console.error([data][, ...args])


    使用换行符打印到 stderr。 可以传入多个参数,其中第一个用作主要消息,所有其他参数用作类似于 printf(3) 的替换值(所有参数都传给 util.format())。

    Prints to stderr with newline. Multiple arguments can be passed, with the first used as the primary message and all additional used as substitution values similar to printf(3) (the arguments are all passed to util.format()).

    const code = 5;
    console.error('error #%d', code);
    // Prints: error #5, to stderr
    console.error('error', code);
    // Prints: error 5, to stderr

    If formatting elements (e.g. %d) are not found in the first string then util.inspect() is called on each argument and the resulting string values are concatenated. See util.format() for more information.
