seccomp filter not found after npm install -g @anthropic-ai/sandbox-runtime
증상
/sandbox reports “seccomp filter: not installed” even after following the suggested install command (npm install -g @anthropic-ai/sandbox-runtime). The files are on disk but Claude Code never finds them, requiring a manual settings patch.
원인
Environment variable, configuration file, or initialization parameter missing, malformed, or incorrectly scoped.
해결법
Manually add explicit paths to ~/.claude/settings.local.json:
{
"sandbox": {
"seccomp": {
"bpfPath": "<npm-global-prefix>/lib/node_modules/@anthropic-ai/sandbox-runtime/vendor/seccomp/x64/unix-block.bpf",
"applyPath": "<npm-global-prefix>/lib/node_modules/@anthropic-ai/sandbox-runtime/vendor/seccomp/x64/apply-seccomp"
}
}
}
