I've got some problem with starting app by using 'npm start'. After create react files folder and using that command I can see:
npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! weatherapp#0.1.0 start: `react-scripts start`
npm ERR! Exit status 1
npm ERR!
npm ERR! Failed at the weatherapp#0.1.0 start script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.
I want to add that I've used react before. I was running code the same way but everything was good. What's the solution?
Make sure you are writing the npm start command to correct package where your package.json resides.
More likely it seems you don't have react script installed.
Can you try installing script with following command.
npm i react-scripts
This may solve your problem. Happy learning :)
Try to remove node_modules and package.log or yarn.lock file also. and run npm install again. Should solve your problem.

Your package.json file doesnt have scripts, so when you run npm run start, npm cant find the start script in it.
So, open and edit your package.json file and write a script in order to run it.
I had a similar problem. In my case, I had to go to the folder itself in which the project is located. As I understand it, in the C:\Users\Pooja Patel\Desktop\evalue webpage> folder you still have a folder in which the project is located. Just go into it and even then write npm start.
I tried starting a new react project and i kept getting this error

i have tried updating NPM but it just does not seem to work!
This worked for me:
npm cache verify
or you can try
npm cache clean --force
I had the same issue.
It worked for me after removing the spaces in the directories name,
e.g.
C:\Users\LENOVO\React Projects\webapp
becomes
C:\Users\LENOVO\React_Projects\webapp
i have troubles updating the new version of react-native which appears to improve vastly and a lot of features.
After reading this article :
https://facebook.github.io/react-native/blog/2018/07/04/releasing-react-native-056
I've started to run this command : https://facebook.github.io/react-native/docs/upgrading.html
All goes well, the application is built after running react-native run-ios
The problem is the bundle which is buggy :
node node_modules/react-native/local-cli/cli.js start "--reset-cache"
Scanning folders for symlinks in
/Users/julestruong/Dev/BAP/flex/v1/flex-mobile-app/node_modules (14ms)

Nothing works ...
If you're using typescript you'll need to upgrade react-native-typescript-transformer to 1.2.10 since metro moved the transformer it relies on.
I am new to React and I am trying to build a react app using create-react-app and Watson node-sdk. Everything works fine in development mode after running npm start. But when I try to build a production package using npm run build and below is the error I receive.

The line that giving error is let missing; and seems like the let is causing the issue. Is there anything I can do with this?
Encountered this problem today. the doc suggests some solutions:
Open an issue on the dependency's issue tracker and ask that the package be published pre-compiled.
Fork the package and publish a corrected version yourself.
If the dependency is small enough, copy it to your src/ folder and treat it as application code.
