difference between expo version and expo sdk version

Question

I am learning react native mobile development using expo. I am finding it difficult to understand the difference between expo and expo sdk. Can anyone please tell me the difference between these two commands provided below. The first command returns output as 6 whereas the second command returns output as 50.

expo --version
6.3.10

npm show expo version
50.0.4

Answer 1

expo --version is used to check the version of the Expo CLI installed globally on your system.

npm show expo version is project specific and checks the version of the Expo SDK in your current project directory.
