在小牛队中安装RMySQL

我在安装RMySQL时遇到问题.我试图通过以下方式从源代码安装它:

install.packages("/path/to/package/RMySQL_0.9-3.tar.gz",repos = NULL,type="source")

然后我得到:

Configuration error:
  could not find the MySQL installation include and/or library
  directories.  Manually specify the location of the MySQL
  libraries and the header files and re-run R CMD INSTALL.

INSTRUCTIONS:

1. Define and export the 2 shell variables PKG_CPPFLAGS and
   PKG_LIBS to include the directory for header files (*.h)
   and libraries, for example (using Bourne shell syntax):

      export PKG_CPPFLAGS="-I"
      export PKG_LIBS="-L -lmysqlclient"

   Re-run the R INSTALL command:

      R CMD INSTALL RMySQL_.tar.gz

2. Alternatively, you may pass the configure arguments
      --with-mysql-dir= (distribution directory)
   or
      --with-mysql-inc= (where MySQL header files reside)
      --with-mysql-lib= (where MySQL libraries reside)
   in the call to R INSTALL --configure-args='...' 

   R CMD INSTALL --configure-args='--with-mysql-dir=DIR' RMySQL_.tar.gz

ERROR: configuration failed for package ‘RMySQL’
* removing ‘/Library/R/3.1/library/RMySQL’
Warning in install.packages :
  installation of package ‘/path/to/package/RMySQL_0.9-3.tar.gz’ had non-zero exit status

因为我正在接受指示,所以我可能因此而大声喊叫,但是这个术语已经过去了,而且我在过去的两个小时里一直在努力.有人可以帮忙吗？
