In Debian Error: "command 'gcc' failed with exit status 1" (pip install)

Hello.
My have a goal, install pocketsphinx in python3 (3.7.5) or python3.8 (3.8.1).
When I try install (in python3) module pocketsphinx, I can see more problem. The last, what I can't solve, this is problem

• What's i trying:
  sudo apt-get install python3-dev
sudo apt-get install libevent-dev
  and of course sudo apt update
  (I don't know, What is the difference between apt and apt get?)

• Short text error:
