Question

我刚刚将我的RoR dev环境迁移到了Ubuntu。我从github上拉了一个我正在研究的项目，并试图安装所有必要的宝石。但是，每当我运行bundle或bundle install或bundle install exec时，我都会收到以下错误：

Gem files will remain installed in /home/edu/Workspace/SuitBrokers/exec/ruby/1.9.1/gems/mysql-2.8.1 for inspection.

An error occured while installing mysql (2.8.1), and Bundler cannot continue.
Make sure that `gem install mysql -v '2.8.1'` succeeds before bundling.

有没有人处理过这种特殊的疼痛？您的帮助永远受到赞赏。

Answer 1

你需要告诉bundler在你的盒子里找到mysql-dev的东西。通常类似于以下内容将起作用：

bundle config build.mysql --with-mysql-config=/usr/local/mysql/bin/mysql_config

当然，您需要将上面的路径替换为mysql_config的实际路径。如果您没有安装mysql_config，那么您将需要在服务器上安装mysql-dev软件包。看起来你可能在共享服务器上，所以希望已经安装了开发包。如果没有，您需要提出要求。

Answer 2

Ubuntu 14.04（Trusty）上缺少的库是： libmysqlclient-dev 。下面这一行为我做了诀窍：

sudo apt-get install libmysqlclient-dev

我无法运行bundler，不断收到错误
