根因分析
尝试打开指定路径下不存在的文件,可能由于拼写错误或缺少目录。
English
Attempting to open a file that does not exist at the specified path, possibly due to typo or missing directory.
解决方案
-
95% 成功率 Check file existence before opening and use filepath.Join for path construction
if _, err := os.Stat(filepath.Join(dir, filename)); os.IsNotExist(err) { return err } f, err := os.Open(filepath.Join(dir, filename))
无效尝试
常见但无效的做法:
-
Using absolute path incorrectly
60% 失败
Hardcoding absolute paths breaks portability; relative paths may work.
