I can't seem to upgrade deno on macOS 10.14.6 and now deno --verison shows -bash: deno: command not found - now ev en 1.0.5 is gone.

What is the alternative way to install deno 1.22.1 ?

[thomscoder]

you could either try building it from source or installing it using MacPorts.
MacPorts installation
Deno installation

I upgraded it with Homebrew in Monterey and worked fine.
Try one of those two methods

My homebrew won't seem to update because Im on Mojave.
Anyway, I installed it via curl -fsSL https://deno.land/install.sh | sh
Thanks
