我正在尝试通过 pip 安装 pybloomfiltermmap 版本 0.3.14（它位于虚拟机 ubuntu 16.04 上）
sudo pip install pybloomfiltermmap==0.3.14
但我收到一个错误，但我不知道为什么或者如何解决它：
rptk99@ubuntu:~/w3af$ sudo pip install pybloomfiltermmap==0.3.14

rptk99@ubuntu:~/w3af$
我该如何解决这个问题？
答案1
/usr/bin/ld: cannot find -lcrypto
-lcrypto方法libcrypto.so
解决方案：
sudo apt-get install libssl-dev
答案2
使用以下方式安装 pybloomfiltermmap 0.3.14-0.1.debLaunchpad 上的这个包。
或者
sudo apt-get install build-essential libssl-dev libffi-dev python-dev
pip install pybloomfiltermmap
