Question

我在名为SymbolManager.py的文件中有以下类：

from qgis.core import *

class SimbolManager:
  def __init__(self):
    self.initSymbols()

  def initSymbols(self):
    self.symbolMap = {}
    props = {'color': '0,0,200'}
    self.symbolMap['SimpleVertex'] = QgsMarkerSymbolV2.createSimple(props)

    props = {'width': '1', 'color': '0,0,255'}
    self.symbolMap['SimpleLine'] = QgsLineSymbolV2.createSimple(props)

  def getSymbolRenderer(self, name):
    symb = self.symbolMap[name]
    if symb is not None:
      return QgsSingleSymbolRendererV2(symb)
    return None

从同一目录中的文件我尝试以这种方式导入SymbolManager：

from PyQt4 import QtCore, QtGui
from Ui_OsmNavigator import Ui_OsmNavigator

from PyQt4.QtCore import *
from PyQt4.QtGui import *
from qgis.core import *

import DbConnection

from SymbolManager import SymbolManager  // HERE IS THE PROBLEM

当我运行脚本时，从QGIS内部出现以下错误：

第28行，在从SymbolManager导入SymbolManager ImportError：无法导入名称SymbolManager

我做错了什么？

因为您的课程未被调用SymbolManager？

class SimbolManager: 
      ^^^^^^
