描述

See discussion in https://github.com/avajs/ava/pull/3015. Certain Node.js flags stop worker threads from working. We should recognize that error (ERR_WORKER_INVALID_EXEC_ARGV) and print a useful error message so users know to disable worker threads in AVA.

研究方向
Investigate the error handling in AVA, specifically how worker threads are managed. Reference the discussion in PR #3015 to understand the exact Node.js flags that cause the error. Look at the existing error handling mechanism in the AVA codebase to determine where to add the detection of `ERR WORKER INVALID EXEC ARGV`. Suggest a location in the code (e.g., in the worker setup file) and propose a message that guides users to disable worker threads.
