unittest.mock does not work on WebAssembly build of CPython #96883
Description
Bug report
Use CPython compiled for WebAssembly and then import unittest.mock
Or visit this page and click the "Run in Browser" button to see the error.
The error shown is:
Traceback (most recent call last):
File "//__main__.py", line 2, in <module>
import unittest.mock
File "/home/runner/work/cpython-wasm-test/cpython-wasm-test/cpython/Lib/unittest/mock.py", line 26, in <module>
File "/home/runner/work/cpython-wasm-test/cpython-wasm-test/cpython/Lib/asyncio/__init__.py", line 8, in <module>
File "/home/runner/work/cpython-wasm-test/cpython-wasm-test/cpython/Lib/asyncio/base_events.py", line 18, in <module>
ModuleNotFoundError: No module named 'concurrent'
This error seems to only occur on the WebAssembly build for the browser (the Node build allows unittest.mock to be imported as expected).
Your environment
- CPython versions tested on: 3.11.0rc2
- Operating system and architecture: WebAssembly
