tryCatch抑制错误消息 [英] tryCatch suppress error message

问题描述

我正在使用 tryCatch 来捕获发生的任何错误。但是，即使我抓到并返回相应的错误值，看起来错误仍然在我的批处理系统的日志中报告。有没有办法完全抑制错误，只是继续处理我提供的错误？

I am using tryCatch to catch any errors that occur. However, even though I catch them and return the appropriate error value, it looks like the error is still reported in the logs of my batch system. Is there a way to completely suppress the error and simply proceed with the error handling I provide?

推荐答案

确保你不是（1）在错误处理代码中返回错误，（2）打印到 stderr 。注意这里有一个消息将其输出发送到 stderr 。

Make sure you're neither (1) returning an error, nor (2) printing to stderr in your error handling code. Note one gotcha here is message sends its output to stderr.

满足这两个条件的最小方法是 tryCatch（expr，error = function（e）{}）

A minimal way to fulfills both conditions is tryCatch(expr, error = function(e) {})
