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<MysqL-include-dir>"
      export PKG_LIBS="-L<MysqL-lib-dir> -lMysqLclient"

   Re-run the R INSTALL command:


      R CMD INSTALL RMysqL_<version>.tar.gz

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

   R CMD INSTALL --configure-args='--with-MysqL-dir=DIR' RMysqL_<version>.tar.gz

ERROR: configuration Failed for package ‘RMysqL’

Warning in install.packages :
  installation of package ‘./RMysqL_0.9-3.tar.gz’ had non-zero exit status

所以我按照1所说的说法.

我输入

export PKG_CPPFLAGS="-I</usr/include/MysqL>"
export PKG_LIBS="-L</usr/lib/MysqL> -lMysqLclient"

然后再次尝试在终端上安装他们给我的命令

R CMD INSTALL RMysqL_<version>.tar.gz

而我得到;

所以抬头我发现了这个建议;

installing RMySQL gives error RS-MySQL.h:32:19: fatal error: mysql.h: No such file

并遵循它在这里所说的：

我没有这一步;

3.编辑或创建文件Renviron.site并添加包含MysqL安装位置的变量MysqL_HOME.安装R时通常不会创建该文件,因此您可能需要自己创建.您需要将它放在R Home区域的/ etc目录下.如果您不知道它在哪里,可以在R提示符下发出R.home().您将在variable = value语法中添加名为MysqL_HOME的变量.这是一个例子：
Renviron.site的位置：C：/PROGRA~1/R/R-2.11〜1.0/etc/Renviron.site
内容是：
MysqL_HOME = C：/PROGRA~1/MysqL/MysqLS~1.0/

因为,当我在Renviron.site中,它不会让我编辑任何东西,我也不清楚我应该放在那里,无论如何,我写

MysqL_HOME=C:/PROGRA~1/MysqL/MysqLS~1.0/***

但我不能保存它,它不会让我,因为它说我不允许,我不能在/ etc /中创建一个新文件或任何东西
