我正在从http://www.python.org/getit/运行 python 2.7.3 (python-2.7.3.amd64.msi)
我正在使用这些安装程序：http ://www.lfd.uci.edu/~gohlke/pythonlibs/
- PyQt-Py2.7-x64-gpl-4.9.6-1.exe
- PySide-1.1.2.win-amd64-py2.7.exe
- MySQL-python-1.2.4.win-amd64-py2.7.exe
我还尝试了来自以下位置的 pyqt 和 pyside 二进制文件：
- http://www.riverbankcomputing.com/software/pyqt/download
- http://qt-project.org/wiki/PySide_Binaries_Windows
我在以下 python 代码中收到错误“QSqlDatabase：未加载 QMYSQL 驱动程序”。我最好的猜测是上面的 pyside 和 pyqt 二进制安装程序没有构建 qt 以包含 QMYSQL？任何人都可以确认并且更重要的是，将我引导到构建了 QMYSQL 驱动程序的安装程序？我不准备尝试自己编译 qt 库。任何帮助表示赞赏。

self.model = QtSql.QSqlDatabase(self)

app = QtGui.QApplication(sys.argv)
if not createConnection():
sys.exit(1)
myapp = MyForm()
myapp.show()
sys.exit(app.exec_())
这是gui代码：
from PySide import QtCore, QtGui
class Ui_Dialog(object):
def setupUi(self, Dialog):
Dialog.setObjectName("Dialog")
Dialog.resize(400, 300)
self.tableView = QtGui.QTableView(Dialog)
self.tableView.setGeometry(QtCore.QRect(20, 20, 256, 192))
self.tableView.setObjectName("tableView")
self.retranslateUi(Dialog)
QtCore.QMetaObject.connectSlotsByName(Dialog)
def retranslateUi(self, Dialog):
Dialog.setWindowTitle(QtGui.QApplication.translate("Dialog", "Dialog", None, QtGui.QApplication.UnicodeUTF8))
