 npm WARN deprecated [email protected]: Please upgrade  to version 7 or higher.  Older versions may use Math.random() in certain circumstances, which is known to be problematic.  See https://v8.dev/blog/math-random for details.
    npm WARN deprecated [email protected]: Legacy versions of mkdirp are no longer supported. Please update to mkdirp 1.x. (Note that the API surface has changed to use Promises in 1.x.)
    npm WARN deprecated [email protected]: CoffeeScript on NPM `enter code here`has moved to "coffeescript" (no hyphen)
    npm WARN deprecated @types/[email protected]: Types for the Google Maps browser API have moved to @types/google.maps. Note: these types are not for the googlemaps npm package, which is a Node API.
    npm WARN deprecated [email protected]: no longer supported
    npm WARN deprecated [email protected]: This version of tar is no longer supported, and will not receive security updates. Please upgrade asap.
    npm WARN deprecated [email protected]: TSLint has been deprecated in favor of ESLint. Please see https://github.com/palantir/tslint/issues/4534

    npm WARN deprecated [email protected]: core-js@<3.4 is no longer maintained and not recommended for usage due to the number of issues. Because 
    of the V8 engine whims, feature detection in old core-js versions could cause a slowdown up to 100x even if nothing is polyfilled. Please, 
    upgrade your dependencies to the actual version of core-js.
    npm WARN deprecated [email protected]: We have renamed the @ckeditor package. New versions are available under the @ckeditor4 name.

Answer 1

试试这个： yarn add node-sass 然后 yarn 它对我有用

Answer 2

只需从 package.json 中删除 node-sass 然后运行 npm i -f 他就能正常工作。

Answer 3

要修复 node-sass 问题，请将 "node-sass": "xx.xx.x" 更改为 "sass": "^1.49.0"项目根目录中的 >package.json 文件。然后运行 ​​npm i 来安装新包。

尽管 node-sass 可能不是 ngx-admin 现在运行的唯一问题。
