[英]Installing mysql gem for ruby
I have trouble installing the mysql gem: 我在安装mysql gem时遇到问题:
gem install mysql
Fetching: mysql-2.8.1.gem (100%)
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.
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=/home/user/.rvm/rubies/ruby-1.9.2-p290/bin/ruby
--with-mysql-config
--without-mysql-config
--with-mysql-dir
--without-mysql-dir
--with-mysql-include
--without-mysql-include=${mysql-dir}/include
--with-mysql-lib
--without-mysql-lib=${mysql-dir}/lib
--with-mysqlclientlib
--without-mysqlclientlib
--with-mlib
--without-mlib
--with-mysqlclientlib
--without-mysqlclientlib
--with-zlib
--without-zlib
--with-mysqlclientlib
--without-mysqlclientlib
--with-socketlib
--without-socketlib
--with-mysqlclientlib
--without-mysqlclientlib
--with-nsllib
--without-nsllib
--with-mysqlclientlib
--without-mysqlclientlib
--with-mygcclib
--without-mygcclib
--with-mysqlclientlib
--without-mysqlclientlib
the mkmf.log file consists of heaps of gcc debug output that is of no help to me, I can post it but I bet it's more trivial like the mentioned configuration options. mkmf.log文件由gcc调试输出的堆组成,这对我没有帮助,我可以发布它,但我敢打赌,它像提到的配置选项一样琐碎。
Has anyone got experience with this on a Ubuntu1104 system? 有没有人在Ubuntu1104系统上有此经验?
Thankful for any hints! 感谢任何提示!
Cheers, Mac 欢呼声,Mac
Apparently you haven't installed MySQL development libraries necessary to compile this gem. 显然,您尚未安装编译此gem所需的MySQL开发库。 libmysqlclient-dev might help.
libmysqlclient-dev可能会有所帮助。
