Pyperclip: "When using gi.repository you must not import static modules like "gobject"

I am making a program that will allow my phone to share its clipboard with my PC. I am using Pyperclip as it appears to be the easiest and most cross-platform solution. However, when I run the code below:
...
elif "incoming_clipboard:" in server_command:
print(server_command)
pyperclip.copy(server_command.replace("incoming_clipboard: ", ""))
...
I get the error:
Exception in thread Thread-1:

I know its not due to the string being invalid or anything, because 1) I am explicitly converting it from bytes to a string, and 2) it prints perfectly fine. I don't know if this is relevant, but I am using Linux, so perhaps that is affecting Pyperclip?
Do you guys have any solutions?

https://github.com/dynobo/normcap/issues/100
After going to the Github page for PyperClip, I found a similar issue that someone else had that suggested switching to PyClip. After installing PyClip and implementing it in project, I can confirm that it works perfectly without any issues.

KeyboardInterrupt Exception

I'm having a hard time handling Exceptions in pycharm 3.8:
When I press ctrl+c running my program, it doesn't work, so I've been told to use pycharm console to test it, and it does work, interrupting the keyboard input.
def readFloat(msg):
while True:
try:
return float(input(f'{msg}'))
except (ValueError, TypeError):
print(f'\033[31mError. Not valid.\033[m')
continue
except KeyboardInterrupt:
print('\033[31mYou didn\'t type a number.\033[m')
return 0
b = readFloat('Your Number: ')
print(f'\nThat\'s your number: {b}')
But now, when I try to Control+C, it doesn't catch my except and print my custom error report, returning 0. It gives me some huge and red error lines:
Traceback (most recent call last):

console_thrift.KeyboardInterruptException: KeyboardInterruptException()
So I tried to add a generic exception just to print the error class, and I got this:
Error found: <class 'console_thrift.KeyboardInterruptException'>
So I can't manage to detect an except keyboardInterrupt and work with it, just using a generic exception, any ideas?
Edit
The only plugin that I added was a Theme UI to run pycharm totally black, the rest of them came with the instalation, I think. I ran the .py file using CMD and it works just fine, detecting the keyboard interrupt.

Try this:
try:
from console_thrift import KeyboardInterruptException as KeyboardInterrupt
except ImportError:
pass

Ref: Why doesn't this python keyboard interrupt work? (in pycharm)
The thing about IDEs is that they are not quite the same as running normally, especially when it comes to handling of keyboard characters. The way you press ctrl-c, your IDE thinks you want to copy text. The python program never sees the character. Perhaps it brings up a separate window when running? Then you would select that window before ctrl-c.

Unable to import opengl.gl in python on macos

I am using OpenGL to render a scene in python. My code works perfectly fine on windows but, for some reason, I'm having issues when importing opengl.gl on MacOS.
The issue arises when calling from OpenGL.GL import ... in both python scripts and the python console.
More specifically here is the exact call in my script:
from OpenGL.GL import glGenBuffers, glBindBuffer, glBufferData, \
glGenVertexArrays, glBindVertexArray, glEnableVertexAttribArray, glVertexAttribPointer, \
glDrawArrays, glUseProgram, glEnable, glDisable, \
GL_ARRAY_BUFFER, GL_STATIC_DRAW, GL_DEPTH_TEST, \
GL_FLOAT, GL_FALSE, \
GL_TRIANGLES, GL_LINES, GL_LINE_STRIP
This results in the following error:

Notes:
Running glxgears works just fine.
I'm running macOS Big Sur beta (20A5343i)
I'm using python 3.8.5
I installed opengl using pip: pip3 install PyOpenGL PyOpenGL_accelerate

