I'm running into an issue with cx_Freeze when running a frozen application (works fine unfrozen).
When running the program it results in the following traceback:
Traceback (most recent call last):

from _sre import MAXREPEAT
ImportError: cannot import name MAXREPEAT
I'm on linux using a version of python 2.7.4 that I built from source, and importing _sre from a prompt works and I can access the MAXREPEAT constant.
This is usually down to cx_Freeze not pulling everything into library.zip and can be fixed by explicitly naming the module in cx_Freezes setup include list and is the solution to this similar question, but that hasn't helped here.
This _sre module seems weird.. there's no _sre file in the library.zip generated but from that error it seems like it can find it, however it can't import that symbol? Surely if the module wasn't there it would be a "No module named _sre" error. Or possibly a circular import but _sre stub doesn't have any imports.
What's odd is I can't seem to find the file either - is this module dynamically created when importing somehow?
find /usr/local/lib/python2.7 -name "_sre*"
doesn't return anything, and the imported _sre module doesn't have a __file__ attribute either, so I've no idea how to make sure it's included as it shows up as a built-in.
>>> import _sre
>>> _sre.__file__
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: 'module' object has no attribute '__file__'
>>> repr(_sre)
"<module '_sre' (built-in)>"
This is similar to this question also which was asked recently, but in this case he was getting the error in the regular interpreter, however for me it's just in cx_Freeze.
edit
Running python -v does seem like it's a built-in, so I'm not sure why cx_Freeze can miss it, or how I'd fix it.

I encountered this problem when I just upgraded from ubuntu 12.10 to 13.04, and I fixed this by copying the /usr/bin/python to /path/to/my/env/bin/, and it worked just fine
cp /user/bin/python /path/to/my/env/bin/
or, there's a more elegant way to fix this(reference):
mkvirtualenv <existing virtualenv name>
_sre is a built in module, so there's no file to include for it, but it doesn't have a MAXREPEAT attribute in Python 2.7.3:
>>> import _sre
>>> _sre
<module '_sre' (built-in)>
>>> _sre.MAXREPEAT
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: 'module' object has no attribute 'MAXREPEAT'
My best guess is that your frozen copy somehow has the standard library .py modules from Python 2.7.4, but the compiled Python interpreter from 2.7.3 or an earlier version. I see you're working from /usr/local - maybe it's picking up an older version from /usr.
If all else fails, I got things running using this: http://www.kiwisoft.co.uk/blog/2014/08/17/fixed-importerror-cannot-import-name-maxrepeat
I had the same problem recently. Setting LD_LIBRARY_PATH=
solved the problem.
I was using cx_freeze 4.3.2 on my win 8 machine and it was always showing ImportError: cannot import name MAXREPEAT with cx Freeze if I ever tried to freeze a non built-in module, and once I downloaded version 4.3.1, it works, I'm able to freeze my all python 3.3 programs without any problem now.
I was having similar issues on windows 8 - was just a PYTHONPATH issue. check that PYTHONPATH exists by typing the following into a python session:
import os
os.environ['PYTHONPATH'].split(os.pathsep)
if you get an error set your PYTHONPATH using this approach..
How to add to the pythonpath in windows 7?

I've started playing around with pygame and pythonw recently, however whenever I attempt to import a majority of modules pythonw either imports incomplete modules or fails to import entirely.
All of the importing errors involve a Expected in: Flat Namespace
error with one of the many .so files in my conda3 python directory, which led me to believe that they were being loaded incorrectly by python or that they were broken; however, the modules all imported correctly in regular python.
I've ruled out the pythonw being located in a directory with nonexistent modules, as running sys.path in python and pythonw returns the same list.
Example of error, with the default-loaded help() command in Python(w) idle:
>>> help()

Expected in: flat namespace
Referenced from: /anaconda3/lib/python3.6/lib-dynload/_posixsubprocess.cpython-36m-darwin.so
In the case of pygame, modules such as font are loaded incorrectly and instead replaced with pygame.MissingModule objects
>>> pygame
<module 'pygame' from '/anaconda3/lib/python3.6/site-packages/pygame/__init__.py'>
>>> pygame.font
<pygame.MissingModule object at 0x10e8b5400>
>>>
Does anyone have any idea what is happening here? Any help would be greatly appreciated!

