fs.rename() throws a permissions error

• Platform: 64-bit
• Subsystem: File System

When attempting to rename a file on my Windows 10 PC, I get the following error message:

...previous console output...
        throw err;
        ^

Error: EPERM: operation not permitted, rename 'C:\Users\Gum-Joe\.retis\plugins\.tmp\extract\retis-tester-1-master' -> 'C:\Users\Gum-Joe\.retis\plugins\.tmp\extract\retis-example'
  at Error (native)

I had a look at Medium/phantomjs#19, where one of the comments states that this issue is only on Windows, which is true for my issue as my program works on my Raspberry Pi, which runs Raspian.

Here is a small test case (~/ = windows home directory) :

1. Create the directory ~/.retis/plugins/.tmp/extract/test
2. Run this code:

const fs = require('fs');
const os = require('os');
fs.rename(
  `${os.homedir()}/.retis/plugins/.tmp/extract/test`,
  `${os.homedir()}/.retis/plugins/.tmp/extract/renamed`,
  (err) => {
    if (err) {
      throw err;
    }
  };

Thanks in advance!

I had no issues running the code you provided (after adding a parenthesis at the end) on a Win10 machine. The folder was renamed correctly with no errors thrown. Are you sure you don't have the folder open in a Windows Explorer, or a command prompt?

@claudiorodriguez I rebootes my PC and the issue was fixed! The problems was either:

1. I had a windows explorer or command prompt (git-bash for me) window open, or a file in the folder open in my text editor (atom).
2. The folder already existed, so I couldn't overwrite the folder (proven by testing).

Thank you for all the help!
