Sounds like you might have downloaded the Kafka sources (labeled src) rather than the binaries

Download the binary link for the desired Kafka version from here: https://kafka.apache.org/downloads

Download the correct binary package instead (the one without src in the name)

check the space between directories where you have downloaded your kafka. Remove space and run again

Make sure you have download the binaries. If youre sure you have the binary then in your terminal navigate to the directory kafka is stored in and type "pwd" and check the working directory for a space.

For example..

On macos I was working in a directory called. "Mobile Dev". When I got the working directory with pwd it showed this.

/Users/chris/Desktop/Mobile Dev/kafka_2.13-3.9.0

changed to this

/Users/chris/Desktop/MobileDev/kafka_2.13-3.9.0

So then I renamed my directory from Mobile Dev to MobileDev and everything worked great after that.
