Ok so I found the origin of the issue and a workaround. Moving manually the PyQt5Core.dll file into |

That's not correct, CI build for 5.12.3 crashes with exactly this error. |
|
@Overdrivr Sure, I actually mean that. |
|
Ah yes sorry, misread your message. Ok so we know where to look around for changes. |

Hey! I'm getting this exact error too. I tried adding PyQt5/Qt/bin path, tried adding Qt5core.dll to added data and added binary also in pyinstaller. But still same error |

Here is the new function def find_qt():
import os
path = os.environ['PATH']
dll_dir = os.path.dirname(__file__) + '\\Qt\\bin'
if os.path.isfile(dll_dir + '\\Qt5Core.dll'):
path = dll_dir + ';' + path
os.environ['PATH'] = path
else:
for dll_dir in path.split(';'):
if os.path.isfile(dll_dir + '\\Qt5Core.dll'):
break
else:
raise ImportError("unable to find Qt5Core.dll on PATH")
try:
os.add_dll_directory(dll_dir)
except AttributeError:
pass

This allows us to properly use color emojis on Linux and we don't need to add libQt5MultimediaGstTools anymore. We include a workaround to make PyQt5 5.12.3 work with PyInstaller, otherwise it would fail to start saying it can't find QtCore.dll. See pyinstaller/pyinstaller#4293 We also remove an unneeded copy of the Qt binaries.

Found same issue for PyQt 5.13.0 (via pip) (Downgrading to 5.12.2 also fixed the problem) |
See pyinstaller/pyinstaller#4293 and gridsync/gridsync@0abf8e7 (cherry picked from commit e58aa9c)
Can confirm this worked for me also |
Thank u sooooo much, ur point really help me out |
|
Would anyone be willing to fix this for PyQt5 5.12.3? It's a bit annoying to have to use the manual workaround described above for every single deploy. |
|
@matthewgdv I don't know much about PyInstaller, just some ideas. The first step of modifying os.environ['PATH'] = sys._MEIPASS + os.pathsep + os.environ['PATH']And does anyone know where the copy functions of |
If fixed, this will probably given in a new release i think. As this isn't version specific, as i said, 5.13.0 is also affected. I think all > 5.12.2 are. |

After applied the patch of I will test the version of PyQt 5.12.3 (Qt 5.12.4). Update: It seems that the Can you help me test if this patch is a generic solution? |
Still, have problem with or without patch |
|
@Duskhorizon What is the error message? |
Doesn't work for me either |
|
Manually added the following to my spec file and it works after that. Note this needs to be modified to the following for regular pyinstaller (non-developmental build): |
This worked perfectly, thank you so so much!
(Address adjusted based on where PyQt5 ins installed) |
|
@sz2723 Thanks! It works for me. I've wrote it in this way for my project: from pathlib import Path
import os
import PyQt5
opts = [ ...
f"--add-data={Path(PyQt5.__file__).parent}/Qt/bin{os.pathsep}PyQt5/Qt/bin"
] |

This is fixed now as of 47bd7f1. |

Hello, I'm getting exactly the same error as: Just installed via PIP today on Windows. |
|
I upgraded my PyQt5 to 5.13.1 and it's fixed. e.g pip install PyQt5 -- upgrade |
This worked after excruciating debugging. |
At least I hope so... When I bumped PyQt5 to 5.15.4 I got this: ``` 15839 INFO: Appending 'datas' from .spec Unable to find "c:\python39\lib\site-packages\PyQt5\Qt\bin\*" when adding binary and data files. ``` The code I'm removing here it is from: pyinstaller/pyinstaller#4293 (comment) PyQt5 python packaging changed a lot between 5.15.2 and 5.15.3.
Hi folks,
I'm packaging another PyQt5 application, and facing an issue at launch time:
What's weird is that the PyQt5 DLL ARE in the install folder, see below:
I thought that the base directory of the EXE file would at least be in the PATH, yet pyinstaller's bootloader can't find this DLL. Any idea on how to debug this ?
I'm puzzled because I recently packaged a similar PyQt5 app without problem.
