我更新了我用 Homebrew 安装的所有软件包。MySQL 升级到 5.6.12(从 5.5.27 左右):
$ mysql --version
mysql Ver 14.14 Distrib 5.6.12, for osx10.8 (x86_64) using EditLine wrapper
现在 mysql2 gem 不再编译:
$ gem install mysql2
Building native extensions. This could take a while...
ERROR: Error installing mysql2:

mysql.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:

该文件mysql.h
存在于/usr/local/Cellar/mysql/5.6.12/include/mysql.h
. 有什么想法吗?
该文件mysql.h
没有出现,/usr/local
因为符号链接似乎比它应该更深:
$ ls -la /usr/local/include/mysql
lrwxr-xr-x 1 pupeno admin 36 21 Jun 15:18 /usr/local/include/mysql@ -> ../Cellar/mysql/5.6.12/include/mysql
代替
/usr/local/Cellar/mysql/5.6.12/include
话虽如此,我手动修复了符号链接,但编译仍然失败。所以我被困住了。
