Description

Hi team,

I'm encountering an issue when attempting to use the opencode command-line tool via bunx in a WSL (Windows Subsystem for Linux) environment.

Problem:
When I execute bunx opencode-ai in my WSL2 environment, Bun proceeds to download and run the tool. However, it appears to be selecting and installing opencode-linux-x64-baseline-musl in the temporary bunx cache. My WSL environment, however, uses glibc (as is typical for most WSL distributions). This results in runtime errors related to libc incompatibility when opencode-ai attempts to execute its underlying binary.

Specifically, the opencode binary (from node_modules/opencode-ai/bin/opencode within the bunx cache) fails to execute because it's compiled against musl while the system expects glibc.

Expected Behavior:
When bunx opencode-ai is executed, the opencode-ai package should correctly detect the glibc based WSL environment and ensure that the appropriate glibc compatible binary (i.e., opencode-linux-x64-baseline) is used/installed for execution.

Terminal Output:

$ bunx opencode-ai
ENOENT: no such file or directory, posix_spawn '/tmp/bunx-1000-opencode-ai@latest/node_modules/opencode-linux-x64-baseline-musl/bin/opencode'

$ ls /tmp/bunx-1000-opencode-ai@latest/node_modules
opencode-ai  opencode-linux-x64  opencode-linux-x64-baseline  opencode-linux-x64-baseline-musl  opencode-linux-x64-musl

Confirming that this also happens on native Linux. Since the automatic update to 1.1.25 on Ubuntu, it has been an issue:
