Infinite styles compiling (create-react-app and node-sass)

So we have a project which uses create-react-app and node-sass.

I have encountered this error many times over the last 2-3 months. I thought it was only happening to me, but now my colleague sometimes encounters this issue as well.

---

We have a standard setup from Adding a CSS Preprocessor (Sass, Less etc.).

---

Actual problem occurs when I edit the styles.scss and save them. Then an infinite compiling loop takes place. It’s seriously annoying and it uses a lot of memory as well.

Has anyone had encountered that problem and any ideas how to fix it?

Example

[JasonGoemaat]

node-sass seems to detect the css file changing. I changed the script to only look for scss files and it worked for me:

"watch-css": "npm run build-css && node-sass src/*.scss -o src/ --watch --recursive",

i had same problem in vscode, and resolved use by add code --usePolling --polling-interval 500

now my package.json script is

"build-css": "node-sass-chokidar --include-path ./src --include-path ./node_modules src/ -o src/",
"watch-css": "npm run build-css && node-sass-chokidar --include-path ./src --include-path ./node_modules src/ -o src/ --watch --recursive --usePolling --polling-interval 500"

it’s run successfully in vscode
