I found the root cause, it is because in Vite+ has a VP_TOOL_RECURSION environment variable to prevent infinite loop. When this variable is set, we can only find Node.js binary from PATH.

This env var is set after finding the correct packageManager, most package managers are JS based like yarn, npm, so it will prepend Node.js prefix into PATH. But Bun is native based, so no Node.js prefix is needed, and cause the problem.
