Thank you for advice!
But I did not get along well even if I did it.
I do version management in nodebrew, but do you put it?
I want to know the version of other packages, too if possible.
$ node -v
v11.1.0
$expo init my-new-project
-bash: expo: command not found
npm WARN registry Using stale data from https://registry.npmjs.org/ because the host is inaccessible -- are you offline?
npm WARN registry Using stale package data from https://registry.npmjs.org/ due to a request error during revalidation.
I could not create a project even if I installed it again.
Such an instruction came out when I hit a command, does not it need me to care?
