Node fs Error: EPERM: operation not permitted, open

*this is not an exact answer but may help:*

**i think** if you want to `read` or `readSync` a file that doesn't exist you will encounter an `EPERM` error...
> in many programming languages, any permission related error may not
> directly means an actual permission issue

for example in `PHP` Folders (not files) must delete by php `rmdir()` method but if you want to do that with `unlink()` , u will encountered with a wrong Warning message that says "permission denied"

On my Windows 10 machine, I encountered this error when running an old Node JS project. I think Node version 10.16.

In any case, it was trying to modify a dotfile in my project. Be sure that the file isn't hidden on Windows. After unchecking the hidden option in the file properties pop up. Everything worked.

So to fix:
1. Right click file in Windows Explorer
2. Select properties
3. Uncheck **Hidden**
4. Click **Ok**
5. Re-run your command.

I had the same problem, when i tried to create and write to a file using NodeJS. I thought it had to do with my windows file/folder access permissions, but after restarting my computer and running the code again, I still got the same error.

However, this time around my antivirus gave me a pop-up message also, stating that it blocked permission for **Node.exe** to write or open files. So once I flagged Node.exe as safe for my anti-virus program (Avast).

It worked for me. Disabling my antivirus could've also temporarily fixed it, I guess.

If you are facing this issue on Windows 10, then please try the following:

1) Uncheck **readonly** options for the folder (if read-only reverts, login as administrator)
2) Open terminal **as administrator** (if you are facing this issue on terminal)
3) **Switch off ransomware** folder protection
4) Change **chmod** of the folder
5) Check if the folder is **hidden** or not
6) Disable antivirus protection (**temporarily**) and try this
7) Or move your project folder somewhere else, where antivirus ransomware protection is disable.

If nothing above works, then try the following:

Hope this would of help.

I was facing the same problem using the following software:
- Windows 10
- GitBash
- Node v19

I was able to solve it opening GitBash as admin
