v17.38.1 and above shows an error with setting up edge environment

[coaxial]

Describe the bug

netlify dev runs fine unti v17.38.0 of netlify-cli. If I use v17.38.1 or above, then I'm getting this error:

› Error: There was a problem setting up the Edge Functions environment. To try a manual installation, visit https://ntl.fyi/install-deno.

Deno seems to be present:

$ deno --version

I'm using node v20.18.3

Steps to reproduce

1. Use netlify-cli 18.38.1 or above
2. Run netlify dev
3. Get the error message

I've been having the same issue. Thanks, @coaxial, for the workaround.!

Hi folks. Thanks for reporting this.

Does this happen consistently? If you run netlify dev multiple times in a row, does it fail like this every time?

If I use v17.38.1 or above, then I'm getting this error

To clarify, are you seeing this issue with the latest netlify-cli version (19.0.0)? There have been quite a few releases since 17.38.1. Can you please run npm i -g netlify-cli@latest and try again?

Thanks!

Same problem. I have had a support ticket open since Jan 31.

With v 17.38.0, the console logs:
-Loaded function ... for serverless functions

• Loaded edge function ... for edge functions.

Above that version:

• Setting up the Edge Functions environment. This may take a couple of minutes.◈ Loaded function ... for all serverless functions
• Doesn't load the Edge Functions
• `
  ✖ Setting up the Edge Functions environment. This may take a couple of minutes.

  ``

Deno is installed.

@serhalp This was happening with any version available above v17.38.0 when I opened the issue.

In case it is helpful to anyone looking into this, here is the diff between 17.38.0 and 17.38.1 v17.38.0...v17.38.1

I spent a little time this morning (I tried netlify-cli 17.38.0, 17.38.1, and 19.1.4/latest) trying to reproduce using the netlify.toml provided by @coaxial, but I was unable to.

@coaxial, @stevenmilstein, if either of you can provide a minimal reproduction? A link to a repository would be ideal.

I think we still need more information to say for sure, but my first guess here is there's something specific to your environments that isn't interacting well with something in the Netlify CLI. Can you provide more information?

Let's start with:

• A minimal repro
• How did you install Deno? (Using the script on their website? A version manager? Something else?)
• Are you using a version manager like nvm, nodenv, asdf, etc.? (If so, what version of that tool?)
• Does netlify dev work if you remove your global Deno installation? You'll want to make sure deno is no longer in your PATH. (The Netlify CLI should automatically download Deno for you, which it installs to an internal directory. If a global installation is available, though, it will prefer that one. If we can figure out whether or not it works with an automatic install but not a global one, that might help us zero in on the issue.)
• Can you provide the result of npx envinfo? (@coaxial , I see the "Environment" section in your original post is empty. If you're using something like asdf you may need to reshim before envinfo will work correctly--I needed to, anyway.)
