Describe the bug
I executed the command:

go get -u github.com/apache/pulsar/pulsar-client-go/pulsar

Output:

@fananchong seems like a connectivity issue. did you try again?

[fananchong]

I try again, now this issue is pass. But have a new issue:

You need to install pulsar c++ client package. Go client is a wrapper on top of c++ client https://pulsar.apache.org/docs/latest/clients/Cpp/

@fananchong hello , now pulsar-client-go use the package management method of go mod, you first need to build pulsar-client-cpp, then you can use:

go mod tidy

to get the required dependencies without having to get it separately.

[fananchong]

I follow https://github.com/apache/pulsar/issues/3883#issuecomment-475634546 , execute like：

cd pulsar-client-cpp/pkg/rpm/
./docker-build-rpm.sh
cd RPMS/x86_64/
sudo rpm -ivh  apache-pulsar-client-2.4.0-1.x86_64.rpm
sudo rpm -ivh  apache-pulsar-client-devel-2.4.0-1.x86_64.rpm

now build pass

[fananchong]

have 1 new issue:

[fananchong@host-192-168-23-57 pulsar-client-go]$ ./bin/consumer
./bin/consumer: error while loading shared libraries: libpulsar.so.2.4.0-SNAPSHOT: cannot open shared object file: No such file or directory

I execute sudo ldconfig ， now it's working.
