R与“碰撞”；“非法操作被抓获”；安装gert时

我正在使用R3.4.4和Ubuntu 16.04，并遵循gert安装说明。我已经安装了libgit2 dev，但gert安装崩溃，错误如下：

***非法经营被捕***
地址0x7fbf6f06b405，原因为“非法操作数”
回溯：
1:.调用（R\u git\u config\u list，NULL）
2:git_config_global（）
3:doTryCatch（返回（expr）、名称、parentenv、处理程序）
4:tryCatchOne（expr、name、parentenv、handlers[[1L]]）
5:tryCatchList（expr、类、parentenv、处理程序）
6:tryCatch（expr，error=function（e）{call我遇到了同样的问题，这为我解决了。试试看

Sys.setenv(USE_SYSTEM_LIBGIT2=1)
install.packages("gert")

谢谢，成功了！没问题，很乐意帮忙！
