I am building an python project with Eel, and I'm trying to package my program to an exe with PyInstaller as instructed in the documentation. However, I get the following error when I open the .exe:
Error

AttributeError: 'NoneType' object has no attribute 'write'
I tried to use auto py-to-exe instead of Pyinstaller, but I got the same error. Finally, I tried to package the Eello world example from the Eel documentation to see if it was my program that was the issue, but I still got the same error. I found a similiar problem in a github issue, but I fail to see what I should attach to --add-data.
I am running Python 3.10.8 and Eel 0.14.0. I've now tried python 3.8.9 and python 3.9.13 without luck.
Update
Upon further investigation, I discovered that the error only occours when I attach --noconsole at the end of my cmd python -m eel hello.py web --onefile --noconsole . However, I want my app to work without a visible console.
One of the libraries you are using is attempting to write to sys.stdout and sys.stderr, which are set to None when you run pyinstaller with --windowed option.
You need to explicitly set sys.stderr and sys.stdout in your programs code as early as possible to a writeable object like an open file or an io buffer.
for example:
import sys
outfile = open("logfile.txt", "wt")
sys.stderr = outfile
sys.stdout = outfile

I am using sounddevice in my project running on Ubuntu - When I build a single file using pyinstaller it is failing with (The code works well when running the source python file):
Traceback (most recent call last):

OSError: PortAudio library not found

Unfortunately I can't simply apt get install the required portaudio on the machine, so it needs to be included in the package. I have tried adding in the lib using:
--add-binary libportaudio.so:. --add-binary libportaudio.a:.
But this isn't working. I'm guessing I need to actually import the portaudio library into my python source - is that correct? Any pointers on how to do this?
I fixed this problem by editing:
versions/3.8.5/lib/python3.8/site-packages/_pyinstaller_hooks_contrib/hooks/stdhooks/hook-sounddevice.py
elif is_linux:
path = os.path.join(
sfp[0], "_sounddevice_data", "portaudio-binaries", "libportaudio.so"
)
versions/3.8.5/lib/python3.8/site-packages/sounddevice.py
elif _platform.system() == 'Linux':
_libname = 'libportaudio.so'
Then included the libportaudio.so in the pyinstaller build:
--add-binary _sounddevice_data/portaudio-binaries/libportaudio.so:./_sounddevice_data/portaudio-binaries/
Strange behavior in PyCharm (2021.2.1 Professional Edition) with Python 3.9 and numpy 1.21.2.
When I run my program with "Run" then it works as expected. But when I run it with "Debug" then the following error messages appears and the program stops:

Any hints what could be the cause?
It crashes immediately at the following line:
import matplotlib.pyplot as plt
And in numpy at this line:

__deprecated_attrs__["typeDict"] = (
core.numerictypes.typeDict, <--- CRASH HERE
"`np.typeDict` is a deprecated alias for `np.sctypeDict`."
)
The bug is documented here, it is related to PySide2, which is used by default by PyCharm for PyQt compatibility. The workaround (besides downgrading numpy) is to go to PyCharm's settings / "Build, Execution, Deployment" / "Python debugger", and there uncheck or change the value of the PyQt compatibility drop-down to something else than Auto or PySide2:
I am working on MacOS and I am trying to use PyInstaller to circulate a script to some non tech colleagues. The script is imaginatively called script_V1.py and runs fine.
Up to now, I have had issues with PANDAS and SCIPY but they seem to be resolved with with the command
pyinstaller --onefile --hidden-import pandas._libs.tslibs.timedeltas --hidden-import scipy._lib.messagestream script_V1.py
However, I am now getting a different error (I'll post the full error below)
RuntimeError: Python is not installed as a framework. The Mac OS X
backend will not be able to function correctly if Python is not

I have tried the solution in a similar question on Stack Exchange:
Installation Issue with matplotlib Python
But I think that is actually a different problem with import statements not working within the script itself. In my case if I run the script as a .py script it works fine. Anyway adding the suggested file did not alter the error message. Im new to this and seem to be really struggling with PyInstaller (more than with python itself) so any help much appreciated.
The full error message is (I've added line breaks for clarity)

So the way I got this to work in the end was to force Matplotlib to use WebAGG and also install the 'tornado' package (which is needed for some reason).
I think this got foobarred when I was doing some brew update stuff. Everytime my system python3 is called, it emits:
Error in sitecustomize; set PYTHONVERBOSE for traceback:
KeyError: 'PYTHONPATH'
This is particularly annoying because I use powerline in my terminal and powerline makes several calls to python each time I execute a command.
Calling Python3 with a the Verbose flag I get:
$ PYTHONVERBOSE=True python3
<multiple pages of python startup info...>

So the system Python3 is trying to load the Python2 version of sitecustomize? I suspect that's the problem. If so, what are my options for fixing this? brew unlink python3 && brew link python3 didn't help.
I'm not sure what the bytecode is stale for 'sitecustomize' comment python is making is about, but I've also removed the sitecustomize.pyc file, which didn't help.
I am having issues with the standard logging module. If I open a python2.7 shell and import logging everything works fine:
$ python

But if I open a python3.4 shell and import logging I get the following error:

I have no idea what the problem is and can't seem to find anyone else who has had the same issue.
logging module is by default there in Python 3 environment .No need to import it.
You seem to have installed a third party library called logging in your Python 3 environment, which is hiding the standard library version, and one of its files has a typo.
I stupidly created a file called logging.py to try out some log features. Then when trying the code below, it is effectively referring to itself and can't find the debug method.
import logging
logging.debug("Debug message")
Changing my file name to logtest.py fixed the problem.
for me it was the previous install of a logging library under an older Python version.
pip3 uninstall logging
fixed it for me.
