【问题描述】：
所以我正在努力通过 Jenkins 和 Ansible 进行自动化的分段部署。其中一部分是使用来自 ansible 的名为 ec2.py 的脚本，以便动态检索要部署到的匹配服务器列表。
SSH 进入 Jenkins 服务器并从 jenkins 用户运行脚本，脚本按预期运行。但是，从 jenkins 中运行脚本会导致以下错误：
ERROR: Inventory script (ec2/ec2.py) had an execution error: Traceback (most recent call last):

File "/usr/lib/python2.7/xml/sax/__init__.py", line 93, in make_parser
raise SAXReaderNotAvailable("No parsers found", None)
xml.sax._exceptions.SAXReaderNotAvailable: No parsers found
我对python不太了解，所以不知道如何进一步调试这个问题。
