When I try to run my project I always get this error:
I've tried everything I've seen online, and it still fails. I've executed "npm install" and a lot of npm commands I've seen in similar questions online. I've updated npm, node.js and visual studio.
Please help me I'm desperate.
Thank you in advance.

Anonymous2022-03-10T06:04:24.003+00:00 Hi @Manuel Rom ,
From the error message, it seems that the react-scripts.js module was not found, try to check the package.json file whether it contains the
react-scriptsdependency, if not try to add it.If the package.json file contains the react-scripts dependency, try to search the
node_modulesfolder, whether it contains the react-scripts.js file.You can also try to remove the node_modules folder and the package-lock.json file, then, execute the
npm-installcommand to reinstall the relates dependencies and package.I create a new react application with the following package.json file, after install the relate dependencies and package, the application works well on my side:
The NPM script 'start' exited without indicating that the create-react-app server was listening for requests
Besides, for the above issue, I also checked some similar threads, it seems that if you have an
&in your project's path you will run into this issue, at least on Windows it seems like. The part in the path after the&is interpreted as another command as per the error and everything breaks from there. So, you can check your project's path and remove it if it contains&.Best regards,

2022-03-10T07:25:36.84+00:00 Hi, thank you for your answer. I have the react-script dependency and react-script.js folder in node-modules. I've tried your package.json file, run npm install and I still got the same error. The path in my project doesn't have any "&".

2022-03-10T09:57:04.94+00:00 Can you tell us your Asp.net core version, npm version, the VS version and the package.json file? It is better to create a simple sample, so that we can try to reproduce the problem and help you solve the problem.

2022-03-15T08:03:37.207+00:00 If I directly copy your package.json content in my application, it will also show the "Module not found error". But if I create a new project with the default configration, everything works well.
So, can you create a simple sample and tell us the detailed steps, so that we can try to reproduce the "The NPM script 'start' exited..." error.

2024-12-02T16:53:09.1866667+00:00 this is an old thread. react-scripts are no longer supported. the VS template replaced them with vite.

2022-03-15T15:04:14.1+00:00 You should delete the node_modules folder and run
npm install
Show us the output.
