qwebview in pyside after packaged with pyinstaller goes wrong

Question

Here's my code

import sys
from PySide.QtCore import *
from PySide.QtGui import *
from PySide.QtWebKit import *

from encodings import *
from codecs import *

class BrowserWindow( QWidget ):
    def __init__( self, parent=None ):
        QWidget.__init__( self, parent )

        self.Setup()
        self.SetupEvent()

    def Setup( self ):
        self.setWindowTitle( u"Truease Speedy Browser" )

        self.addr_input = QLineEdit()
        self.addr_go = QPushButton( "GO" )

        self.addr_bar = QHBoxLayout()
        self.addr_bar.addWidget( self.addr_input )
        self.addr_bar.addWidget( self.addr_go )


        for attr in [

            QWebSettings.globalSettings().setAttribute( attr, True )

        self.web_view = QWebView()
        self.web_view.load( "http://www.baidu.com" )

        layout = QVBoxLayout()
        layout.addLayout( self.addr_bar )
        layout.addWidget( self.web_view )

        self.setLayout( layout )

    def SetupEvent( self ):
        self.connect(
            self.addr_input,
            SIGNAL("editingFinished()"),
            self,
            SLOT("Load()"),
            )
        self.connect(
            self.addr_go,
            SIGNAL("pressed()"),
            self,
            SLOT("Load()")
            )
        self.connect(
            self.web_view,
            SIGNAL("urlChanged(const QUrl&)"),
            self,

    def Load( self, *args, **kwargs ):
        url = self.GetCleanedURL()
        if url != self.CurrentURL():
            self.web_view.load( url )

    def SetURL( self, *args, **kwargs ):
        self.addr_input.setText( self.CurrentURL() )

    def GetCleanedURL( self ):
        url = self.addr_input.text().strip()
        if not url.startswith("http"):
            url = "http://" + url
        return url

    def CurrentURL( self ):
        url = self.web_view.url().toString()
        return url

def Main():
    app = QApplication( sys.argv )
    widget = BrowserWindow()
    widget.show()
    return app.exec_()


if __name__ == '__main__':
    sys.exit( Main() )

I works well when i using python browser.py. but it goes wrong after packaged with pyinstaller -w browser.py.

1. it doesn't load images
2. can only display correct text in utf-8

And this is the pyinstaller output:

Answer 1

I encountered this same problem. It is caused by PyInstaller using incorrect versions of ssleay32.dll and libeay32.dll.

To fix, download and install "Win32 OpenSSL v1.0.1e".

Then create a spec file for your PyInstaller project:

pyi-makespec browser.py

Open your spec file, named browser.spec, and below the a = Analysis(['browser.py']) line, add:

for d in range(len(a.binaries)):
    if a.binaries[d][0].lower() == 'ssleay32.dll':
        print a.binaries[d]
        a.binaries[d] = ('ssleay32.dll', 'C:\\\OpenSSL-Win32\\ssleay32.dll', 'BINARY')
    if a.binaries[d][0].lower() == 'libeay32.dll':
        print a.binaries[d]
        a.binaries[d] = ('libeay32.dll', 'C:\\OpenSSL-Win32\\libeay32.dll', 'BINARY')

This will tell PyInstaller to use the OpenSSL-Win32 dlls instead of the ones your Python installation is using.

When running the Python script, my Python installation preferred the DLLs in my system path to those installed by pyOpenSSL/egenix, but when bundling with PyInstaller, it seems to prefer the pyOpenSSL/egenix ones. This should fix that.
