Exception: Qt plugin directory '/plugins' does not exist! - PySide6 #7463

aaroncpascua · 2023-02-24T20:11:00Z

PyInstaller version 5.8.0

Python version 3.9.13

Platform: Windows (NA)

Installed python through python.org/downloads

I have not tried this on another platform.

I have uninstalled/reinstalled PySide6 6.4.2 and PyInstaller and have used the PyInstaller developer package.

I'm not much of a developer and saw that people were editing the ~\venv\Lib\site-packages\Pyinstaller\utils\hooks\Qt.py, but I can't seem to find that file anywhere? I also noticed that this person had a very similar problem, but their issue was a character encoding problem. I noticed that their path was an actual full path however. Here, my path is just '/plugins' and nothing else. I tried sifting through the stacktrace, but I can't make anything of it. The path also very much exists here ...\venv\Lib\site-pacakges\PySide6\plugins

Stacktrace / full error message

What is the output if you run the following snippet in your environment?

import PySide2
from PySide2 import QtCore

app = QtCore.QCoreApplication([])
info = QtCore.QLibraryInfo()
print("Package paths:", PySide2.__path__)
print("Prefix path:", info.location(QtCore.QLibraryInfo.PrefixPath))
print("Binaries path:", info.location(QtCore.QLibraryInfo.BinariesPath))
print("Plugins path:", info.location(QtCore.QLibraryInfo.PluginsPath))

Here's my output:

FYI, I decided to change my project to PySide6 just to upgrade in the meantime. I have adjusted your code snippet:

import PySide6
from PySide6 import QtCore

app = QtCore.QCoreApplication([])
info = QtCore.QLibraryInfo()
print("Package paths:", PySide6.__path__)
print("Prefix path:", info.path(QtCore.QLibraryInfo.PrefixPath))
print("Binaries path:", info.path(QtCore.QLibraryInfo.BinariesPath))
print("Plugins path:", info.path(QtCore.QLibraryInfo.PluginsPath))

And here's the output:

Package paths: ['...\\venv\\lib\\site-packages\\PySide6']
Prefix path:
Binaries path: /bin
Plugins path: /plugins

This looks like paths being incorrectly reported by your PySide installation...

How did you install PySide2/PySide6? Are these standard PyPI wheels (e.g., pip install pyside6), or something else?

I just used pip3 install pyside6

Hmm, how about this?

import PySide6
from PySide6 import QtCore

app = QtCore.QCoreApplication([])
info = QtCore.QLibraryInfo()
print("Package paths:", PySide6.__path__)
print("Prefix path:", info.path(QtCore.QLibraryInfo.PrefixPath))
print("Binaries path:", info.path(QtCore.QLibraryInfo.BinariesPath))
print("Library executables path:", info.path(QtCore.QLibraryInfo.LibraryExecutablesPath))
print("Plugins path:", info.path(QtCore.QLibraryInfo.PluginsPath))
print("")

# Check if PySide installed embedded qt.conf at run-time
embedded_qt_conf = QtCore.QFile(":/qt/etc/qt.conf")
if embedded_qt_conf.open(QtCore.QIODevice.ReadOnly):
    data = embedded_qt_conf.readAll()
    print("Embedded qt.conf data:", data)
else:
    print("No embedded qt.conf available!")

Is your PySide using embedded qt.conf at the run-time or not?

For the reference, the expected output when embedded qt.conf properly sets the paths is:

Package paths: ['C:\\Users\\Rok\\Development\\pyi-pyside6\\venv\\lib\\site-packages\\PySide6']

I'm running out of ideas, then, and cannot reproduce this - based on the above outputs I'd say that this is either a bug in PySide or an issue in your environment.

Is there anything special about the part of the path that you are not showing us (the ...)? Does it contain non-ASCII characters, or symbols in the directory names? Is the path located on a non-local drive, perhaps?

Do you get proper paths by the above snippet if you create a new virtual environment somewhere on the primary hard drive?

Yeah, I'm not sure what's happening. The ... is a OneDrive, so the string is like OneDrive - Company. What I find really weird is that it worked one my OneDrive before, I just moved it to my Desktop on the OneDrive because my previous path was starting to get too long for some file names. But when I moved it, there was no problem.

I decided to truly use my local C: drive and it works. So something weird is going on there that I don't understand. I'll close the forum, but unfortunately could never find a true answer.
