bundle install问题:缺少mysql.h

Question

在我的mac OSX 10.6 32位,我可以很容易地安装mysql2 gem,但不能在mini mac 10.6 64bit服务器上安装.

我在麻烦的服务器上安装了MySQL 5.5.11,而在我的家里mac MySQL 5.5.0.m2不知何故当我运行bundle install时,在服务器中它试图在家里安装mysql2.0.3.2 mysql2.0.2.6

请不要告诉我

env ARCHFLAGS =" - arch x86_64"sudo gem install mysql2 --version'= 0.2.6' - --with-mysql-config =/usr/local/mysql/bin/mysql_config

我试过了,不行.

$ PATH中包含的/ usr/local/mysql/bin也没有帮助.

错误代码:

Answer 1

我尝试了这里发布的所有解决方案,但并不幸运.我用自制软件重新安装了几次mysql但仍然没有运气.然后我遇到了一个带有解决方案的博客文章.

我编辑了mysql_config文件/usr/local/Cellar/mysql/5.6.12/bin并删除了W编译器选项 -Wno-null-conversion以及 -Wno-unused-private-field cflags和cxxflags.

这解决了gem install mysql2和的问题bundle install

Answer 2

我在redmine repo上做了一个bundle install并得到了同样的错误信息:

缺少mysql.h.请检查你的mysql安装,然后再试一次.

运行Fedora 16 64位,我所做的只是mysql-devel从发行版rpm 安装(开发包),问题解决了!

所以我认为你可以

yum install mysql-devel

或者apt-get缺少devel包.

Answer 3

对于那些没有使用brew来安装mysql并使用mysql 5.6及更高版本的人:

根据这个答案

你需要编辑mysql_config我在这里放置的内容:/usr/local/mysql-5.6.12-osx10.7-x86_64/bin

并改变cflags和cxxflags:

cflags="-I$pkgincludedir  -Wall -Os -g -fno-strict-aliasing -DDBUG_OFF " #note: end space!
cxxflags="-I$pkgincludedir  -Wall -Os -g -fno-strict-aliasing -DDBUG_OFF " #note: end space!

在这种操纵之后

$ gem install mysql2 -v '0.3.13'

完美无瑕
