Why function blpsrv is 'undefined' after Datafeed Toolbox is installed

I have installed the trial version of Datafeed Toolbox, and it appears under 'ver' command. However when I try to run command blpsrc(...), the error

Undefined function or variable 'blpsrv'

is reported.

I use MacOs, and I checked the folder of Datafeed Toolbox which should contain the function, but I only find function blp there, nothing else is presented. Anyone can help me solve the problem? Thanks.
