How to downgrade Deno

Question

Using Aleph with Deno found a bug, with the incompatible versions and I need to downgrade. How I can downgrade the deno version from 1.8.1 to 1.6.3 without uninstalling it?

Answer 1

You can use deno upgrade command with specified version for upgrade or downgrade the deno.

deno upgrade --version 1.6.3

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
