adding RMySQL package to R fails (on Windows)?

问题

I can\'t figure out why my RMySQL package won\'t install - here\'s what I get:

> install.packages(\'RMySQL\',type=\'source\')
trying URL \'http://cran.mirrors.hoobly.com/src/contrib/RMySQL_0.7-5.tar.gz\'
Content type \'application/x-gzip\' length 160769 bytes (157 Kb)
opened URL
downloaded 157 Kb

* installing *source* package \'RMySQL\' ...
ERROR: configuration failed for package \'RMySQL\'
* removing \'C:/PROGRA~1/R/R-212~1.0/library/RMySQL\'

The downloaded packages are in \'(foo)\'

Warning message:
In install.packages(\"RMySQL\", type = \"source\") : installation of package \'RMySQL\' had    non-zero exit status

I don\'t think it\'s a problem with the MySQL install, as the right values seem to be in the registry:

> Sys.getenv(\'MYSQL_HOME\')
                 MYSQL_HOME \"C:/PROGRA~1/MySQL/MYSQLS~1.1/\" 
> readRegistry(\"SOFTWARE\\\\MySQL AB\", hive=\"HLM\", maxdepth=2)
$`MySQL Server 5.1`
$`MySQL Server 5.1`$DataLocation
[1] \"C:\\\\Documents and Settings\\\\All Users\\\\Application Data\\\\MySQL\\\\MySQL Server 5.1\\\\\"

$`MySQL Server 5.1`$FoundExistingDataDir 
[1] \"0\"

$`MySQL Server 5.1`$Location 
[1] \"C:\\\\Program Files\\\\MySQL\\\\MySQL Server 5.1\\\\\"

$`MySQL Server 5.1`$Version
[1] \"5.1.54\"

Puzzled. Any help would be greatly appreciated!

The basic process is described here, but there are several hints, So I will describe the whole solution (please change the R version and paths if needed):

Install latest RTools from here
install MySQL or header and library files of mysql
create or edit file C:\Program Files\R\R-2.12.1\etc\Renviron.site and add line like MYSQL_HOME=C:/mysql (path to your mysql files)
copy libmysql.lib from mysql/lib to mysql/lib/opt to meet dependencies.
copy libmysql.dll to C:\Program Files\R\R-2.12.1\bin or to windows/system32 directory.
run install.packages('RMySQL',type='source') and wait while compilation will end.

This worked for me on Windows 7 64 bit, so there should be no problems with 32 bit versions

Initialy posted here (similar question).

First I would try following the directions on this page: http://biostat.mc.vanderbilt.edu/wiki/Main/RMySQL

Then, ensure that you actually have a MySQL client on your computer, not just the server itself. I've had a problem myself where I had to use an older binary for the client, but you can download these from mysql website.

回答3:

I created a binary which might work for people:

http://kenahoo.blogspot.com/2011/09/rmysql-binary-for-windows-7.html

I basically followed all these directions, including the ones at the Vanderbilt page, but for one reason or another it doesn't always seem to work. Anyway, hope this might be helpful for people who have the same versions of stuff I used.

I was having this same problem on Windows 7 with R 2.12.1 x64 and resolved it by:

Changing the R directory in my PATH variable to C:\Program Files\R\R-2.12.1\bin\x64 (rather than just ...\R-2.12.1\bin).
Copying ...\MySQL Server 5.5\lib\libmysql.dll to ...\MySQL Server 5.5\bin\.
Running R CMD INSTALL RMySQL_0.7-5.tar.gz in cmd.exe (install.packages('RMySQL',type='source') in R still would not work).

回答5:

I came across this step-by-step guide to install RMySQL under Windows7 64bit.

http://www.ahschulz.de/2013/07/23/installing-rmysql-under-windows/

The software I used are:

Windows 8 OS
R3.0.2 - 64bit
Rtools 3.1
MySQL Server Community Edition 5.6 - 64bit

Following the above guide (with screenshots provided), my installation and loading of the RMySQL package works.

Many thanks to Arne Hendrik Schulz!

回答6:

As Marek said. There is no windows binary for this package. I had similar troubles on my Mac when I tried to install RPostgreSQL (because there's no binary for Mac) in the end I had to compile it on my own and modify several files.

For the MySQL part(if you don't know much about MySQL), you might want to use WAMP which is admittedly more than you need, but easy to install and to start and shut down.

For some compiling help you might be interested in Rtools

HTH

BTW: What kind of windows do you run (sry, if I missed it)

回答7:

You however there is one additional requirement at present (with the MySQL server version 5.5 & R2.12.1) follow thehttp://biostat.mc.vanderbilt.edu/wiki/Main/RMySQL instructions at present as the locations of the libmySQL.dll differs to what is expected in the package.

i.e. for the 64bit compiling. it expects the libmySQL.dll to be in "${MYSQL_HOME}"/bin/libmySQL.dll so simply copy the dll over to the /bin dir and it will now compile.

for the 32bit compilling. the libmySQL.lib is expected in "${MYSQL_HOME}"/lib/opt/libmysql.lib again moving this should solve the problem.

