python-nmap是一个python的库，python2.x使用的是python-nmap-0.1.4，使用过程中遇到一点问题。记录如下：
错误信息：
Traceback (most recent call last):

pickle.PicklingError: Can't pickle <function scan_progressive at 0x01C255B0>: it
's not found as nmap.nmap.scan_progressive
仔细追查，在pickle.py文件745行抛出了错误：
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "D:\opt\Python27\lib\site-packages\nmap\nmap.py", line 413, in scan
target=self.scan_progressive,
AttributeError: 'PortScannerAsync' object has no attribute 'scan_progressive'
然后又阅读nmap的源码nmap.py,终于发现在402行，方法scan_progressive被定义在scan方法内部，导致pickle失败。
解决方法：
将方法Scan_progressive定义到外面，并将nmap.py 413行从
target=scan_progressive,
改为
target=self.progressive,
修改后完整代码

您好，请问您在windows下如何安装的nmap，我这边有点问题，不知道您那边在不在
现在可以直接下载安装包进行安装
