PyInstaller误差与PySide

Question

我一直在Windows 7 (64位)上玩PyInstaller。我目前在Python2.7.6中使用PyInstaller 3.1.1。我创建了一个应用程序，该应用程序创建了一个简单的PySide图形用户界面，并使用以下命令生成了一个带有可执行文件的dist文件夹：

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

这就是spec文件的样子：

# -*- 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')

我想使用一个规范文件，所以.ui文件将与其他文件捆绑在一起。但是，当我运行可执行文件时，会得到以下错误：

> .\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
 389, in load_module

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

令我困惑的是，当我查看dist文件夹时，我看到编译的PySide和Qt文件：

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

有什么想法吗？我可以不信任我在dist文件夹中看到的内容吗？

5/25/16：

嗯，这很有趣。我在_get_win32_short_name函数中放置了一个print语句。

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()

这是我在构建了一个新的可执行文件之后得到的结果。

目录不存在。有什么解决办法吗？

诀窍是在dist文件夹中添加一个空的PySide文件夹。

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

在这样做之后，我运行了可执行文件，并获得了PySide.QtXml的导入错误，所以我生成了一个新的规范文件并对其进行了修改。

# -*- 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')

然后，我再次使用spec文件创建可执行文件。我将空的PySide添加到dist文件夹中，它成功了！
