无法使用clang在MacOS 10.12上安装data.table包

Question

感谢您的点击。几个小时以来，我一直试图解决这个问题，但似乎没有任何效果。

我的操作系统:MacOS sierra OS版本:10.12.3 R版本:3.3.3

我已经按照数据表下载说明在这里:https://github.com/Rdatatable/data.table/wiki/Installation，但它仍然没有工作

错误消息如下所示:

*> install.packages("data.table", type = "source",
+                  repos = "http://Rdatatable.github.io/data.table")
嘗試 URL 'http://Rdatatable.github.io/data.table/src/contrib/data.table_1.10.5.tar.gz'

第一个是关于几天前不再使用的变量的警告，因为您正在安装最新的开发版本(这很好) :

fread.c:64:19: warning: unused variable 'TypeName' [-Wunused-const-variable]
static const char TypeName[NUMTYPE][10]

这是一个正确的警告，我将删除该变量。

第二个是错误:

Error in dyn.load(file, DLLpath = DLLpath, ...) : 
  無法載入共享物件 '/Library/Frameworks/R.framework/Versions/3.3/Resources/library/data.table/libs/datatable.so' ：

其他人在苹果操作系统上也发现了这一点，并且似乎在这里使用gcc而不是clang的解决方案取得了一些成功。问题似乎是在苹果操作系统上，而不是data.table.Linux或视窗上没有问题。
