npm cache clean, npm installBump.
This dependency error keeps popping up for me... last time it happened was like 4 months ago. Just happened again. Really frustrating problem, please fix.
EDIT: I fixed this by upgrading to the latest version of npm.
sudo npm install -g npm@latest
npm install
reboot
After trying @jscul's tip I'm still having this problem. Any other advice?
removing node_modules, npm cache clean
Thanks @bugzpodder and I should have listed this in the original post (I'll update it) but I've tried
npm cache clean, npm installAnd no luck
Same problem here! It's occurring even in a clean docker image with latest NodeJS and npm.
Docker image doesn't have create-reacte-app installed.
do you use sass?
we had the problem that react-scripts test --env-=jsdom not building the css files. Solution was to build sass first eg. node-sass --include-path ./src --include-path ./node_modules src/ -o src/
@ldaume we aren't using sass
Thanks @pedromelo98 but I've tried everything in #6886 with no luck
Same issue here. Ran npm cache clean, npm install. Updated npm and create-react-app
The issue appears to have to do with react-scripts being installed globally, and looking for packages globally which are installed locally. If you globally install @csstools/normalize, then it will fix the issue (although I had other errors in this case).
I ended up installing react-scripts locally, and running it via node (node node_modules/react-scripts/bin/react-scripts.js build) and this worked fine.
Complementing @KthProg:
I think it's no necessary install @csstools globally. For our team, this issue seems to be intrinsic related to npm version and create-react-app global dependency in the build machine.
We were facing this problem in a dock container and in a physical build server where isn't possible to retain global npm modules installed.
We managed to resolve this issue using the following steps:
npm run eject command (from react-scripts) to incorporate all React dependencies in both package.json and package-lock.json(at this points, the error still persists but the React project is completely independent of create-react-app) 鈿狅笍
Then we updated npm version from 5.6.0 to 6.9.0 (maybe the most important step 鉂楋笍)
Finally, we ran the npm run build command and everything worked perfectly.
(at this point all packages related to @csstools become available to node_modules)
I had the same issue today (on W8.1), solved it with:
