Root Cause

Attempting to open a file that does not exist, often due to a typo in the path or the file being deleted.

generic

中文

尝试打开不存在的文件，通常是由于路径拼写错误或文件已被删除。

Workarounds

  1. 95% success 
    Use os.OpenFile with O_RDONLY and check the error.
  2. 85% success 
    Use filepath.Abs to resolve the path and verify it.

Dead Ends

Common approaches that don't work:

  1. 50% fail

    There is a race condition between the check and the open.

  2. 60% fail

    This creates an empty file, which may not be desirable.
