导入错误:没有名为元素树的模块.元素树

Question

我正在运行python 2.7，并且正在从其他开发人员那里获取一个项目，所以我只是尝试对其进行编译并收到导入错误，因为旧开发人员正在使用"导入元素树。ElementTree as ET"，所以我正在四处走动，用"import xml.etree.ElementTree as ET"替换该代码

但是现在遇到了这个仍然无法编译的文件。以下是回溯：

C:UsersDanielDocumentsTime clocksourceTimeClock>python timeclock.py
Traceback (most recent call last):
  File "timeclock.py", line 30, in <module>
    from CheckHoursDialog import CheckHoursDialog
  File "C:UsersDanielDocumentsTime clocksourceTimeClockCheckHoursDi
alog.py", line 11, in <module>
    from StudentEarningReport import StudentEarningReport
  File "C:UsersDanielDocumentsTime clocksourceTimeClockStudentEarni
ngReport.py", line 10, in <module>
    import elementtree.ElementTree as ET
ImportError: No module named elementtree.ElementTree

谁能指出我正确的方向？

这是文件的前 40 行。

问题是你已经修复了StudentEarningReportPanel.py，但你正在导入StudentEarningReport.py，你还没有修复。
