无法安装do_mysql gem？

Question

我正在尝试在我的Snow Leopord系统Macbook Pro 13上安装do_mysql,但我不断收到此错误:

n216-160:~ myself$ sudo gem1.9 install do_mysql
Password:
Building native extensions.  This could take a while...
ERROR:  Error installing do_mysql:
    ERROR: Failed to build gem native extension.

Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers.  Check the mkmf.log file for more
details.  You may need configuration options.

我不知道为什么.我还用MySQL 5.4.3测试版重新安装了我的MySQL版本,64位正如其他人所建议但没有骰子.有谁知道什么是错的？

Answer 1

您缺少libmysqlclient-dev软件包.在Deb系统上,你可以使用它来安装它

sudo apt-get install libmysqlclient-dev

不确定mac(也许是"sudo port install libmysqlclient-dev"？)

Answer 2

我有同样的问题,上面的解决方案没有工作,直到我修复我的$ PATH:PATH ="/ usr/local/bin:/ usr/local/sbin:$ PATH"#如果还没有出现PATH ="$ PATH :/ usr/local/mysql/bin"export PATH = $ PATH

Answer 3

sudo env ARCHFLAGS="-arch x86_64" gem install do_mysql -- --with-mysql-dir=/usr/local/mysql/

Answer 4

尝试这个

sudo env ARCHFLAGS="-arch x86_64"
gem install do_mysql --with-mysql-dir=/usr/local/mysql/ --ruby=/opt/local/bin/ruby1.9

你必须指定 mysql 安装的位置，以及 ruby​​ 安装的位置，因为你使用的是 ruby​​1.9，我假设你的机器上可能也运行着 1.8。
