error: unexpected argument '--mapdir' found #132

Closed danielwcho closed 1 month ago

Describe the bug

when I try to run the code in the picture, I get 

error: unexpected argument '--mapdir' found

  tip: to pass '--mapdir' as a value, use '-- --mapdir'

Usage: wasmtime run [OPTIONS] <WASM>...

Reproduction steps

  1. Checked my wasmtime version (wasmtime-cli 22.0.0 (761f044ef 2024-06-20)
  2. I am pretty sure every files are in the correct directory

Expected behavior

The 🐇 woke up with a smile. The 🌅 was shining on his face. A 🥕 was waiting for him on the table. He will put on his 👖 and get out of the 🏠 for a walk.

i just stumbled upon the same issue.

it seems like a while ago wasmtime redesigned their cli interface

--mapdir GUEST_DIR::HOST_DIR has been replaced by --dir HOST_DIR::GUEST_DIR.

so in your case, instead of 

wasmtime run \
  --mapdir /workdir::$PWD/workdir \
  --mapdir /::$PWD/tmp/unpacked \
  tmp/unpacked/bin/python-3.12.0.wasm

this should do the trick:

wasmtime run \
  --dir $PWD/workdir::/workdir \
  --dir $PWD/tmp/unpacked::/ \
  tmp/unpacked/bin/python-3.12.0.wasm
