Works for me. Can you provide some reproduction steps? Maybe this is #15826?

The example above fails in repl:

but it works if it's in a file.

Other weird examples:

// This works
const react = await import("npm:react");

// This doesn't work
const react = await import(`npm:react`);

// This doesn't work
const react = await import("npm:" + "react");

Other example, not sure if it's a bug:

// error: Uncaught (in promise) Error: Cannot find module 'react'
const server = await import("npm:react-dom@18.2.0/server");

// This works
const react = await import("npm:react");
const dom = await import("npm:react-dom@18.2.0/server");

We haven't implemented npm specifiers in the repl yet. I've renamed this issue and added it to the roadmap.

The non-analyzable specifiers example is probably #15826 and the react-dom one is peer dependency support, which we don't have yet either.

okay, thx

Would be cool.
