Answer 1

Commands npm uninstall node-sass && npm install node-sass didn't help me, but after installing Python 2.7 and Visual C++ Build Tools I deleted node_modules folder, opened CMD from Administrator and ran npm install --msvs_version=2015. And it installed successfully!

This comment and this link can help too.

Answer 2

I tried this but it didn't work for me and threw errors:

npm --depth 9999 update 
npm rebuild node-sass

I have installed the latest Node.js (which for the moment is 11.11.0 Current), after facing this problem I just did the following:

1. downgrade to recommended version (which for the moment is 10.15.3 LTS),
2. deleted node_modules and
3. then reinstall yarn:

     yarn install
     yarn start

After executing these commands everything is working fine for me.

Answer 3

This error message does not indicate an problem with Ionic, but rather with node-sass, which is specified to execute in your Gulp file. The node-sass error, Node Sass does not yet support your current environment indicates that the version of node-sass you are trying to run is not compatible with the version of node installed.

Check the Node Sass release notes for the version of node-sass you have, to see which version of node is required. If the version of node is wrong, you must downgrade node, or upgrade node-sass, until you have a compatible pair. If the node version is supported, you may just need to run npm rebuild node-sass (with -g if node-sass was installed globally). If that doesn't work, you can npm uninstall node-sass && npm install node-sass (again, with -g if necessary).

This github issue has lots more info on this.

Answer 4

Working for me only after installing Python 2.7.x (not 3.x) and then npm uninstall node-sass && npm install node-sass like @Quinn Comendant said.

Answer 5

Removing node_modules and running npm install fixed those errors for me.

Others say: npm rebuild node-sass might help.

Answer 6

In my case the issue was when I installation of the node latest version i.e; 10.6.0. The same error was showing and with reference to @Quinn Uninstalled that version and installed the 8.11.3 LTS version. Now working Fine :)
