在 R 中的 shell() 内启动 OneDrive 卡住了

Question

我最近问了这个问题：Import synced OneDrive files 但没有给出明确的答案，虽然它让我更深入地研究使用 shell() 命令。

我正在尝试执行以下操作：

observe({
    invalidateLater(60*1000, session)
    shell("cd C:/Users/xxx/AppData/Local/Microsoft/OneDrive && onedrive.exe /reset")
    shell("cd C:/Users/xxx/AppData/Local/Microsoft/OneDrive && onedrive.exe")
    list <- list.files(path = "../../folder/folder", pattern = ".xlsx", recursive = T)
    
    ...
})

这背后的想法是强制关闭 OneDrive 并重新启动它以强制进行不需要物理打开文件的新同步。

使用第一个 shell 命令，OneDrive 关闭得非常快。但是，在第二个命令中，我的 R 卡住了。它将向我显示以下消息：

[OneAuth:Error:9zj9x:00000000-0000-0000-0000-000000000000] OneAuth is not configured

我可以看到 OneDrive 中的文件正在同步，但即使据说所有文件都已同步，R 进程也不会停止。当我尝试关闭进程时，它告诉我：

Child process not responding. R will terminate it

有什么解决办法吗？我也想知道是什么导致了这个问题。

Answer 1

似乎通过将 wait = F 放入 shell 函数中来回答，如下所示：

shell("cd C:/Users/xxx/AppData/Local/Microsoft/OneDrive && onedrive.exe", wait = F)

这样启动 OneDrive 将是后台进程，而不是启动子进程。如果您想确保其余代码仅在 OneDrive 完全重新同步后运行，您可以使用 Sys.sleep()。此外，请确保您的 invalidateLater 计时器足够大，不会在同步期间重置 OneDrive
