Project Initialization Error: Cannot find module 'simple-swizzle'

ajayps · September 10, 2025, 2:23am

Hi Team,

When I initialized my project and tried to run npm run start-dev, I encountered the following error:

Error: Cannot find module ‘C:\Users\91628\neutrinos-studio\library\server\node_modules\simple-swizzle\index.js’.
Please verify that the package.json has a valid “main” entry
at tryPackage (node:internal/modules/cjs/loader:487:19)
at Module._findPath (node:internal/modules/cjs/loader:771:18)
at Module._resolveFilename (node:internal/modules/cjs/loader:1211:27)
…
Node.js v20.18.3
[nodemon] app crashed - waiting for file changes before starting…

Steps I already tried:

Deleted node_modules and reinstalled using npm install.
Checked package.json for any missing dependencies.
Tried installing simple-swizzle manually using npm install simple-swizzle.
Re-ran the project with npm run start-dev.

But the issue still persists.

Could you please guide me on how to properly resolve this missing module error?
Is there any specific setup step required while initializing Neutrinos projects that I might have missed?

@Sam @Simphiwe @Shamnad_KS can you please support

Hello @ajayps ,
Could you please confirm whether this issue is occurring in the UI application or the API application?

Sam · September 10, 2025, 4:28am

Hello @ajayps ,
If the issue still exists, could you please share the repository link containing the project folder with me privately, so that we can debug the issue from our side?

Issue occurring in the API application

Sam · September 10, 2025, 4:54am

Hello @ajayps ,
Could you please share the repository link with me privately?
and please specify the node version and studio version

Hello @ajayps ,
I tried to reproduce the issue, but it could not be observed on my end. Could you please uninstall and reinstall Neutrinos Studio, and then check again to see if the problem persists?

Hi Ajay,

This issue is linked to recent npm package problems. Please try the following steps:

Run:

npm cache clean --force
npm cache verify
rm -rf node_modules package-lock.json

Pin safe versions in package.json .
Reinstall:

npm install

Verify with:

npm ls simple-swizzle
npm audit

This should resolve the missing module error.

I reinstalled the Studio application and started a new project, but that project also faced the same issue. I then followed all the steps you mentioned above, but the issue is still not resolved. The command execution screenshot and error details are attached in the screenshot for reference.

Hello @ajayps ,
Could you try this

ajayps · September 10, 2025, 7:33am

Yes, I tried these steps, and the screenshots of those steps are mentioned above, but the issue is still not fixed.

Hello @ajayps ,
It seems the command is not working in PowerShell. Could you try running it in Git Bash and go through the commands to check if it works?

vyshakh_k · September 10, 2025, 8:19am

@ajayps studio is using command shell in windows . use this command rmdir /s /q node_modules
del /f /q package-lock.json
instead of “rm -rf node_modules package-lock.json”

ajayps · September 10, 2025, 8:51am

I tried these steps in different shells — the default Studio terminal, Windows PowerShell, and Git Bash — but there was no change in the issue. Even a new project is not working because of this problem.

vyshakh_k · September 10, 2025, 9:20am

i’am also facing this issue , and i tried to create new api app that also produce this error

Sam · September 10, 2025, 10:44am

Hello @vyshakh_k could you please send your project as a zip file privately? We need to check the node modules.

Sam · September 10, 2025, 1:27pm

Hello @ajayps @vyshakh_k ,
It seems to be an internal issue. The team is already working on it and it will be fixed soon.

ajayps · September 11, 2025, 6:58am

Is this issue resolved?

Sam · September 11, 2025, 7:34am

Hello @ajayps ,
In the affected project, please try running these commands once more and check if the issue persists. Also, create a new project and let us know whether the issue occurs there as well

npm cache clean --force

npm cache verify

rm -rf node_modules package-lock.json

npm install

ajayps · September 11, 2025, 8:51am

I tried the following steps in the current project and also created a new project, initialized it, and checked the live view. The same issue persists. I also applied the above command, but it didn’t work. The issue is still not resolved. The command execution and project run error screenshots are attached below.
