在我的angular-cli项目中从node-sass切换到dart sass

标签： angular sass dart node-sass

在“ npm安装”过程中，node-sass在进行各种愚蠢操作时一直遇到问题，包括但不限于：

  • GNU c ++编译某些内容（可能是本身）
  • 尝试运行python2.7
  • 尝试运行任何其他版本的python
  • 尝试连接到github

这在公司环境中造成了问题，我必须在Jenkins上编译我的项目，其中必须从公司服务器上npm注册表的克隆中提取NPM库，并且泊坞窗上只有该特定项目的严格必要性所以：

  • 没有github
  • 没有python
  • 没有c ++

并且我决定我已经有足够的node-sass的恶作剧，所以我尝试了建议的“ dart-sass”，因为这种想法似乎是完全与角度兼容的，并且旨在解决大多数问题。 node-sass：https://sass-lang.com/dart-sass

我尝试删除node-sass并将dart-sass代替了它：

npm remove node-sass
npm install dart-sass
ng serve

但这会导致：

Module build failed (from ./node_modules/sass-loader/lib/loader.js):
Error: Cannot find module 'node-sass'

针对项目中的每个组件。

为什么它仍在寻找node-sass？

这是在dart（js框架）下添加sass的方法，顺便说一句：Is Dart integrated with SASS?

但该方法不适用于角度。

更新：

我尝试使用了How to find reverse dependencies on npm package?

弄清楚尽管我已尽力而为，但仍在依赖/拉动节点-sass，结果是：@ angular-devkit / build-angular

但是，如果我删除该消息，则ng服务并不满意。它说需要它。

答案 0 :(得分：4)

FWIW，为了获得angular 7.x以使用sass软件包而不是尝试安装node-sass，我不得不：

  1. 从我的package.json中删除@angular-devkit/build-angular
  2. 删除node_modules
  3. npm安装
  4. npm i -D sass
  5. 将@angular-devkit/build-angular的0.13.10重新添加到package.json
  6. 再次安装npm。

答案 1 :(得分：2)

@angular-devkit/build-angular支持dart sass，只有您使用的模块错误，请尝试将npm install sass中的dart-sass应用于df['col3'].str.strip(',').astype(int) df col1 col2 col3 1 x 12,123 2 x 1,123 3 y 45,998 df col1 col2 col3 1 x 12123 2 x 1123 3 y 45998 。
