How can I fix node-sass usage is deprecated?

Question

Node-sass does not work. I see a message that node-sass is deprecated and will be removed in a future major version. I already uninstalled many times with no effect. I could still uninstall again. How could I solve?

Aside from the obvious "if this isn't your own code, but some framework's start project: use their latest version", if that is not the case you can use the npm-ls command to generate the full dependency tree for your project.

1. Use npm ls --all > dependencylist.txt to write that tree to a text file you can just open in your editor, then
2. find any mention of node-sass in dependencylist.txt, and
3. look up in the tree to find out which of your direct dependencies has a deeply nested indirect dependency on node-sass. Then
4. update those dependencies to their latest versions,
5. delete your node_modules dir, and finally
6. rerun npm install.

And of course, remember to never install anything globally, so if you made the mistake of installing node-sass using the -g flag, you'll have to also remember to uninstall it globally with that same -g flag.
