I'm trying to run my back-end code on the local host. It was functioning perfectly until I added a video into the folder and ran a python program which used the video to output results which should be displayed on the localhost.
Before I ran the python program I installed opencv, python 3 and pip3.
All my other team members have the exact same structure and code and it is working perfectly for them.
After all this, I'm getting is this error:
C:\Third_Year\IBM_project\ibm\back_end>npm start

I've tried
Running; npm cache clean --force
Deleting node_modules folder and package-lock.json file by running:
rm -rf node_modules package-lock.json
Or deleting it manually by going into the directory and right-click > delete / move to trash.
Running; npm install then to start again run; npm start
However this did not fix my problem, any other suggestions?

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've had my personal website made with React published on Github pages for about a year now and I would always update it using the following commands:
git add .
git commit -m "update"
npm run deploy
git push -u origin main
The last time I was able to run these commands without fail was last week. Since then, the only changes I've done to the repo are changing the repo name on Github but now I'm unable to run the same commands without receiving a 403 error. In the end I decided to start a new repo but now I get the following error:
fatal: A branch named 'gh-pages' already exists.
npm ERR! code ELIFECYCLE

Try to check you path variable, in this case, it should be C:\Windows\System32, If not, you can reference the answer of Saket, If still not work for you, only one way is that you need UNINSTALL current version and re-install again, it will fix.
You can solve this using below steps-
step 1: Run $ npm cache clean --force
step 2: Delete node_modules folder and package.lock.json
step 3: Run npm install
These could solve the issue !

i have already tried these options
npm cache clean --force
reinstalling npm and node
switching different version of npm
error which I get while installing create-react-app other packages installed properly
the error npm ERR! shasum check failed and npm ERR! Unexpected end of JSON input while parsing near'....' , will be solved by switching npm reigistry from the list of given npm registry.
List of Npm registry:
https://registry.npmjs.org/ (Dfault One)
http://r.cnpmjs.org/
https://registry.npm.taobao.org/
https://registry.nodejitsu.com/
http://registry.mirror.cqupt.edu.cn
https://skimdb.npmjs.com/registry
https://npm.open-registry.dev/ (https://open-registry.dev)
To switch just type
npm config set registry "https://registry.npmjs.com/"
Replace the registry url with the above urls check which one works for you.
After That:
npm cache clear --force
npm cache verify
now error will be solved.
"npm cache clean --force" didn't work for me but removing package-lock.json worked.
https://github.com/vuejs-templates/webpack/issues/990#issuecomment-395750082
Error:
SyntaxError: Unexpected end of JSON input while parsing near
Removing package-lock.json worked for me.
Add Powershell script or Linux script as below,
Powershell:
Remove-Item package-lock.json -Force
Linux:
rm -rf package-lock.json
Path In Azure Devops:
$(System.DefaultWorkingDirectory)\appName\appName\ClientApp\node_modules'
Note - appName is an example you can add a path as per your source code.
