我正在尝试使用安装在 /opt(LAMPP 捆绑包)中的 apache 服务器运行 gem。我尝试安装 mysql2 gem 时出错。搜索后我做了以下工作:
aptitude install libmysql-ruby libmysqlclient-dev ruby-dev
接着:
gem install mysql2 -- --with-mysql-config=/opt/lampp/bin/mysql_config --with-mysql-dir=/opt/lampp/lib/mysql --with-mysql-lib=/opt/lampp/lib/mysql/ --with-mysql-include=/usr/include/mysql
这是回应:
checking for rb_thread_blocking_region()... yes
checking for rb_wait_for_single_fd()... yes
checking for rb_hash_dup()... yes
checking for rb_intern3()... yes
checking for mysql.h... no
checking for mysql/mysql.h... yes
checking for errmsg.h... no
-----
errmsg.h is missing. please check your installation of mysql and try again.

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

Gem files will remain installed in /var/lib/gems/1.9.1/gems/mysql2-0.3.13 for inspection.
Results logged to /var/lib/gems/1.9.1/gems/mysql2-0.3.13/ext/mysql2/gem_make.out
所以,问题在于 errmsg.h 库。安装开发包后,ruby 发现其他一些缺少的库,例如'mysql.h',但不是这个。我现在不知道该怎么办......我在这里看到了很多类似问题的答案,但没有一个是有帮助的。
任何帮助将不胜感激。