Alternatively, if you don't want to or can't move these files. Then you can edit the source code files: Makevars.win Makevars.win32 Makevars.win64 appropriately pointing to /lib/libmysql.dll /lib/libmysql.lib

Add MySQL and RTools directory to the PATH!

Here is my PATH ; ~blah~;C:\Program Files\MySQL\MySQL Server 5.5\bin;c:\rtools\bin;C:\Rtools\gcc-4.6.3\bin;

I was working for last 2 days on Installation of R with RMySQL package, finally got the solution for that, here are the steps to install RMySQL package:-

DOWNLOAD SOFTWARE FROM THE FOLLOWING LINKS: *a. R2.13.2: Download R from http://cran.stat.sfu.ca/index.html

  b. RTools 214:  Download RTools from http://cran.cict.fr

  c. RMySQL 0.8-0.tar.gz: Download RMySQL from 
  http://biostat.mc.vanderbilt.edu/wiki/main/RMySQL/RMySQL_0.8-0.tar.gz

  d. MySQL Server 5.0: download it from http://dev.mysql.com

  e. RSTUDIO (optional): download it from http://rstudio.org*

SET THE FOLLOWING ENVIRONMENT VARIABLES

 * a. MYSQL_HOME : <drive>/path to MySQL installation folder
      e.g. MYSQL_HOME= C:\Program Files\MySQL\MySQL Server 5.5\ 

  b. R_HOME: <drive>/path to R installation
     e.g. R_HOME=C:\Program Files\R\R-2.13.2\

  c. PATH: Modify path to accommodate the above variables. *

Be sure that the following paths areincluded in your Windows PATH variable: \Rtools\2.14\bin \Rtools\2.14\MinGW\bin \Rtools\2.14\MinGW64\bin

CREATE FOLDER AND COPY FILES

a. OPT: Create a folder OPT under C:\Program Files\MySQL\MySQL Server 5.5\lib and copy
MYSQLLIB.LIB the above path. Also copy libmysql.dll to \\R\R-2.14.0\bin\ (64 bit) Or \\R\R-2.14.0\bin\i386\ (32 bit) and to C:\Windows\System32.

b. Renviron.site: create or edit a file \\R\R-2.14.0\etc\Renviron.site and add a line: MYSQL_HOME =”C:/Program Files/MySQL/MySQL Server 5.5/” NB: USE FORWARD SLASH AND DOUBLE QUOTES HERE

c. libMySQL.dll: Copy this file to C:\Program Files\R\R-2.13.2\bin\i386 as well as C:\Program Files\R\R-2.13.2\bin

RUN COMMANDS

a. Install.Packages: Run R GUI by clicking on the R icon on desktop or from Start menu. Type INSTALL.PACKAGES(“RMySQL”,type=”Sources”). This will download the required software from repositories.

b. Command Prompt: Copy the downloaded zip file (in step 4.a.) and paste it under R installation folder. Go to start menu and open Command Prompt. Go to the R installation folder and type R CMD INSTALL RMySQL_0.8-0.tar.gz

  *COMMANDS:
  >library(RMySQL)
   >drv = dbDriver("MySQL")
   >con = dbConnect(drv,host="localhost",dbname="test",user="root",pass="root")
   >album = dbGetQuery(con,statement="select * from t_master")
   >album*

18 months later, new laptop, same problem. Returning to the scene of the crime - sorry January 2011 self; we're in the future, and this installation still isn't any fun.

Lessons learned:

-Updated RTools are essential. Get them.

-Are you seeing an error along the lines of .onLoad failed in loadNamespace() for 'RMySQL', details? This seems to mean that there's a problem with your system environment variables.

In R, run

Sys.getenv('MYSQL_HOME')

If it spits back a path like

 [1] "C:\\Program Files\\MySQL\\MySQL Server 5.6"

you're good. But if it gives you empty string, you need to set this.

These are all Windows 7 directions, but the process is pretty similar in XP, if memory serves.

1) Bring up System Properties > Advanced > Environment Variables.

2) In the lower 'System Variables' pane, click 'New'.

3) Variable name is MYSQL_HOME and value is whatever the path is to your MySQL installation - mine was C:\Program Files\MySQL\MySQL Server 5.6

Newer versions of MySQL don't seem to create an environment variable on install - that and the lack of binaries for RMySQL explain why this questions has garnered 8,000 hits.

-Still stuck? Here are two additional in-depth writeups: 1, 2

Following worked for me in red hat linux

wget http://cran.r-project.org/src/contrib/RMySQL_0.9-3.tar.gz
sudo R CMD INSTALL  --configure-args='--with-mysql-inc=/usr/include/mysql' --configure-args='--with-mysql-lib=/usr/lib64/mysql' RMySQL_0.9-3.tar.gz
