make: *** [makefile:14: format] Error 1

We have something similar issue listed here: https://bugs.python.org/issue17023

The file is there, the path is fine too.
But why am I getting this error as the file is there at the specified location?

I`m getting this error while running formatter linters.

IMPORTANT NOTE:- In case of any modification made to the library file, it might cause compatibility issues later on with codes for other programmers.
To get more information, about the necessity to set value for the shell, plz refer to the official docs, proper link is provide here.

As this error caused trouble in my work I did the following solution for now and everything is working fine for me.

To solve this error:-
We have to modify the subprocess.py in your environment.

First of all, you have to locate this file and then edit it.
In my PC it location is – C:UsersUserAppDataLocalProgramsPythonPython39Lib.

In this piece of code:-

def __init__(self, args, bufsize=-1, executable=None,
             stdin=None, stdout=None, stderr=None,
             preexec_fn=None, close_fds=_PLATFORM_DEFAULT_CLOSE_FDS,
             shell=True, cwd=None, env=None, universal_newlines=False,
             startupinfo=None, creationflags=0,
             restore_signals=True, start_new_session=False,
             pass_fds=(), *, encoding=None, errors=None):

You have to change the value of shell.
Change shell=False to shell = True.

This solution worked for me, I hope it`ll work for you too.

Thank you.

Answer 2

You can just set shell = True and pass it to the subprocess class you are using. Modifying the library file will cause compatibility problems later on with codes from other programmers.
To get some insight into why we need to set this variable, take a look at the documentation:
"args is required for all calls and should be a string, or a sequence of program arguments. Providing a sequence of arguments is generally preferred, as it allows the module to take care of any required escaping and quoting of arguments (e.g. to permit spaces in file names). If passing a single string, either shell must be True (see below) or else the string must simply name the program to be executed without specifying any arguments."
