如何使用 jira-python 设置 fixVersions 字段

我正在尝试使用 jira-python 模块（http://jira-python.readthedocs.org/en/latest/）更新现有的 JIRA。具体来说，我正在尝试设置问题的fixesVersion 列表。我已经尝试了一段时间但没有运气。我缺少什么？

issue = jira.issue('DUC-391')
issue_dict = { 'fixVersions' : [{'id': '10115'}] }
issue.update(fields=issue_dict)

返回的堆栈跟踪：

Traceback (most recent call last):
  File "post-commit-jira.py", line 35, in <module>
    issue.update(fields=issue_dict)
  File "/Library/Python/2.6/site-packages/jira/resources.py", line 193, in update
    super(Issue, self).update(**data)
  File "/Library/Python/2.6/site-packages/jira/resources.py", line 72, in update
    raise_on_error(r)
  File "/Library/Python/2.6/site-packages/jira/exceptions.py", line 29, in raise_on_error
    error = errorMessages[0]

issue_dict = { 'fixVersions' : [{'add': {'name': 'Name of the version 10115'}}] }
