@peterennis If you're running from cmd/powershell can you try to open it as an administrator and run npm start again ?

[peterennis]

@NikolaPeevski

Same error when cmd is run as administrator.

[NikolaPeevski]

@peterennis with the terminal still opened as an administrator can you try running:

• npm cache clean
• npm start

Otherwise you can check out which process is locking the file as explained here and close it. It's a windows issue with npm.

[peterennis]

cache clean needs --force
same error

[peterennis]

terminated node process with resmon.exe
run again as administrator
same error

[NikolaPeevski]

Other things you can try are:

• If you have any anti-malware software disable it and reboot your system

• Completely delete the repo, clone it, npm install and npm start as administrator

[peterennis]

@NikolaPeevski

Shutdown/restart
Run npm start as administrator
now shows this:

Is that what is expected?

[NikolaPeevski]

@peterennis Congrats and yes, that's what you should see. The ReadMe explains what you could do from there on, for example check out some of the components.

This issue should be closable now ?

[peterennis]

@NikolaPeevski

Thanks for the tips.
