[英]Error installing mysql2 gem
我正在嘗試使用 MySQL 設置我的 RubyOnRails 開發環境。 我已經安裝了 XAMPP,所以我決定使用 XAMPP 的 MySQL 安裝,(因此我安裝了 XAMPP 開發包)。
現在我正在嘗試安裝 mysql2 gem,但出現此錯誤:

所以我認為這里的關鍵點是:
ld: -rpath can only be used when targeting Mac OS X 10.5 or later
我嘗試設置 MACOSX_DEPLOYMENT_TARGET=10.6 但沒有任何變化。
順便說一句,我使用的是 Mac OS X 10.6.6,所以上面的錯誤沒有任何意義......
謝謝!
您可以嘗試以下幾種可能性。
嘗試將--platform=ruby
添加到您的命令中。 我看到人們聲稱它有幫助。
你的命令應該是:
gem install mysql2 --platform=ruby --version 0.2.7 -- --with-mysql-dir=/Applications/XAMPP/xamppfiles/ --with-mysql-lib=/Applications/XAMPP/xamppfiles/lib/mysql/ –with-mysql-include=/Applications/XAMPP/xamppfiles/include/mysql/ --with-mysql-config=/Applications/XAMPP/xamppfiles/bin/mysql_config
確保您正在構建正確的架構。 OSX 10.6.x 對何時使用 32 位內容和何時使用 64 位內容非常模糊,至少據我所知。
您需要嘗試針對 MySQL 的 32 位和 64 位版本進行構建。
最簡單的方法是從http://dev.mysql.com/downloads/mysql/#downloads下載它們並嘗試針對每一個進行構建。
