Fix NativeCommandError

✅ Solution

NativeCommandError in unsloth often arises from failed builds of native dependencies like llama.cpp, usually due to missing system dependencies or build environment misconfigurations. Ensure you have necessary build tools installed (e.g., a valid C++ compiler, CMake) and that your environment PATH is correctly configured to find them; then, try reinstalling the problematic dependency with `--no-cache-dir` to force recompilation and resolve transient issues.
