Fixes #25998. Fixes https://github.com/denoland/deno/issues/25928. Originally I was just going to make this an error message instead of a panic, but once I got to a minimal repro I felt that this really should work. The panic occurs when you have `nodeModulesDir: manual` (or a package.json present), and you have an npm package with a tag in your deno.json (see the spec test that illustrates this). This code path only actually executes when trying to choose an appropriate package version from `node_modules/.deno`, so we should be able to fix it by storing some extra data at install time. The fix proposed here is to repurpose the `.initialized` file that we store in `node_modules` to store the tags associated with a package. Basically, if you have a version requirement with a tag (e.g. `npm:chalk@latest`), when we set up the node_modules folder for that package, we store the tag (`latest`) in `.initialized`. Then, when doing BYONM resolution, if we have a version requirement with a tag, we read that file and check if the tag is present. The downside is that we do more work when setting up `node_modules`. We _could_ do this only when BYONM is enabled, but that would have the downside of needing to re-run `deno install` when you switch from auto -> manual, though maybe that's not a big deal. |

Deno
Deno
(/ˈdiːnoʊ/, pronounced
dee-no) is a JavaScript, TypeScript, and WebAssembly runtime with secure
defaults and a great developer experience. It's built on V8,
Rust, and Tokio.
Learn more about the Deno runtime in the documentation.
Installation
Install the Deno runtime on your system using one of the commands below. Note that there are a number of ways to install Deno - a comprehensive list of installation options can be found here.
Shell (Mac, Linux):
curl -fsSL https://deno.land/install.sh | sh
PowerShell (Windows):
irm https://deno.land/install.ps1 | iex
Homebrew (Mac):
brew install deno
Chocolatey (Windows):
choco install deno
Build and install from source
Complete instructions for building Deno from source can be found in the manual here.
Your first Deno program
Deno can be used for many different applications, but is most commonly used to
build web servers. Create a file called server.ts and include the following
TypeScript code:
Deno.serve((_req: Request) => {
return new Response("Hello, world!");
});
Run your server with the following command:
deno run --allow-net server.ts
This should start a local web server on http://localhost:8000.
Learn more about writing and running Deno programs in the docs.