I have multiple Python versions installed with pyenv on Ubuntu 16.04. I create virtual environments to work with projects using different versions with pipenv. However, for Python 3.5.x only I get errors like this when I try to edit a file with Vim 8 (installed via the PPA) in an activated virtualenv:
"test.py" 49L, 1434C
Error detected while processing function jedi#init_python[4]..<SNR>48_init_python[27]..jedi#setup_python_imports:

The issue seems to affect all python related Vim plugins. With other Python versions (e.g. 3.6.x, 3.7.x) this does not occur. What may be causing this issue?
Update: It seems that when I run Vim inside a 3.5.x virtualenv, the Vim's interpreter's sys.path gets updated somehow. For example, this is the output of :py3 import sys; print(sys.path) inside a 3.6.0 virtualenv:
['/usr/lib/python35.zip', '/usr/lib/python3.5', '/usr/lib/python3.5/plat-x86_64-linux-gnu', '/usr/lib/python3.5/lib-dynload', '/usr/local/lib/python3.5
/dist-packages', '/usr/lib/python3/dist-packages', '_vim_path_']
And this is for 3.5.3:

The issue can be reproduced in a ubuntu:16.04 docker container.
Debian Bug report logs - #852163: python3.5-minimal wont configure demonstrates that this error (for Python 3.5 and Python 3.6) is due to another incompatible installation of Python in /usr/local.
Some further digging with another user in #debian who was experiencing this
problem indicated that it was related to a locally installed
/usr/local/bin/python3.5. The stdlib in /usr/lib/python3.5 is picked up by the
/usr/local/bin/python3.5 but is not compatible with it, resulting in the
stacktrace shown.
Removing /usr/local/bin/python3* and all traces of that installation from
/usr/local/lib (plus other associated tools) solved this problem for the user
I was helping in #debian.

The problem is caused by the system installed python, which conflicts with personally installed python.
It could be the case that other python versions are interfering here. Do you have a PYTHONPATH set?
echo $PYTHONPATH
If it is set you could try to unset it. It's usually not needed when using virtual environments.
Try running python with sudo. I think the python which comes with OS needs to run with admin privilege.
I want to use regex package without installation (neither using pip nor python setup.py install)
For that, I have downloaded the package and kept in the same directory of the file where I am importing regex. The code is given below
import sys
import os
currentdirectory = os.getcwd()
sys.path.append(currentdirectory+"/packages/regex/Python2/")
from regex import *
I am getting following error as _regex extension module is not created.
Traceback (most recent call last):

How do I create _regex extension module that can be locally used?
Also, can I create _regex extension module file such that I can use the same file in different machines without creating again?
I have a C++ program, which has an embedded python 3.4.3+. I am attempting to run a script which uses a module named requests, this module depends on socket, but the embedded interpreter in unable to import _socket

I also know that _socket.pyd is located in DLLs in the python install location, however I don't know if it should also be in another location.
How can I make my program's embedded interpreter find the _socket module?
Have you tried opening the python terminal and load the socket library? (i.e. "import socket")
I see you are using MSVC, meaning you are using windows. To open the python terminal open a command prompt and just type python and press enter. You are now in the python terminal.
If that does not work, then there is a problem with the python installation.
Another thing, if you installed python using a proper python installer well the problem will most probably not be due to a bad install.
Best regards.
try adding the path to the module to python:
sys.path.append(path/to/module)
this should allow you to import the module.
This happened to me while debugging my c++ application in VS 2019.
Because Python is missing the debug compiled files: _d.dll _d.pyd *d_.lib
Solution:
download the source code and build your debug version
Debug Version Build
copy from .\PCbuild\amd64 to your python directory
*._d.dll ==> .\%PYTHONHOME%\
*._d.pyd ==> .\%PYTHONHOME%\DLLs
*._d.pdb ==> .\%PYTHONHOME%\DLLs
*._d.lib ==> .\%PYTHONHOME%\libs
Set environment variables %PYTHONHOME% and %PYTHONPATH%
Add the path to sys.path
PyObject* sys_path = PySys_GetObject("path");
retVal = PyList_Append(sys_path, PyUnicode_FromString("C:\\Python38_64\\DLLs"));
try debugging again ;-)
I'm running into an issue with cx_Freeze when running a frozen application (works fine unfrozen).
