mysql - Ruby - Gem - mysql - 无法构建 gem native 扩展

Question

两天以来我遇到了一个无法解决的问题。我正在尝试在 debian 机器上安装 redmine。当安装 gem mysql 时，它失败了。我不知道该怎么办了。我的最后一个例子是你的帮助。

错误

What I've tried

• Installing packages by instruction: http://wiki.rubyonrails.org/database-support/mysql#linux_ubuntu
• installing with mysql_config parameter
  root@host:~# find / -name mysql_config
  /usr/bin/mysql_config
  root@host:~# gem1.8 install mysql -- --with-mysql-config=/usr/bin/mysql_config

Answer 1

看来您走在正确的道路上。即使您看起来已经安装了 mysql 库，您也需要确保 MySQL 开发头文件及其依赖项已完全安装，以便编译 MySQL gem。

尝试:

sudo apt-get install mysql-dev

然后:

sudo gem install mysql -- --with-mysql-config=/usr/local/mysql/bin/mysql_config

显然，确切的命令取决于 mysql-dev 文件的安装位置。
