r - RMySQL在Fedora 28，Rstudio 1.1.4版上安装错误，

Question

每当我尝试在Rstudio上安装RmySQL时，如果我已经安装了所有必需的依赖项，它就会给我这个“编译器”错误。

我试图通过dnf命令从fedora中删除Mysql，但还是一样，尝试了“dnf install c-cran-rmysql”，但是它没有给我结果..

您的答案在此行之后:

Configuration failed because libcurl was not found. Try installing:

安装 libcurl-devel程序包，如果尚未安装 libcurl，它也将安装。
dnf install libcurl-devel
失败的话，您可以安装 RMariaDB软件包，因为 RMySQL基于正在逐步淘汰的代码，所以它是最新的。
