--redirect-warnings=file


将进程警告写入给定文件而不是打印到标准错误。 如果文件不存在则创建,如果存在则追加。 如果在尝试将警告写入文件时发生错误,则警告将改为写入标准错误。

file 名称可以是绝对路径。

Write process warnings to the given file instead of printing to stderr. The file will be created if it does not exist, and will be appended to if it does. If an error occurs while attempting to write the warning to the file, the warning will be written to stderr instead.

The file name may be an absolute path. If it is not, the default directory it will be written to is controlled by the --diagnostic-dir command line option.
