即使安装了 mysql-devel、ruby-devel 和 ruby​​gems 后也无法运行安装 MySQL gem 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.

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

可以尝试的东西：

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

当然使用 mysql_config 所在的路径。如果您安装了 mysql 客户端，则 mysql_config 将会在那里，

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

使用 mysql 的 lib 和标头所在的路径。
