问题描述
我在 SUSE Tumbleweed 20210618 上安装 RMySQL 时遇到了一个“新”问题。我以前使用过 RMySQL，但在项目之间，RMySQL 神秘地从 R 中消失了。
现在，当我运行“install.packages”时 - 它错误地读取了我的 mysql_config 参数（如下所示）。从 mysql_config 信息（也显示如下）可以明显看出，两者不匹配。
有没有办法“更正”设置 PKG_CFLAGS 和 PKG_LIBS 的方式 - 以便它们指向正确的位置？或者，是否存在其他问题导致这种情况持续存在？
谢谢...
这是我的“install.packages”运行：
Installing package into ‘/home/craig/R/x86_64-suse-linux-gnu-library/4.1’
(as ‘lib’ is unspecified)
trying URL 'https://cran.rstudio.com/src/contrib/RMySQL_0.10.21.tar.gz'

Configure could not find suitable mysql/mariadb client library. Try installing:
* deb: libmariadbclient-dev | libmariadb-client-lgpl-dev (Debian,Ubuntu)
* rpm: mariadb-connector-c-devel | mariadb-devel | mysql-devel (Fedora,CentOS,RHEL)
* csw: mysql56_dev (Solaris)
* brew: mariadb-connector-c (OSX)
If you already have a mysql client library installed,verify that either
mariadb_config or mysql_config is on your PATH. If these are unavailable
you can also set INCLUDE_DIR and LIB_DIR manually via:
R CMD INSTALL --configure-vars='INCLUDE_DIR=... LIB_DIR=...'

我从 mysql_config 得到的信息是：

请注意，install.packages 命令中的 PKG_CFLAGS 正在错误地读取配置文件（例如，将其转换为 -I/usr//usr/include... 而不是 -I//usr/include... ).
