When I reach To “Bundle Install” Then This Appeares An error occurred while installing xorcist (1.1.2), and Bundler cannot continue. In Gemfile: xorcist What Will I do now

when i use this comand sudo apt install xorcist then it shows this Reading package lists... Done Building dependency tree Reading state information... Done E: Unable to locate package xorcist

Try to run sudo apt update and then again sudo apt install xorcist

similar error continues even after running this comand sudo apt update then sudo apt install xorcist

hi Gaurav; the xorcist gem does not need any external dependencies, which would usually be helped by installing packages through the OS like Daniela said. Rather, there seems to be a more general issue installing gems (lack of space, permissions, etc). Can you show more of the error message when it happens?
