@axetroy can you replace code below // ensure script that is being installed exists with call to deno fetch?

Can you explain why you need to use deno fetch? I will be appreciated

[bartlomieju]

Sure: right now it downloads remote file using fetch or looks for local file using stat - this step is validating that file you're trying to install exists. It's fine, but a bit non-sense because downloaded file is discarded. We can just use deno fetch to do the same job (validating that file exists) as well as to download and compile deps so on first run it will just run skipping download/compilation step then.

@bardiarastin makes sense. I will finish it later.

@bardiarastin I finished it, can you review it again?
