Node-sass, node-gyp errors, how to fix?

Question

After updating the brew and reinstalling node, an error occurs when setting the dependencies. Tell me how to solve this?

The code below is not the entire error, there is only a part since there is a limit on the number of characters.

node v10.2.1

PHP 7.2.6 (cli) (built: May 25 2018 06:18:43) ( NTS )

Python 2.7.10 (default, Oct 6 2017, 22:29:07)

Answer 1

Make sure your node version supports your node-sass version.

Look at your package.json and see if "node-sass": "^X.X.X", matches your node version according to the linked table.

Also, make sure you're running the node version you want to run. Check with which node and if you're using nvm or n, dont forget to

nvm use X

or

n X

where X is the required node version.
