The full error message is
<code>'node-sass' usage is deprecated and will be removed in a future major version. To opt-out of the deprecated behaviour and start using 'sass' uninstall 'node-sass'.</code>
So, I think the only solution that you can try is obvious, just uninstall node-sass.
=&gt; I already uninstalled it and tried <code>ng serve</code> and <code>ng build --prod</code> all is working fine.
FYI, I as a developer always have found this library <code>node-sass</code> as a pain in the head because of its incompatibility errors. I am happy that we don't have to use it and deal with its painful errors anymore.

After uninstalling I was still getting the same error.
I had a look at the source code, turns out the check is quite fragile:
<pre><code> try {
 sassImplementation = require('node-sass');
 wco.logger.warn(`'node-sass' usage is deprecated and will be removed in a future major version. ` +
 `To opt-out of the deprecated behaviour and start using 'sass' uninstall 'node-sass'.`);
 }
</code></pre>
Which means that, if you have node-sass installed globally, or in a parent directory somewhere, you'll get this warning.
To test this, make a new file in your project directory and run it with node:
<pre><code>const t = require('node-sass');

console.log(t);
</code></pre>
If you don't get module_not_found, it means it's node_sass is being resolved.
In my case I had node-sass installed under my user home directory.

You can replace node-sass with sass, which is the dart version of sass.
<h2>npm</h2>
<pre><code>npm uninstall node-sass
npm install sass
</code></pre>
<h2>Yarn</h2>
<pre><code>yarn remove node-sass
yarn add sass
</code></pre>
If you're using gulp, make sure to update your build script with the correct usage: <a href="https://www.npmjs.com/package/gulp-sass" rel="nofollow noreferrer">https://www.npmjs.com/package/gulp-sass</a>

当我从8升级到11时，我遇到了这样的警告‘node’的使用是不推荐的，并将在未来的主要版本中删除。若要选择退出不推荐的行为，请开始使用“sass”卸载“node”。有人能帮我吗提前感谢
