即使安装了mysql-devel，ruby-devel和rubygems之后也无法运行安装MySQL gem的Fedora 14

Question

我正在尝试通过

安装mysql gem

sudo gem install mysql --version 2.7

但是，我收到以下错误：

Building native extensions.  This could take a while...
...........
ERROR:  Error installing mysql:
    ERROR: Failed to build gem native extension.

*** 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.

有什么想法吗？

Answer 1

尝试的事情：

gem install mysql -- --with-mysql-config=/usr/local/mysql/bin/mysql_config

当然使用mysql_config所在的路径。如果您已经安装了mysql客户端，那么mysql_config将会存在

gem install mysql -- \
--with-mysql-include=/usr/include/mysql \
--with-mysql-lib=/usr/lib/mysql

使用lib和header所在的路径用于mysql。
