I want to create a portable PyQt5.2.1 package [Question]
-
very good thread, thanks
i have some progress, but yet it does not work and give some error:
first error, (This application failed to start because it could not find or load the Qt platform plugin “windows”.
Reinstalling the application may fix this problem.), is fixed with this way:
in code of launcher i got the path of this file (here Deployment folder) as dynamically and send it to QApplication.addLibraryPath(path)but a new error occured: (i had it before, if you remember i looked for QML_IMPORT_PATH env for that but i reach to this point)
QQmlApplicationEngine failed to load component
file:///C:/Users/Madoodia/Desktop/Deployment/test.qml:2 module "QtQuick.Controls" is not installed
file:///C:/Users/Madoodia/Desktop/Deployment/test.qml:1 module "QtQuick" is not installed
because i have this two line in test.qml file:
import QtQuick 2.0
import QtQuick.Controls 1.0what is this error?
i put all folders of C:\Qt\Qt5.2.1\5.2.1\msvc2012_64\qml beside my app
why give error?i should tell that when i run test.qml it runs, and window is appeared.
(also, i have QtHidden yet)thanks for reply in advanced

Have you talked to people at the PyQt mailing list?
I am only guessing here: Maybe it's because you are not launching an .exe file. You are loading a Python script file, so maybe Qt is searching in the folder where python.exe is.
-
Yes, you are right, and i have post on riverbank's mailing list for pyqt, but anybody does not answer me.
thanks for your guessing
i put QtQuick and QtQuick.2 folder and platform folder beside python.exe and proram works.but i want to know that how can i tell program that this files is beside you.and first search your folder then if it is not here go to Python27 folder.???
if help me about paths i really own to you
-
At the beginning of mainLauncher.py, what does os.getcwd() return? What happens if you call os.chdir() to go to the deployment folder, before you start calling Qt stuff?
-
[quote author="madoodia" date="1398588817"]os.getcwd() >>> C:\Users\Madoodia\Desktop\Deployment
you mean this :
path = os.getcwd()
os.chdir(path)
?nothing
i'm in deployment folder[/quote]Yes, that's what I meant. It didn't work though...Ok, try playing around with QQmlEngine::addImportPath() or QQmlEngine::addPluginPath() (see http://qt-project.org/doc/qt-5/qqmlengine.html) -- these are like QApplication::addLibraryPath().
If you used a QQuickView, you can get the engine by calling QQuickView::engine()

hey there
yes
i work with this and i got the good results.
and i find the way.not Portable PyQt5 but i can find more thing that i will document all off that in these days.
but a new problem occurs.
my program works fine in my labtop.
i switch to pyinstaller to make it executable and i had infinite problems.
i solved all off them too.
but there is a big problem that i could not solve it yet.
i changed program to one exe file and it works in my labtop fine.
but when i transform it to another clean pc or clean VM it does not work and give this error (again):
This application failed to start because it could not find or load the Qt platform plugin “windows”.
Reinstalling the application may fix this problem.
:)
this error want to kill me...
any feedback welcome.
thanks again -
Load your .exe with Dependency Walker (http://www.dependencywalker.com/ ) and choose Profile -> Start Profiling.
That will show you where it's searching for DLLs.
[quote]i switch to pyinstaller to make it executable[/quote]The search paths for the .exe file might be different from the .py file

ok
i did that an find that all Loading is between two same commands,for example one line of LoadLibraryW ... some other lines...again LoadLibraryWand this is result:
LoadLibraryW("C:\Users\vm1\AppData\Local\Temp_MEI26242\qt5_plugins\platforms\qwindows.dll") called from "QT5CORE.DLL" at address 0x00000000600C85EF.

LoadLibraryW("C:\Users\vm1\AppData\Local\Temp_MEI26242\qt5_plugins\platforms\qwindows.dll") returned NULL. Error: The specified module could not be found (126).
what do you find from this?
the bold snippet in dependecy graph has red color.
look likes load successfully but... -
and this is in my labtop that run exe file completely:

i find this 3 files in windows/system32
WINMM.DLL
OLEAUT32.DLL
WINMMBASE.DLL
that i think should be shipped with exe file.and this to is shipped with file
QWINDOWS.DLL
LIBEGL.DLLand i think it can't use it because it don't have permission to access to them.
:(
