    ERROR: Command errored out with exit status 1: python setup.py egg_info Check the logs for full command output.
    解决方法： pip install cython
    使用：

    1. from pybloomfilter import BloomFilter
    3. # 创建bloom并记录在内存中
    4. f = BloomFilter(10000, 0.0001, 'aaaa.bloom')
    5. f = BloomFilter(capacity=10000, error_rate=0.0001, filename='aaaa.bloom')
    7. # 打开bloom
    8. f = BloomFilter.open('XXXX.bloom')
    9. # 添加一个
    10. f.add('yyy')
    12. # 添加很多
    13. # f.update(iterable)
    14. f.update(["20", "21", "22"])
    16. # 删除所有
    17. f.clear_all()
    19. # 复制并另起名为zzz.bloom
    20. f.copy('zzz.bloom')
    22. # 与nmap文件同步
    23. f.sync()

  1. windows环境下
    pip install pybloom-live
    链接： https://github.com/joseph-fox/python-bloomfilter
    使用： ```python from pybloom_live import BloomFilter

创建bloom

b = BloomFilter(100000, 0.00001) b.tofile(open(‘xx.bloom’), ‘wb’)

添加

b = BloomFilter.fromfile(open(‘xx.bloom’), ‘rb’) b.add(‘yyy’) b.tofile(open(‘xx.bloom’), ‘wb’) # 必须要写进去 ```
