maya控制台中的IndentationError但找不到任何要修复的缩进错误

Question

我正在制作一个索具工具/遵循Maya中的教程，由于某种原因我收到了意外的缩进错误。我经历了多次用空格或标签替换所有空白区域都无济于事。

import os

try:
    riggingToolRoot = os.environ["RIGGING_TOOL_ROOT"]
except:
    print "RIGGING_TOOL_ROOT environment variable not correctly configured"
else:
    import sys
    print riggingToolRoot
    path = riggingToolRoot + "/Modules"

    if not path in sys.path:
        sys.path.append(path)

    import System.blueprint_UI as blueprint_UI
    reload(blueprint_UI)

    UI = blueprint_UI.Blueprint_UI()

显然“将System.blueprint_UI导入为blueprint_UI”是违规行为 line，它只在blueprint_UI.py的最新更改后标记。如果有任何用处的话，我也包含了代码。

import maya.cmds as cmds
import System.utils as utils
reload(utils)

class Blueprint_UI:
    def __init__(self):
        # Store UI elements in a dictionary.
        self.UIElements = {}

        if cmds.window("blueprint_UI_window", exists=True):
            cmds.deleteUI("blueprint_UI_window")

        windowWidth = 400
        windowHeight = 598

        self.UIElements["window"] = cmds.window("blueprint_UI_window", width=windowWidth, height=windowHeight, title="Blueprint Module UI", sizeable=False)

        self.UIElements["topLevelColumn"] = cmds.columnLayout(adjustableColumn=True, columnAlign="center")

        # Setup tabs
        tabHeight = 500
        self.UIElements["tabs"] = cmds.tabLayout(height=tabHeight, innerMarginWidth=5, innerMarginHeight=5)

        tabWidth = cmds.tabLayout(self.UIElements["tabs"], q=True, width=True)
        self.scrollWidth = tabWidth - 40

        self.initialiseModuleTab(tabHeight,tabWidth)

        cmds.tabLayout(self.UIElements["tabs"], edit=True, tabLabelIndex=([1, "Modules"]))


        # Display window
        cmds.showWindow( self.UIElements["window"] )

    def initialiseModuleTab(self, tabHeight, tabWidth):
        scrollHeight = tabHeight # temp value

        self.UIElements["moduleColumn"] = cmds.columnLayout(adj=True, rs=3)

        self.UIElements["moduleFrameLayout"] = cmds.frameLayout(height=scrollHeight, collapsable=False, borderVisible=False, labelVisible=False)

        self.UIElements["moduleList_Scroll"] = cmds.scrollLayout(hst=0)

        self.UIElements["moduleList_Column"] = cmds.columnLayout(columnWidth = self.scrollWidth, adj=True, rs=2)

        # First separator
        cmds.separator()

        for module in utils.findAllModules("Modules/Blueprint"):
            print module
