"sh: 1: react-scripts: not found" In Docker
I have a similar issue and I managed to work around by changing:
"start: "react-scripts start"
to:
"start: "./node_modules/.bin/react-scripts start"
in the scripts section package.json.
I use the classic node base image but it should work more or less the same.
And I am still investigating why NPM is not able to resolve react-scripts when running inside Docker, any further help is very welcome :-)
