Path issue

[maca]

I am trying to get started with zajal by following the README but I am facing this problem:

$ bin/zajal examples/hello-world.zj                                                                                                         21:56:52
An exception occurred running bin/zajal:

    no such file to load -- zajal (LoadError)

Backtrace:
