pyenv和python 2.7.12导入cElementTree失败

Question

我尝试导入cElementTree，但是失败。

Python 2.7.12 (default, Jul 19 2018, 15:12:44)
[GCC 4.8.4] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import xml.etree.cElementTree
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/tomcat/.pyenv/versions/2.7.12/lib/python2.7/xml/etree/cElementTree.py", line 3, in <module>
    from _elementtree import *
ImportError: No module named _elementtree

看起来pyenv环境中不存在_elementtree模块（C lang模块？）。我该怎么办？

Answer 1

我已经从pyenv重新安装了python 2.7.12。问题已解决。
