PermissionError: [WinError 5] Access denied: 'C:\\Users\\Lenovo\\Desktop\\Python\\Apps\\reflex-python2\\.web\\public'
[19:26:54] Reflex app stopped. 

Expected behavior To run the Reflex app as supposed.

Specifics:

• Python Version: 3.12.4
• Reflex Version: 0.5.9
• OS: Windows 11

Other The issue temporarily resolved by running attrib –s –r “Folderpath” in cmd. However after re-running Reflex it generates WinError 5 again and the command above should be run once again.

It seems like the process does not have permission to access the folder. Did you try to run the app with administrator?

[Brave-new-w0rld]

Yes, I run my PyCharm IDE as admin. The issue temporarily resolved by running attrib –s –r “Folderpath” in cmd. However after re-running Reflex it generates WinError 5 again.

windows 11, my fix, work fine: reflex\utils\path_ops.py

import stat

def remove_readonly(func, path, _):
    os.chmod(path, stat.S_IWRITE)
    func(path)

def rm(path: str | Path):
    """Remove a file or directory.

    Args:
        path: The path to the file or directory.
    """
    path = Path(path)
    if path.is_dir():
        # shutil.rmtree(path)
        shutil.rmtree(path, onerror=remove_readonly)
    elif path.is_file():
        path.unlink()

It works fine for me! Thanks man! Suppose as a fix for developers
