捆绑软件安装问题：缺少mysql.h [英] bundle install problem: mysql.h is missing

问题描述

在我的32位Mac OSX 10.6中，我可以很容易地安装mysql2 gem，但是在mini mac 10.6 64位服务器中却不能。

我已经安装了MySQL 5.5.11在麻烦的服务器中，而在我的家庭Mac中，MySQL 5.5.0.m2
以某种方式运行捆绑安装时，在服务器中，它试图在家庭mysql2.0.2.6中安装mysql2.0.3.2。 b
$ b

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

我尝试过，不起作用。

$ PATH中包含的/ usr / local / mysql / bin也无济于事。

解决方案

我尝试了此处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mysql几次，仍然没有运气。然后我遇到了一个博客，提供了解决方案。

我在 /usr/local/Cellar/mysql/5.6.12中编辑了mysql_config文件。 / bin 并删除了
W编译器选项
-Wno-null-conversion 和
-Wno-unused-private-field
用于cflag和cxxflags。

这解决了 gem安装mysql2 和捆绑安装

参考： http://www.randomactsofsentience.com/2013/ 05 / gem-install-mysql2-missing-mysqlh-on-os.html

in my mac OSX 10.6 32 bit, I can install mysql2 gem quite easily, but not in mini mac 10.6 64bit server.

I have installed MySQL 5.5.11 in troublesome server, while in my home mac MySQL 5.5.0.m2 Somehow when I run bundle install, in server it tries to install mysql2.0.3.2 while in home mysql2.0.2.6

Please don't tell me to

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

I tried that, doesn't work.

Included /usr/local/mysql/bin in $PATH does not help as well.

解决方案

I tried all the solutions posted here, but was not lucky. I reinstalled mysql with homebrew a couple of times and still no luck. Then I came across a blog post with a solution.

I edited the mysql_config file in /usr/local/Cellar/mysql/5.6.12/bin and removed the W-compiler options -Wno-null-conversion and -Wno-unused-private-field for cflags and cxxflags.

This solved the problem with gem install mysql2 and bundle install
