@fullcalendar/core/main.min.scss","node_modules/@fullcalendar/daygrid/main.min.scss","node_modules/@fullcalendar/timegrid/main.min.scss","./node_modules/font-awesome/css/font-awesome.scss","src/styles.scss"
        ],

对此：

           "styles": [
          "../node_modules/bootstrap/dist/css/bootstrap.scss","../node_modules/primeicons/primeicons.scss","../node_modules/primeng/resources/themes/nova-light/theme.scss","../node_modules/primeng/resources/primeng.min.scss","../node_modules/@fullcalendar/core/main.min.scss","../node_modules/@fullcalendar/daygrid/main.min.scss","../node_modules/@fullcalendar/timegrid/main.min.scss","../node_modules/font-awesome/css/font-awesome.scss",
