我正在尝试为我从 github 分叉的 rails 应用程序安装所有依赖项。我需要的宝石之一是gem install mysql2 -v '0.3.11'. 但是，尝试运行此程序时出现错误。我几乎不知道从哪里开始这个输出：

Robert-Quinns-MacBook-Pro:talk_your_game robertquinn$ gem install mysql2 -v '0.3.11'

尝试这样安装：

sudo gem install mysql -v '0.3.11' -- —–with-mysql-config=/usr/local/mysql/bin/mysql_config

用您的 mysql_config 路径替换路径。如果您不知道它的位置，您可以尝试：

sudo find / -name mysql_config

您可能没有所需的库。这适用于 Debian/Ubuntu：

sudo apt-get install libmysql-ruby libmysqlclient-dev

我不确定Mac OS。

看看“ Ruby gem mysql2 install failed ”。
