Hi,

import fcntl
ModuleNotFoundError: No module named 'fcntl'

any solution

Same here with Windows 7 64 bit. This answer at StackOverflow provides an explanation. It seems fcntl module is not available on Windows. restatic won't work on Windows unless there is a workaround, or dependency to that module is removed in a future version.

A temporary and potentially dangerous hack, but it allows restatic to launch at least...

Create a file named fcntl.py with the following content and place it in a place python can find it.

def fcntl(fd, op, arg=0):
    return 0

def ioctl(fd, op, arg=0, mutable_flag=True):
    if mutable_flag:
        return 0
    else:
        return ""

def flock(fd, op):
    return

def lockf(fd, operation, length=0, start=0, whence=0):
    return

LOCK_EX = 2
LOCK_NB = 4

I didn't test the functionality, but it looks like use of fnctl in the code is quite localized. It is used only during startup to ensure single app instance. So I don't think the functionality is affected by this hack. Needless to say, your mileage may vary. Please try at your own risk.
