Question

尝试在R中安装stringi包但在下面收到奇怪的错误消息。

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

查看其他帖子，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导致这种情况，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，这个问题也发生在其他软件包的安装上。以下是尝试安装DierckxSpline时的输出。

到目前为止我没有任何线索，当我谷歌它时没有任何帮助。它似乎与RStudio的Mac X问题。希望有人可以帮忙，谢谢。

Answer 1

终于得到了答案并解决了，在这里： rJava 'class not found' error with makeCluster。问题发生在.Rprofile我的library(RJDBC)行和drv <- JDBC("com.sas.net.sharenet.ShareNetDriver", "/usr/local/sas/jdbc_driver/sas.intrnet.javatools.jar", identifier.quote="")行。我不知道这是在那里。我刚删除它，问题现在解决了。

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