RMySQL在Fedora 28上安装错误，Rstudio版本1.1.4，

Question

每当我试图在Rstudio上安装RmySQL时，它都会给我这个“编译器”错误，因为我已经安装了所有所需的依赖项。

我尝试通过dnf命令从fedora中删除Mysql，但仍然一样，尝试了"dnf c-cran-rmysql“，但没有给出结果。

你的回答是在这句话之后：

Configuration failed because libcurl was not found. Try installing:

安装libcurl-devel包，如果还没有安装libcurl，它也会安装。

dnf install libcurl-devel

否则，您可以安装RMariaDB包，因为RMySQL是基于正在逐步淘汰的代码的，所以它更符合最新情况。
