Error: EBUSY: resource busy or locked, open 'D:\my-project\source\js\bundle.js'

[auseidon986]

System: Windows 10 - Windows NT: 10.0.22621

Node version: v12.20.0

Command: npx watchify -o ./source/js/bundle.js ./source/js/main.ts -p [ tsify --noImplicitAny ] > ./source/js/bundle.js

Error: [Error: EBUSY: resource busy or locked, open 'D:\my-project\source\js\bundle.js'] { errno: -4082, code: 'EBUSY', syscall: 'open', path: 'D:\my-project\source\js\bundle.js'

As I check with Resource Checker, it appears that 2 cmd.exe and node.exe are accessing bundle.js. If I kill node project, nothing process then holds this file.

I googled for a while, and suggestions are

• npm cache clean --force
• Uninstall any malware software (I do not have one)
• Disable Windows Defender

But none of above solutions worked for me.

I guess this could be watchfy and windows os specific problem, so decided to post here. Please help me out.
