Just upgrade your **sass** version in your `yarn.lock` file.
For node 14 the appropriate version for `node-sass` is `4.14`.
So adapt to your node version.

Faced the same issue. If you look at the error stack, it says:
```
Error: Command failed: /usr/bin/python3.6 -c import sys; print "%s.%s.%s" % sys.version_info[:3];
File "<string>", line 1
import sys; print "%s.%s.%s" % sys.version_info[:3];

It's trying to use Python2 but instead uses Python3 which is not supported.

My system runs Python3 when called using the `python` command, so I fixed this by installing Python2 and aliasing it to the `python` command:
```bash
alias python=pyhton2.7
```

I had the same issue upgraded the node-sass version to be the same as node version. with yarn just run:


yarn add node-sass

this will upgrade the version and fix the issue

I solved this issue by installing the python 2.7 version on windows os.I had Python 3 installed before. This error happens because of the python version 3.

Solutions here don't work for me.
Until I delete the node_modules folder and yarn.lock.

rm -rf node_modules
rm yarn.lock
yarn instal

I ran into this issue when containerising a VueJs app.
I was using the node:15.12.0-alpine tag as base image before but the issue was fixed once I changed to the full node image (node:15.12.0) that uses debian-stretch.

Install `node-sass` globally with `yarn`

Or
Add `node-sass` to your project

I am running `Rails 6` and for some reason it was pulling `webpacker 4.3.0` which was pulling `node-sass 4.3.0` rather than `6.0.0` which is the latest as of the date of this post.

What worked for me is the following:

1. Deleting the `node_module` folder, `package-lock.json` and `yarn.lock`
2. In my `package.json`, I upgraded `rails/webpacker: 5.3.0`.
3. I then re-ran `yarn install`.
4. Then I ran `yarn add node-sass`

That worked like a charm, after trying everything else above.

I believe those were the exact steps, although to be honest I have been trying sooo many things and they didn't work and I finally got it to work so there is a possibility I may have missed a step, but I did my best to re-create it for any future frustrated soul out there.

****python = "**localpath**/python27/python.exe"
