Error while trying to configure ProxySQL administration tools

I’m trying to configure the ProxySQL admin tools and I’m having trouble running the command: proxysql-login-file --in data.cnf --out login-file.cnf - password = ${passwd}

displaying the following error: ERROR (line: 725): Unable to find executable v1.1.1 + OpenSSL in path.
- Make sure OpenSSL v1.1.1 or higher is installed and in the path.

Note: I have OpenSSL installed and I don’t see any impediment to running the command.

The tutorial I’m following: The ProxySQL Admin Tool with ProxySQL v2
