导入错误：没有名为elementtree.ElementTree的模块

Question

我正在使用 Python 2.7，并且接手了一个其他开发者的项目。我只是想让它能正常编译，但遇到了导入错误，因为之前的开发者使用了 "import elementtree.ElementTree as ET"。所以我正在把这段代码替换成 "import xml.etree.ElementTree as ET"。

但是现在我遇到了一个文件，还是无法编译。以下是错误追踪信息：

C:\Users\Daniel\Documents\Time clock\source\TimeClock>python timeclock.py
Traceback (most recent call last):
  File "timeclock.py", line 30, in <module>
    from CheckHoursDialog import CheckHoursDialog
  File "C:\Users\Daniel\Documents\Time clock\source\TimeClock\CheckHoursDi
alog.py", line 11, in <module>
    from StudentEarningReport import StudentEarningReport
  File "C:\Users\Daniel\Documents\Time clock\source\TimeClock\StudentEarni
ngReport.py", line 10, in <module>
    import elementtree.ElementTree as ET
ImportError: No module named elementtree.ElementTree

有没有人能给我一些建议？

这是文件的前40行内容。

        self.SetupScrolling(scrollToTop=False)

    def __init__(self, parent, node):
        assert ET.iselement(node)
        #~ ET.dump(node)
        self.Elem = node

问题在于你已经修复了 StudentEarningReportPanel.py 这个文件，但你导入的 StudentEarningReport.py 文件还没有修复。
