swig error in ubuntu 16.04

For some reason **swig** on my computer is not configured correctly. It gives this output on checking version: $ swig --version swig: error while loading shared libraries: libpcre.so.1: cannot open shared object file: No such file or directory whereas on reinstalling it the following output is generated: piyush@piyush-HP:~/test$ sudo apt-get install swig [sudo] password for piyush: Reading package lists... Done Building dependency tree Reading state information... Done swig is already the newest version (3.0.8-0ubuntu3). 0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded. any suggestions for how to fix it? thanks.
