Afer execute the installer in Ubuntu 17.10 the command is not found

[mrsarm]

After execute the installer as explained in the README file, when I execute the command, I get:

$ jsonv
zsh: command not found: jsonv

Even restarting the command line I get the same. And looking if something was installed, I realized the command never was installed:

$ sudo find / -name jsonv

The command above doesn't get any result.
