在R中启动shell()中的OneDrive会被卡住
在R中启动shell()中的OneDrive会被卡住
提问于 2022-05-19 15:14:45
我最近问了这个问题：Import synced OneDrive files，但没有给出明确的答案，尽管它让我更多地使用了shell()命令。
我想做以下几点：
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，以强制进行新的同步，而不需要物理打开文件。
使用第一个shell命令，OneDrive会很快关闭。然而，在第二个命令中，我的R被卡住了。它将向我展示以下信息：
[OneAuth:Error:9zj9x:00000000-0000-0000-0000-000000000000] OneAuth is not configured
[OneAuth:Error:9zj9x:00000000-0000-0000-0000-000000000000] OneAuth is not configured
[OneAuth:Info:9zkae:xxx] Start task AcquireCredentialSilently [0]
[OneAuth:Info:9zkad:xxx] Finish task AcquireCredentialSilently [0]
[OneAuth:Info:9zkae:xxx] Start task AcquireCredentialSilently [1]
[OneAuth:Info:9zkad:xxx] Finish task AcquireCredentialSilently [1]
[OneAuth:Info:9zkae:xxx] Start task AcquireCredentialSilently [2]
[OneAuth:Info:9zkad:xxx] Finish task AcquireCredentialSilently [2]
[OneAuth:Info:9zkae:xxx] Start task AcquireCredentialSilently [3]
[OneAuth:Info:9zkad:xxx] Finish task AcquireCredentialSilently [3]
[OneAuth:Info:9zkae:xxx] Start task AcquireCredentialSilently [4]
[OneAuth:Info:9zkad:xxx] Finish task AcquireCredentialSilently [4]
[OneAuth:Info:9zkae:xxx] Start task AcquireCredentialSilently [5]
[OneAuth:Info:9zkad:xxx] Finish task AcquireCredentialSilently [5]
[OneAuth:Info:9zkae:xxx] Start task AcquireCredentialSilently [6]
[OneAuth:Info:9zkad:xxx] Finish task AcquireCredentialSilently [6]
[OneAuth:Info:9zkae:xxx] Start task AcquireCredentialSilently [7]
[OneAuth:Info:9zkad:xxx] Finish task AcquireCredentialSilently [7]
[OneAuth:Info:9zkae:xxx] Start task AcquireCredentialSilently [8]
[OneAuth:Info:9zkad:xxx] Finish task AcquireCredentialSilently [8]
[OneAuth:Info:9zkae:xxx] Start task AcquireCredentialSilently [9]
[OneAuth:Info:9zkad:xxx] Finish task AcquireCredentialSilently [9]
[OneAuth:Info:9zkae:xxx] Start task AcquireCredentialSilently [10]
[OneAuth:Info:9zkad:xxx] Finish task AcquireCredentialSilently [10]我可以看到文件在OneDrive中是同步的，但是即使所有文件都是同步的，R进程也没有停止。当我试图关闭该过程时，它会告诉我：
子进程没有响应。R会终止它
有什么解决办法吗？我也想知道是什么原因造成了这个问题。

将wait = F放在shell函数中，似乎得到了这样的回答：
shell("cd C:/Users/xxx/AppData/Local/Microsoft/OneDrive && onedrive.exe", wait = F)这样，启动OneDrive将是一个后台进程，而不是启动子进程。如果您想确保其余的代码只有在OneDrive完全重新生成之后才能运行，那么您可以使用Sys.sleep()。此外，请确保您的invalidateLater计时器足够大，以便在同步期间不重置OneDrive。
