How To Fix ffjson: command not found in Ubuntu / Debian / Kali Linux / Raspbian

In Ubuntu ffjson is provided by ffjson package.

ffjson is:

ffjson generates static MarshalJSON and UnmarshalJSON functions for structures in Go. The generated functions reduce the reliance upon runtime reflection to do serialization and are generally 2 to 3 times faster. In cases where ffjson doesn’t understand a Type involved, it falls back to encoding/json, meaning it is a safe drop in replacement. By using ffjson your JSON serialization just gets faster with no additional code changes.

This package contains the ffjson executable.

To fix this problem, we can install more using the command below.

sudo apt-get -y install ffjson

This command might take some time to finish depending on your machine internet connection.

sudo apt -y install ffjson

sudo aptitude install ffjson
