mysql - MacOS 10.14 安装和 brew 更新后无法安装 mysql gem

coder 2023-10-09 原文

安装 macOS 10.14 + Brew 更新后我的开发系统坏了。

我无法安装 mysql gem。尝试安装时我得到:

$ gem install mysql -v '2.8.1' --source 'http://rubygems.org/'
Building native extensions.  This could take a while...
ERROR:  Error installing mysql:

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:

    --without-opt-dir
    --with-opt-include

To see why this extension failed to compile, please check the mkmf.log which can be found here:

我通过 Brew 安装了 mysql 并保持 mysql、mysql@5.6 或 mysql@5.7 处于事件状态。路径在 .bash_profile 中设置:

### Customize path for MYSQL
MYSQL=/usr/local/mysql/bin
export PATH=$PATH:$MYSQL
export DYLD_LIBRARY_PATH=/usr/local/mysql/lib:$DYLD_LIBRARY_PATH

当我切换到 mysql@5.6 或 5.7 时，我会相应地更改路径。 一般情况下，mysql 似乎存在一些问题。

当一个使用 Ruby 1.8.7、Rails 3.2.5 和 mysql 数据库的 webapp 正在运行时，另外两个具有相同技术栈的 webapp 无法重新安装 mysql gem 或连接到数据库。

有人能帮忙吗？

最佳答案

Mojave 更改了编译 C 扩展所需的头文件的位置。您可能需要运行以下命令来安装 mysql gem:

sudo installer -pkg /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg -target /
