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

typescript 5.7.3       

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
