推荐答案

是否有可能尝试写入只读文件?从堆栈跟踪中，您正在调用插入方法.

Is it possible you are trying to write to a read only file? From the stack trace you are invoking an insert method.

此外，您是否有权访问该文件?我的意思是对文件本身及其父目录(及其父目录等)的读取权限.

Also, do you have permissions to access the file? I mean read permissions on the file itself as well as on its parent directory (and its parent and so on).
