mysql - RoR + XAMPP + MySQL -- Gem 安装 MySQL 问题

Question

我的职业是 PHP 开发人员，我使用 XAMPP。我现在决定深入研究 Ruby，并且想使用 XAMPP for Ruby 中的 MySQL 安装，但在正确安装 Gem for mysql 时遇到问题。

我正在执行的命令是这样的:

sudo gem install mysql -- —–with-mysql-config=/Applications/XAMPP/xamppfiles/bin/mysql_config

我得到的错误是这样的:

Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

make failed, exit code 2

Gem files will remain installed in /Library/Ruby/Gems/2.0.0/gems/mysql-2.9.1 for inspection.
Results logged to /Library/Ruby/Gems/2.0.0/extensions/universal-darwin-14/2.0.0/mysql-2.9.1/gem_make.out
An error occurred while installing mysql (2.9.1), and Bundler cannot continue.
Make sure that `gem install mysql -v '2.9.1'` succeeds before bundling.

如果我定位 mysql_config，我会得到:

/Applications/XAMPP/xamppfiles/bin/mysql_config
/Applications/XAMPP/xamppfiles/bin/mysql_config_editor
/Applications/XAMPP/xamppfiles/man/man1/mysql_config.1
/Applications/XAMPP/xamppfiles/man/man1/mysql_config_editor.1

我已经浏览了 SO 上的所有帮助请求，但找不到针对我的特定问题的解决方案。

如有任何帮助，我们将不胜感激。如果您需要任何进一步的信息，请告诉我。

谢谢!

这对我使用 RubyGems 在 MacOS X High Sierra 上有效:

    gem install mysql2 -- \
        --with-mysql-config=/Applications/XAMPP/xamppfiles/bin/mysql_config \
        --with-mysql-dir=/Applications/XAMPP/xamppfiles/mysql/ \
        --with-mysql-lib=/Applications/XAMPP/xamppfiles/lib/mysql/ \
        --with-mysql-include=/Applications/XAMPP/xamppfiles/include/ \
        --no-ri --no-rdoc
