Question

我刚刚负责新的应用程序，已经构建的应用程序，以添加新的功能等。不幸的是，它是几年前建立的（使用rails 2.1）并使用mysql（我更喜欢postgres）。我试图安装mysql gem所以我可以搞乱我的本地机器上的代码，我收到以下错误。

$ sudo env ARCHFLAGS="-arch i386" gem install mysql -- --with-mysql-config=/usr/local/mysql/bin/mysql_config
Password:
Building native extensions.  This could take a while...
ERROR:  Error installing 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.

Provided configuration options:
    --with-opt-dir
    --with-opt-include
    --without-opt-include=${opt-dir}/include
    --with-opt-lib
    --without-opt-lib=${opt-dir}/lib
    --with-make-prog
    --without-make-prog
    --srcdir=.
    --curdir
    --ruby=/opt/local/bin/ruby
    --with-mysql-config


Gem files will remain installed in /opt/local/lib/ruby/gems/1.8/gems/mysql-2.8.1 for inspection.
Results logged to /opt/local/lib/ruby/gems/1.8/gems/mysql-2.8.1/ext/mysql_api/gem_make.out

我检查了目录/ usr / local / mysql / bin / mysql_config以确保文件存在（确实存在）...我从mysql站点安装了带有dmg文件（v 5.1）的mysql。

坦率地说，我不知道如何解决这个问题。有什么建议吗？

谢谢！

Answer 1

我认为dmg文件中不包含mysql头文件。安装Homebrew或Macports并运行brew install mysql或sudo port -v install mysql5-server mysql5

rails中的mysql gem install错误
