Answer 2

I use dvm (an alternative to node's nvm) to have various deno versions installed (for aleph.js). One can easily switch the version using dvm use VERSION command.

dvm use 1.8.2

upgrade/downgrade :

deno upgrade --version 2.0.0

after upgrading you might need to reload the lock cache with --write-lock param

or manually remove them rm deno.lock

for monorepos find . -name "deno.lock" -type f -delete
