flymake-proc alway running while edit python file

[chenpoyang]

while edit python file in elpy-mode, an applet always pop up(ps aux | grep python), in emacs, it's flymake-proc(flake8 maybe), and Elpy Output:

Output from Backend

There was some unexpected output from the Elpy backend. This is usually some
module that does not use correct logging, but might indicate a configuration
problem.

Output

(process:86782): Gtk-WARNING **: Locale not supported by C library.
    Using the fallback 'C' locale.

LC_ALL is: en_US.UTF-8 LANG is: en_US.UTF-8 how to fix it?

Just to be sure this is an Elpy related problem:

• Is this also appearing for other gtk applications ?
• the Gtk-WARNING **: Locale not supported by C library. is well known, have you tried some of the solutions proposed for example here.

As this is only a warning, I suppose that flake8 still works ? So you are just annoyed by the pop-up ?

If it is really annoying, you can add the following snippet to your "init.el" to prevent elpy for popping up messages (as a temporary solution):

(defun elpy-rpc--handle-unexpected-line (line)
  "Handle an unexpected line from the backend.

This is usually an error or backtrace."
  (message "[Elpy backend output] %s" line)) 

(should work, untested)

while edit python file: str = "some string" str. "str." auto complete show a list view, and a frew seconds, an applet pop up in docky. after i add the code to init.el, still pop an applet:

(defun elpy-rpc--handle-unexpected-line (line)
  "Handle an unexpected line from the backend.

This is usually an error or backtrace."
  (message "[Elpy backend output] %s" line)) 

emacs Elpy Output is:

Output from Backend

There was some unexpected output from the Elpy backend. This is usually some
module that does not use correct logging, but might indicate a configuration
problem.

Output

(process:54183): Gtk-WARNING **: Locale not supported by C library.
    Using the fallback 'C' locale.

the applet in docky's image like:python applet(a rocket) system, uname -a:

You should add it after Elpy is loaded, to overwrite the real python-shell-send-region. But as I said, this is a temporary solution, you really should go to the bottom of your gtk error.

while run emacs in terminal instead of xemacs, just a python process launch(an applet pop):

2017-12-06 08:01:33.077 Python[54183:9772687] *** WARNING: Method userSpaceScaleFactor 
in class NSView is deprecated on 10.7 and later. It should not be used in new applications.

the process id is :54183

so the problem may be:

There was some unexpected output from the Elpy backend. This is usually some
module that does not use correct logging, but might indicate a configuration
problem.