This error is because Big Sur no longer has the OpenGL library nor other system libraries in standard locations in the file system and instead uses a cache. PyOpenGL uses ctypes to try to locate the OpenGL library and it fails to find it. Fixing ctypes in Python so that it will find the library is the subject of this pull request
https://github.com/python/cpython/pull/21241
So a future version of Python should resolve the problem.
To fix it now you can edit PyOpenGL file OpenGL/platform/ctypesloader.py changing line
fullName = util.find_library( name )
to
fullName = '/System/Library/Frameworks/OpenGL.framework/OpenGL'

Since I hate the idea of patching a Python package (plus it is really hard to manage that with use of Conda to install said package), I offer this kludge as a workaround for until Python gets its Big Sur (aka Big Nuisance) update:
try:
import OpenGL as ogl
try:
import OpenGL.GL # this fails in <=2020 versions of Python on OS X 11.x
except ImportError:
print('Drat, patching for Big Sur')
from ctypes import util
orig_util_find_library = util.find_library
def new_util_find_library( name ):
res = orig_util_find_library( name )
if res: return res
return '/System/Library/Frameworks/'+name+'.framework/'+name
util.find_library = new_util_find_library
except ImportError:
pass

It's better to change this to
fullName = "/System/Library/Frameworks/{}.framework/{}".format(name,name)
otherwise GLUT won't work. At least, this let me run the Cozmo SDK's 3d stuff again.

FYI, in my case it was:
fullName = '/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/System/Library/Frameworks/OpenGL.framework/OpenGL'

None of these are really very suitable answers - there were several issues with both MacOS and pyOpenGL.
Fortunately, however - everything seems to be working at last if we upgrade to Python3.10 (or above)

Different behaviour in normal and debug run in threaded Virtualbox

I'm encountering a weird error when running the script in PyCharm's debug mode or inside a Flask app. I have narrowed down my code to the following
import virtualbox
import threading
class ThreadExecutor(threading.Thread):
def __init__(self):
super().__init__()
def run(self):
vbox = virtualbox.VirtualBox()
if __name__ == '__main__':
th = ThreadExecutor()
th.start()
Running this as a module produces no errors and executes perfectly fine but in debug mode it produces the following error message
Connected to pydev debugger (build 181.5087.37)
Exception in thread Thread-6:

pythoncom.RPC_C_AUTHN_LEVEL_DEFAULT,
pythoncom.RPC_C_IMP_LEVEL_IMPERSONATE,

pythoncom.EOAC_NONE,
None)
except:
_, oXcpt, _ = sys.exc_info();
if isinstance(oXcpt, pythoncom.com_error) and self.xcptGetStatus(oXcpt) == -2147417831: # RPC_E_TOO_LATE
print("Warning: CoInitializeSecurity was already called");
else:
print("Warning: CoInitializeSecurity failed: ", oXctp);
What's causing this error? Does sys.exc_info() behave differently inside a thread inside a debugger?

There seems to be some known, unresolved issues in the interaction between threading and virtualbox, see here. I would suggest using multiprocessing instead as I have not experienced any of the previous issues with it.

How to correctly import latest libarchive for use on Mac OS

The release notes for libarchive state that because of an older version of libarchive being included within MacOS they recommend changing LD_LIBRARY_PATH to point towards the location of the recent copy of libarchive.
I've used this code to try and achieve that but I get an error message when I run the script.
import os
print os.environ.get('LD_LIBRARY_PATH') #Check what the current path is
os.environ['LD_LIBRARY_PATH'] = '/Library/Python/2.7/site-packages/'
print os.environ.get('LD_LIBRARY_PATH') #Check the variable has been set
import libarchive.public
Error:
None

AttributeError: dlsym(0x7fb08b741000, archive_read_support_filter_all): symbol not found
I cant find a great answer to this anywhere out there.

It is not clear from the tool documentation, but based on a thread: https://github.com/dsoprea/PyEasyArchive/issues/16 I set another environment variable to the place where the underlying c library could be found. In my case, it was put there by homebrew on my mac.
os.environ['LA_LIBRARY_FILEPATH']='/usr/local/opt/libarchive/lib/libarchive.dylib'
import libarchive.public
worked for me.
