R .jfindClass（as.character（driverClass）[1]）中的错误：找不到类

Question

尝试在R中安装stringi软件包，但在下面得到奇怪的错误消息。

Loading required package: DBI
Loading required package: rJava
Error in .jfindClass(as.character(driverClass)[1]) : class not found
Calls: JDBC -> is.jnull -> .jfindClass
Execution halted
Warning in install.packages :
  installation of package ‘stringi’ had non-zero exit status

在其他帖子中查找，但它们都与数据库驱动程序有关。 不知道在我的情况下可能是什么原因引起的，任何帮助表示赞赏。 非常感谢。

规格：Mac OSX，R Studio，R版本为3.2.0。

更新：

显然，此问题也发生在其他软件包的安装上。 下面是尝试安装DierckxSpline时的输出。

到目前为止，我一无所知，当我使用Google时也无济于事。 RStudio似乎是Mac X的问题。 希望有人可以帮助，谢谢。

最终在这里得到了答案并解决了： makeCluster的rJava'class not found'错误 。 问题出在我的.Rprofile ，它具有行library(RJDBC)和行drv <- JDBC("com.sas.net.sharenet.ShareNetDriver", "/usr/local/sas/jdbc_driver/sas.intrnet.javatools.jar", identifier.quote="") 。 我不知道这里在那里。 我刚刚将其删除，现在问题已解决。
