根因分析

项目 Assets 文件夹中的文件被外部程序（例如版本控制、文本编辑器或防病毒软件）锁定，阻止 Unity 在刷新期间读取或写入它。

English

A file in the project's Assets folder is locked by an external program (e.g., version control, text editor, or antivirus), preventing Unity from reading or writing it during refresh.

解决方案

  1. Identify and close the locking process: Use tools like Sysinternals Handle.exe to find which process has a lock on the file. In Command Prompt: handle.exe -a "Assets/Resources/data.asset" then close the identified application (e.g., Notepad++ or Git).
  2. Exclude the Unity project folder from antivirus real-time scanning to prevent locks. Then restart Unity and perform a refresh.

无效尝试

常见但无效的做法:

  1. Run Unity as administrator 80% 失败

    Administrator privileges do not unlock files held by other processes; the lock persists.

  2. Delete the locked file and recreate it 70% 失败

    Deleting may succeed but the new file can be locked again if the external process is still running.
