Python 2.7 尝试导入时出现httplib2无效语法错误

我正在尝试设置一个ApacheBeam管道，在运行代码时不断出现以下错误

看起来您正试图使用Python 2解释器中的Python 3模块（其中，

print

是一条语句，而不是一个普通函数）。

  for h, v in msg.items():
      print('%s:' % h, end=' ', file=self._fp)
      if isinstance(v, Header):
          print(v.encode(maxlinelen=self._maxheaderlen), file=self._fp)
      else:
          # Header's got lots of smarts, so use it.
          header = Header(v, maxlinelen=self._maxheaderlen, charset='utf-8',
                          header_name=h)
          print(header.encode(), file=self._fp)
  # A blank line always separates headers from body
  print(file=self._fp)
