fixed this for me

I know this is old, but google got me here. So let's say the solution in 2018 for python3 on OSX.

<code>brew install mysql-client
echo 'export PATH="/usr/local/opt/mysql-client/bin:$PATH"' &gt;&gt; ~/.bash_profile
source ~/.bash_profile
pip install mysqlclient
</code>

blocks|key|1173244|text|如果使用mysql+dmg文件安装mysql，则需要编辑~/.bash_profile并包含以下内容：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1173245|export+DYLD_LIBRARY_PATH=/usr/local/mysql/lib:$DYLD_LIBRARY_PATH|code-block|syntax|javascript|1173246|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

If you are using the mysql dmg file to install mysql you will need to edit your ~/.bash_profile and include this:

<pre><code>export DYLD_LIBRARY_PATH=/usr/local/mysql/lib:$DYLD_LIBRARY_PATH
</code></pre>

blocks|key|1173034|text|是的，你需要安装这个。例如，如果您正在尝试安装mysql+gem，您将需要mysql库的头文件。这是因为一些gem需要编译本地扩展，所以它们需要扩展使用的任何第三方库的头文件。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1173035|在Mac上，我建议使用MacPorts来管理这些库/头文件的安装。|1173036|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

Yes you will need to install this. For example if you are trying to install the mysql gem you will need the headers for the mysql library. This is because some gems need to compile native extensions, so they need the header files for any 3rd party libraries that the extensions uses.

On Mac OS X I recommend using MacPorts to manage the installation of these libraries/headers.

Those instructions are for Debian type Linuxes. The closest thing to Debian for OS X is <a href="http://finkproject.org/" rel="nofollow noreferrer">Fink</a>. After getting that installed and set up, you can say <code>fink install mysql-unified-dev</code> to get essentially the same thing as asking for <code>libmysqlclient15-dev</code> on a Debian or Ubuntu type system.

Beware that Fink installs its packages in <code>/sw</code>, and not all build scripts know to look there for libraries and headers. You might have to give custom build options to get it to figure this out.

A path that may be more successful is to simply download the <a href="http://dev.mysql.com/downloads/mysql/5.0.html#macosx-dmg" rel="nofollow noreferrer">MySQL 5.0 package for Mac OS X</a>. That should include the same development files as <code>libmysqlclient15-dev</code>, and as a bonus will put them in places more likely to be found by your gem.

(Why 5.0, by the way? Because that's what corresponds to ABI version 15, which your package apparently requires. Maybe it will in fact work with 5.1, or 5.4, or 6.0, but that would be a risk you'd have to decide to take on your own.)

Does OSX need an install of libmysqlclient15-dev? I'm trying to compile a gem that is failing and a lot of sources says to install "libmysqlclient15-dev" but I only see this for Linux, not OSX. Am I missing something here?

libmysqlclient15-dev on macs?

Ubuntu

Debian

Linux

OSX需要安装libmysqlclient15-dev吗？我正在尝试编译一个失败的gem，很多资源都说要安装"libmysqlclient15-dev“，但我只在Linux上看到了这一点，而没有看到OSX。我是不是漏掉了什么？
