I have been playing with PyInstaller on Windows 7 (64 bit). I am currently using PyInstaller 3.1.1 with Python 2.7.6. I created an app that creates a simple PySide GUI and generated a dist folder with an executable with this command:

> C:\Python27\Scripts\pyinstaller.exe .\HelloWidget.spec

This is what the spec file looks like:

# -*- mode: python -*-

block_cipher = None


a = Analysis(['HelloWidget.py'],
             pathex=['C:\\Users\\spearsc\\Documents\\python_projects\\HelloWorldGui'],
             binaries=None,
             datas=[('.\\mainwindow.ui', '.')],
             hiddenimports=[],
             hookspath=[],
             runtime_hooks=[],
             excludes=[],
             win_no_prefer_redirects=False,
             win_private_assemblies=False,
             cipher=block_cipher)
pyz = PYZ(a.pure, a.zipped_data,
             cipher=block_cipher)
exe = EXE(pyz,
          a.scripts,
          exclude_binaries=True,
          name='HelloWidget',
          debug=False,
          strip=False,
          upx=True,
          console=True )
coll = COLLECT(exe,
               a.binaries,
               a.zipfiles,
               a.datas,
               strip=False,
               upx=True,
               name='HelloWidget')

I wanted to use a spec file, so the .ui file would be bundled along with everything else. However, when I run the executable, I get this error:

> .\HelloWidget.exe
Traceback (most recent call last):
  File "<string>", line 41, in <module>
  File "c:\users\spearsc\appdata\local\temp\pip-build-djws3k\pyinstaller\PyInstaller\loader\pyimod03_importers.py", line

WindowsError: [Error 2] The system cannot find the file specified.
pyi_rth_qt4plugins returned -1

What is confusing to me is that when I look in the dist folder, I see compiled PySide and Qt files:

Any thoughts? Can I not trust what I see in the dist folder?

5/25/16:

Well, this is interesting. I put a print statement in the _get_win32_short_name function.

def _get_win32_short_name(s):
    """ Returns short name """
    print s
    buf_size = MAX_PATH
    for i in range(2):
        buf = create_unicode_buffer(u('\0') * (buf_size + 1))
        r = GetShortPathNameW(u(s), buf, buf_size)
        if r == 0:
            raise WinError()
        if r < buf_size:
            if PY_2:
                return buf.value.encode(sys.getfilesystemencoding())
            return buf.value
        buf_size = r
    raise WinError()

Here is the result I got back after I built a new executable.

WindowsError: [Error 2] The system cannot find the file specified.

The directory does not exist. Any ideas on how to get around that?

The trick is to add an empty PySide folder in the dist folder.

    Directory: C:\Users\spearsc\Documents\python_projects\HelloWorldGui\dist\HelloWidget

After I did that I ran the executable and got an import error for PySide.QtXml, so I generated a new spec file and modified it.

# -*- mode: python -*-

block_cipher = None


a = Analysis(['HelloWidget.py'],
             pathex=['C:\\Users\\spearsc\\Documents\\python_projects\\HelloWorldGui'],
             binaries=None,
             datas=[('.\mainwindow.ui', '.')],
             hiddenimports=['PySide.QtXml'],
             hookspath=[],
             runtime_hooks=[],
             excludes=[],
             win_no_prefer_redirects=False,
             win_private_assemblies=False,
             cipher=block_cipher)
pyz = PYZ(a.pure, a.zipped_data,
             cipher=block_cipher)
exe = EXE(pyz,
          a.scripts,
          exclude_binaries=True,
          name='HelloWidget',
          debug=False,
          strip=False,
          upx=True,
          console=True )
coll = COLLECT(exe,
               a.binaries,
               a.zipfiles,
               a.datas,
               strip=False,
               upx=True,
               name='HelloWidget')

I then used the spec file to create the executable again. I added the empty PySide to the dist folder, and it worked!
