Question

我一直在尝试在我的Ubuntu 12.04服务器上安装Gitlab很长一段时间，一切顺利，直到我运行bundle install。

它说它无法安装MySQL2，但没有给出任何理由或采取纠正措施。

Gem files will remain installed in /home/gitlab/gitlab/vendor/bundle/ruby/1.9.1/gems/mysql2-0.3.11 for inspection.

An error occurred while installing mysql2 (0.3.11), and Bundler cannot continue.
Make sure that `gem install mysql2 -v '0.3.11'` succeeds before bundling.

Answer 1

它确实告诉你一个通用的可能问题：

由于某种原因无法创建Makefile，可能缺少必要的库和/或标题。检查mkmf.log文件以获取更多信息细节。您可能需要配置选项。

这是你的线索。

确保已安装MySQL客户端repo以及相关的“devel”包。 Ruby，Python，Perl等语言需要安装库和头文件，以便编译提供从语言到驱动程序的接口的本机模块。

此外，您还需要mysql_config，它由以下人员安装：

sudo apt-get install libmysqlclient-dev

我能够使用我的Ubuntu VM复制您的问题，并在安装libmysqlclient-dev后修复它。

将mysql_config放在/usr/bin/mysql_config中，gem install mysql和gem install mysql2都能成功安装。

Answer 2

谢谢，它有用，只需添加一些额外的东西

sudo apt-get install libmysqld-dev libmysqlclient-dev mysql-client

Answer 3

我在rails4中使用过这个问题的解决方案：（Ubuntu 12.04）

    1) Install MySQL from symptic manager just type "mysql-server-5.5" 
    2) use following command and install 
       sudo apt-get install mysql-client libmysqlclient-dev

Answer 4

如果您使用的是Windows 8+ x64，请查看此问题正文中提供的答案：

Installing MySQL2 Gem on Windows

修改

为了让downvoters高兴，我正在复制链接问题的内容：

清理：你在这里的原因是你可能在尝试安装这个gem，它已经失败，所以你有一些清理 do：gem uninstall mysql2

下载适用于Windows的Ruby 2.0 64位：


http://dl.bintray.com/oneclick/rubyinstaller/rubyinstaller-2.0.0-p353-x64.exe?direct

运行安装程序。记下它安装到的目录，并确保它在用户路径中。转到

Control Panel > System and Security > System - Advanced System Settings > Environment Variables

并确保ruby安装目录的bin目录的路径在LOCAL用户的PATH环境变量中（如果它在SYSTEM Path环境变量中也可以）

下载Ruby 2 64位开发套件：


http://cdn.rubyinstaller.org/archives/devkits/DevKit-mingw64-64-4.7.2-20130224-1432-sfx.exe

运行安装程序并记下安装目录的位置。说明说，一旦完成安装，您需要运行devkitvars.bat文件来设置环境变量。这不适用于Windows 8.1。您需要重复说明以设置上面＃2中描述的本地路径，为本地用户设置路径环境变量以添加ruby dev kit bin目录和ruby dev kit mingw bin目录。例如，如果开发工具包安装到c：\ ruby2devkit，并且您将ruby2安装到C：\ Ruby200-x64目录，那么您编辑路径语句如下所示：

C:\Ruby200-x64\bin;C:\ruby2-devkit\bin;c:\ruby2-devkit\mingw\bin

接下来你需要安装mysql-connector。请勿下载并运行自安装程序。而是，下载zip文件并解压缩。请注意您将其解压缩到的目录（出于本文的目的，我们假设您将其解压缩到c：\ mysql-connector：


http://dev.mysql.com/downloads/file.php?id=450612

MySQL Connector 64位中包含的libmysql.lib与mingw64-gcc编译器不兼容。您需要生成与mingw64兼容的libmysql.lib文件。

下载您需要的工具

https://structure-svm-map.googlecode.com/files/svm-map-win.zip

将此文件解压缩到本地目录，我们假设您已将其解压缩到c：\ svm-map

如前所述，编辑PATH环境路径，现在看起来像这样：

C:\Ruby200-x64\bin;C:\ruby2-devkit\bin;c:\ruby2-devkit\mingw\bin;c:\svm-map;C:\svm-map\python-mingw-lib

生成新的mysql库：

cd c:\mysql-connector\lib gendef.exe libmysql.dll dlltool -v --dllname libmysql.dll --def libmysql.def --output-lib libmysql.lib copy libmysql.dll C:\Ruby200-x64\bin copy libmysql.lib C:\Ruby200-x64\bin

按如下方式安装gem（注意使用正斜杠而不是反斜杠，如果使用反斜杠则会失败）：

gem install mysql2 --platform=ruby -- '--with-mysql-dir="C:/mysql-connector/"'

希望这会有所帮助，希望有人会关注那些想要进行Ruby on Rails开发的少数Windows 7 / 8.1用户。

MySQL2 gem不会安装
