无法在macOS Sierra上安装mysql2 gem
无法在macOS Sierra上安装mysql2 gem
提问于 2016-09-21 21:19:47
我正在新的macOS Sierra中设置我的开发环境。
首先，我安装了Ruby Rbenv，Ruby (2.3.1)，Homebrew和最新版本的MySQL (5.7.15)。
$ brew install mysql
$ mysql.server start好了，MySQL已经初始化了。是时候安装mysql2 gem了...
$ gem install mysql2 -- --with-mysql-config=/usr/local/Cellar/mysql/5.7.15/bin/mysql_config但它并没有起作用。
Building native extensions with: '--with-mysql-config=/usr/local/Cellar/mysql/5.7.15/bin/mysql_config'
This could take a while...

Dont know how to set rpath on your system, if MySQL libraries are not in path mysql2 may not load

我只是遇到了同样的问题，尝试了上面列出的所有解决方案，然后开始用头撞键盘几个小时。
然后我想尝试安装/重新安装Xcode命令行工具：
xcode-select --install一旦我这样做了，mysql2 gem安装就没有问题了。我希望这能起到作用！

有很多很棒的答案，我可以把它们组合成这样：
gem install mysql2 --source 'https://rubygems.org/' -- --with-ldflags=-L/usr/local/opt/openssl/lib --with-cppflags=-I/usr/local/opt/openssl/include因为我和bundle config在一起不舒服

我在这里分享我的解决方案，因为其他答案都不起作用。
对于我的环境，我需要MySQL 5.6，所以我必须使用：
用brew install mysql56代替brew install mysql
安装mysql2 gem的捆绑包一直失败，直到：
brew link mysql56
之后我还跑了一次：
mysql.server start
最后一步可能是不必要的，但只需以防万一。
