Question

I\'m trying to learn react, so I have this sample code for the full-stack react voting app, and I am trying to get it to work but after running npm install followed by npm s

Answer 1

React Application: For me the issue was that after running npm install had some errors.

I've went with the recommendation npm audit fix. This operation broke my package.json and package-lock.json (changed version of packages and and structure of .json).

THE FIX WAS:

• Delete node_modules
• Run npm install
• npm start

Hope this will be helpfull for someone.

Answer 2

I recommend you update your node version to the latest node version recommended by your application or for short update your node version. I encountered this same problem using node version 11.1 but my application was recommending atleast version 10.x.x or 12.x.x I tried all the suggested reply on this thread but non seemed to work for me untill only when i updated my node version to the recommended latest version .i.e. version 12.16.3 then my application ran.

Answer 3

Cleaning Cache and Node_module are not enough. Follow this steps:

• npm cache clean --force
• delete node_modules folder
• delete package-lock.json file
• npm install

It works for me like this.

Answer 4

I was getting similar error messages on a 16.04 Ubuntu instance with DigitalOcean while running npm run build on an app made with create-react-app (link). I upgraded the instance from 512MB RAM to 1GB ($5/mo to $10/mo) and then the script was able to run.

I post this here to point out that you may get this error due to resource limitations, which I didn't really see explained elsewhere on issue pages and SO answers. And nothing I saw in the error logs pointed me in this direction.

Answer 5

Its weird but it works for me

Go to

control panel -->System and Security--> System --> Advanced System Security--> Environment Variables

In Environment Variable popup you will edit the user variable PATH and add "C:\Windows\System32" value as semicolon separated to the existing value.

Not but not least restart the Machine.

Answer 6

A possibly unexpected cause: you use Create React App with some warnings left unfixed, and the project fails on CI (e.g. GitLab CI/CD):

Treating warnings as errors because process.env.CI = true.
[ ... some warnings here ...]
npm ERR! code ELIFECYCLE
npm ERR! errno 1

Solution: fix yo' warnings!

Alternative: use CI=false npm run build

See CRA issue #3657
