我在我的機器上安裝mysql2 gem時遇到了問題。如何在Ruby 1.9.3下安裝mysql2 gem?在2.0.0下工作
我有OS X 10.8與最新的Xcode和mySql通過Homebrew安裝。所有使用最新RVM安裝的紅寶石。
我可以在安裝紅寶石精細mysql2 2.0.0-P195
[~]$ rvm use 2.0.0 [ruby-1.9.3-p429]
Using /Users/aselder/.rvm/gems/ruby-2.0.0-p195
[~]$ gem in mysql2 [ruby-2.0.0-p195]
Fetching: mysql2-0.3.11.gem (100%)
Building native extensions. This could take a while...
Successfully installed mysql2-0.3.11
1 gem installed
下的Ruby 1.9.3和1.8.7,它無法找到的mysql.h文件
[~]$ rvm use 1.9.3 [ruby-1.9.3-p429]
Using /Users/aselder/.rvm/gems/ruby-1.9.3-p429
[~]$ gem in mysql2 [ruby-1.9.3-p429]

necessary libraries and/or headers. Check the mkmf.log file for more
details. You may need configuration options.

我也嘗試了各種命令行選項來獲取gem來查找mysql安裝:
eg 創業板安裝mysql2 - --with-mysql的-配置=在/ usr /本地/選擇/ MySQL的/斌/ mysql_config
我有這個完全相同的問題,我一直沒能弄清楚 – vanhowen
我有完全相同的問題。我在一臺全新的機器上(10.8)。 Ruby 2.0的工作沒有問題,1.9.2和1.9.3抱怨缺少mysql.h。 – fflyer05
你的MySQL版本是什麼?我使用5.6.12也遇到了同樣的問題。卸載它並安裝5.6.10解決了這個問題。 –
