研究方向
The bug is introduced in commit a64d497 at line 362 of source map support.js, where `process` is used without a guard. The error occurs in Chrome because `process` is not defined. To fix, add a check for `typeof process !== 'undefined'` before accessing `process.env`. Alternatively, consider bundling with a webpack define plugin to replace `process` references. Check the issue comments for any context about the intended behavior. Then create a pull request that conditionally uses `process` only when available.
