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.
