Question

我尝试安装mysql2 gem，但我看到了这个错误。

Using --with-mysql-dir=C:/mysql-connector
-----
checking for main() in -llibmysql... no
*** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of necessary
libraries and/or headers.  Check the mkmf.log file for more details.  You may
need configuration options.

Provided configuration options:
        --with-opt-dir
        --without-opt-dir
        --with-opt-include
        --without-opt-include=${opt-dir}/include
        --with-opt-lib
        --without-opt-lib=${opt-dir}/lib
        --with-make-prog
        --without-make-prog
        --srcdir=.
        --curdir
        --ruby=C:/Ruby200-x64/bin/ruby
        --with-mysql-dir
        --with-mysql-include
        --without-mysql-include=${mysql-dir}/include
        --with-mysql-lib

        --with-mysql-lib
        --without-mysql-lib=${mysql-dir}/lib
        --with-libmysqllib
        --without-libmysqllib


Gem files will remain installed in C:/Ruby200-x64/lib/ruby/gems/2.0.0/gems/mysql2-0.3.14 for inspec
Results logged to C:/Ruby200-x64/lib/ruby/gems/2.0.0/gems/mysql2-0.3.14/ext/mysql2/gem_make.out

我已尝试将llibmysql.dll文件复制到Ruby/bin和Ruby/lib个文件夹，但尝试我看不到成功。

如果有人遇到此问题，请告诉我（我猜这是特定于Windows 7 + ROR + Mysql）

这对我有用：

gem install mysql2 -- '--with-mysql-lib="c:\Program Files\MySQL\MySQL Server 5.5\lib" --with-mysql-include="c:\Program Files\MySQL\MySQL Server 5.5\include"'
