研究方向
Investigate the pip source code, particularly the install command and how it handles the target flag during upgrades. Look at how scripts are installed and removed, focusing on the logic that deletes existing scripts in the target bin folder. Examine the comments in issue #8063 for any proposed solutions or maintainer guidance. The fix likely involves ensuring that only scripts from the upgraded package are replaced, not all scripts in the target directory.
