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.

Answer 1

Node.js dependncy table

Supported Node.js versions vary by release, checkout Node version support policy

Simply use nvm to switch to the correc version and run npm install. Additionally, consider adding a .nvmrc file so others can see required version in the project.

NodeJS	Supported node-sass version	Node Module
Node 19	8.0+	111
Node 18	8.0+	108
Node 17	7.0+, <8.0	102
Node 16	6.0+	93
Node 15	5.0+, <7.0	88
Node 14	4.14+	83
Node 13	4.13+, <5.0	79
Node 12	4.12+, <8.0	72
Node 11	4.10+, <5.0	67
Node 10	4.9+, <6.0	64
Node 8	4.5.3+, <5.0	57
Node <8	<5.0	<57

Answer 2

The key lines in the log stream might be:

gyp verb check python checking for Python executable "python2" in the PATH
gyp verb `which` failed Error: not found: python2

I'd suggest installing python2 (or setting an environment variable to point to it).

N.b. node-sass is depreciated

Answer 3

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.
