I got this error before. I solved as below: 1: check if the current proto buf is 2.4.1, if not, uninstall it and install the 2.4.1 version
2: "error while loading shared libraries: libprotobuf.so.7: cannot open shared object file: No such file or directory" This is a known issue for Linux, and is caused by a stale cache of libraries. Run ldconfig and try again.
