You would run a query like this. Gotta put in the username you're looking for
Sherlock is a command line program. Since PyCharm is an IDE, you have to tell it what command line options you want to use. The message you are giving is because you are running Sherlock without giving it any users to search for.
Here is a StackOverflow entry talking about how to add command line options. I don't use PyCharm, so I am not sure if this works for your specific version. But, this is what is happening.

I've try this kind of format but it doesn't work and then I got error message
@monraPH
Before you run Sherlock, you have to install the all the modules that are required by running this:
$ cd sherlock
$ pip3 install -r requirements.txt
This issue appears to be an environmental issue rather than a problem with Sherlock itself. It also has been hanging out for some time. So, I am closing it out now to remove the clutter.
