在Windows和Mac上交替使用润滑剂包

the following problem certainly doesn't only apply to the lubridate package and maybe this has been discussed elsewhere. Unfortunately, I don't know how to ask my question in a more generic way. Therefore here with the lubridate example:

下面的问题当然不仅仅适用于润滑剂的包装，这可能已经在其他地方讨论过了。不幸的是，我不知道如何用更一般的方式问我的问题。因此，这里以润滑油为例:

I have a database in Excel that includes dates written in Dutch in the following format:

我有一个Excel数据库，其中包含用荷兰语写成的日期，格式如下:

dd/month/yyyy (e.g. 15 Maart 2017)

dd/month/yyyy(例如2017年Maart 15)

Now I can use the dmy()command from lubridate with specifying locale = 'Dutch' on Windows. On a mac in need to specifcy locale = 'nl_NL' to not receive an error message.

现在，我可以使用来自lubridate的dmy()命令，在Windows上指定locale = 'Dutch'。在mac上，需要指定locale = 'nl_NL'以不接收错误消息。

Since I work on both systems (Windows and mac) interchangeably I am curious to find out if there is a way to avoid changing this code manually. I was thinking of try or tryCatch. I could also work with if statements and specify in earlier lines whether I work on a Windows or mac. But the latter would also require a manual entry from the user which I would like to avoid.

由于我同时使用这两个系统(Windows和mac)，我很想知道是否有一种方法可以避免手工修改这些代码。我在考虑尝试或尝试捕捉。我还可以使用if语句，并在前面几行中指定我是在Windows还是mac上工作。但是后者也需要用户手动输入，我不想这样做。

Thanks a lot for you help!

非常感谢你的帮助!

You mention:

你提到:

But the latter would also require a manual entry from the user

但后者也需要用户手动输入

That is not necessarily true, you could for example do the following:

这并不一定是真的，你可以举个例子:

if(grepl("windows",Sys.info()[['sysname']],ignore.case = T))
{
  my_locale='Dutch'
} else
{
  my_locale='nl_NL'
}

and then specify:

然后指定:

locale = my_locale

Your code should now work on Windows and Mac. However this will likely fail when you switch to Linux for example. So I wonder if there are better solutions.. Anyway, hope this helps!

您的代码现在应该可以在Windows和Mac上运行，但是当您切换到Linux时，这可能会失败。所以我想知道是否有更好的解决办法。无论如何,希望这可以帮助!
