See original GitHub issue

Describe the bug

“react-scripts start” is giving error . It was working fine yesterday. From today it’s getting failed.

react-scripts start

Unexpected token { npm ERR! code ELIFECYCLE npm ERR! errno 1 npm ERR! flexi@1.0.0 start: react-scripts start npm ERR! Exit status 1 npm ERR! npm ERR! Failed at the flexi@1.0.0 start script. npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

npm ERR! A complete log of this run can be found in:`

Did you try recovering your dependencies?

Yes . i tried

rm-rf ./node_modules npm cache clean -f npm install …all such combination

Have you done all these steps and still see the issue? npm -v ===> 6.13.4 node -v ===> v10.17.0 os ===> mac And also I tried to copy and use the package.json and package.lock.json and tried in my reop. Even then it’s the same.

Some dependency of react-scripts is badly fucked up.

###Important observarion in create-react-app

react-scripts build works fine
When you clone the repo and do npm install the package.lock.json get updated. Ideally that should not be the case as far as I know.

###What all I searched I searched all related threads (https://github.com/vuejs/vue-cli/issues/2596 …) none worked for me.

My submission would be some version of npm is fucked up because it gave me unexpected token import with npm 5.0.1
