R VSTS中的SSH任务显示错误，即使它是'；这只是日志

我目前正致力于在Azure中自动配置Ubuntu虚拟机，并使用shell脚本、Rcode和VSTS管道在其上自动部署R-Studio。一切进展顺利，但有一件事一直困扰着我，那就是VSTS发布管道中的输出。我正在运行R-code来安装R-packages，它们安装得很好，没有任何错误，但是VSTS中的输出日志显示了以下内容（这是一次重新运行，其中R-packages已经安装，并且是一种期望的行为）：

现在一切都会好起来的，除了它不断向我弹出

#[error]

消息，而事实上这不是一个错误。如果log向STDERR写入任何内容，我可以取消选中失败选项，但我不认为这是一个解决方案，因为这样在发生错误时我可能会忽略真正的错误

还有其他人经历过吗？这是SSH任务中的错误还是我的R代码中的错误。

那些

##error

识别您的命令在标准错误上打印出的内容

解决方案：

• 首先，通过清理提供给正在使用的命令的输入来避免它们。也许您的输入脚本需要重新编写，而这些实际上是需要修复的错误

• 评估stderr的内容是“警告”还是“错误”。在前一种情况下，您可以尝试抑制这些警告（例如。

  库（dplyr，warn.conflicts=FALSE）；

• 如果命令仍然成功，但在标准错误上打印了任何内容，最后一种方法是在VSTS任务上禁用“如果日志将任何内容写入STDERR，则失败”选项

---

您正在执行的命令的实际输出是什么？似乎VSTS生成代理将它们误解为

##vso[task.logissue]错误

命令。如果我直接在VM上执行相同的命令，我会得到相同的输出，只是它没有显示##[error]并且没有记录为错误我也有同样的问题。运行

certbot

，所以我得到了一个bog标准certbot输出负载，它肯定没有写入

STDERR

-它只是记录进度。但是Azure DevOps将其报告为错误并使脚本失败，即使在远程ssh主机上一切都成功。更新：我有多大的错误作为…#facepalm，Rscript不会有问题，因为即使安装包也会以红色错误返回此错误，并写入到STDERR
