描述

When trying to revert a version that doesn't exist we get the following error message:

> gleam hex revert --package birdie --version 1.234234.2
error: Hex API failure

There was a problem when using the Hex API.

This was error from the Hex client library:

    Resource was not found

I think a much better error would look something like this:

> gleam hex revert --package birdie --version 1.234234.2

error: Hex API failure

There is no version 1.234234.2 of the package birdie.

研究方向
Locate the source of the error message 'Resource was not found' in the hex ffi crate or the gleam CLI's hex module. The error is likely generated when the Hex API returns a 404 for a non existent version. Modify the error handling to produce a more descriptive message like 'There is no version 1.234234.2 of the package birdie'. Check the existing error handling in the hex ffi crate for similar patterns.
