Switch to inspect mode. - WIndows 10

问题

i got a prompt "Switch to inspect mode." when i do

rails c

it shows

    Loading development environment (Rails 6.0.3.4)
    Switch to inspect mode.

and I can't do anything only type "exit" to exit this console but I'd like to check last post in my website by typing

@post = Post.last

when i type irb it shows me the same.

ruby 2.7.2p137 (2020-10-01 revision 5445e04352) [x64-mingw32] git-bash I don't know what to do, I've tried to find a solution but futilely. Am I supposed to install linux to learn how to program in ruby on rails? XDD

edit: when i Type: @post = Post.last it shows

Post Load (0.4ms)  SELECT "posts".* FROM "posts" ORDER BY "posts"."id" DESC LIMIT ?  [["LIMIT", 1]]

Maybe IRB bug!
