Question

我正在尝试安装我已经从github分离的rails应用程序的所有依赖项。我需要的宝石之一是gem install mysql2 -v '0.3.11'。但是，我在尝试运行时遇到错误。我几乎不知道从哪里开始输出：

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

有什么想法吗？

Answer 1

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 failing”。

Answer 2

尝试以这种方式安装：

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

用mysql_config路径替换路径。如果您不知道它的位置，可以尝试：

sudo find / -name mysql_config

似乎无法安装
