deno vendor with importMap fails to resolve modules

[cdaringe]

Problem

deno run --import-map=vendor/import_map.json mod.ts fails to resolve dependencies after dependencies vendor'd via deno vendor --import_map=....

Error: # error: Relative import path "oak/mod.ts" not prefixed with / or ./ or ../

Discussion

works:

$ deno run --import-map import_map.json  -A --unstable /app/src/bin.ts

doesn't work:

# vendor the deps, using the ~same flags as above
$ deno vendor --import-map=import_map.json /app/src/bin.ts

# run with vendored
$ deno run --import-map=/app/vendor/import_map.json --unstable --allow-env --allow-net /app/src/bin.ts
# yields:
# error: Relative import path "oak/mod.ts" not prefixed with / or ./ or ../

Reproduction

Easy!

• git clone https://github.com/cdaringe/deno-emit-esm-server.git
• cd deno-emit-esm-server
• git checkout b23071be397a2d2e7e7ca53b9df0832de3241bb9
• (optional) Prove that the server works
  • run it:deno run --import-map=import_map.json --unstable --allow-env --allow-net ./src/bin.ts (no output)
  • access it: curl http://localhost:7777/github/denoland/deno_std/main/uuid/mod.ts (observe JS emitted to stdout)
• deno vendor --import-map=import_map.json ./src/bin.ts
• deno run --import-map=vendor/import_map.json --unstable --allow-env --allow-net ./src/bin.ts
  • Observe the module resolution failure

Looks like #13697 -- Basically this is not implemented yet. You will have to manually merge the import maps manually for the time being unfortunately.
