本人菜鸟，花了一周的时间，在ubuntu10.04上安装成功了redmine1.4，今天在要公司的服务器（ubuntu12.04）上安装，可是当执行bundle install --without development test postgresql sqlite rmagick这一步时出现了：

Make sure that `gem install mysql -v '2.8.1'` succeeds before bundling.

望各位大神们帮个忙解决一下啊。谢谢各位了。

没装ruby那个安装工具gem?

枫叶饭团 写了：没装ruby那个安装工具gem?

我装了呢，rubygems是1.7.2的，在这之前的步骤中我就是用gem install rails -v 2.3.14语句安装rails的。

Check whether libmysqlclient-dev is installed .


應該是這個「libmysqlclient-dev」套件沒有安裝...

===================================================================================
另外
pg(postgresql)好像也會出現，
An error occurred while installing pg (0.14.1), and Bundler cannot continue.
Make sure that `gem install pg -v '0.14.1'` succeeds before bundling.

也是要編譯時，少了dev的套件
可以看下面檔案的訊息
gems/pg-0.14.1/ext/gem_make.out

會發現這一行
You need to install postgresql-server-dev-X.Y for building a server-side extension or libpq-dev for building a client-side application.

$ sudo apt-get install postgresql-server-dev-all libpq-dev


sqlite3也會
An error occurred while installing sqlite3 (1.3.6), and Bundler cannot continue.
Make sure that `gem install sqlite3 -v '1.3.6'` succeeds before bundling.

gems/sqlite3-1.3.6/ext/sqlite3/gem_make.out

$ sudo apt-get install libsqlite3-dev

以此類推....
看gem_make.out，查出少了哪個develop套件，因為編譯需要，
安裝他，就可以解決了
Ubuntu底下的develop套件，通常都是lib開頭，dev結尾，很有一致性，沒有就只好求搜尋大神

應該是沒有安裝「libmysqlclient-dev」

$ sudo apt-get install libmysqlclient-dev

應該就OK了

谢了，我已经解决了，不过我现在忘了是怎么解决的。
