安裝mysql2時出錯

我想在服務器上安裝mysql2。所以我的第一個倒黴的線索是如下安裝mysql2時出錯

gem install mysql2

輸出

Gem files will remain installed in /home/aaalsubaie/.gems/gems/mysql2-0.3.11 for inspection. 
Results logged to /home/aaalsubaie/.gems/gems/mysql2-0.3.11/ext/mysql2/gem_make.out

這並不是故事的結尾

運行後

[ps89405]$ mysql --help | grep Default -A 1 
Default options are read from the following files in the given order: 
/etc/my.cnf /etc/mysql/my.cnf /usr/etc/my.cnf ~/.my.cnf

我試圖

gem install mysql2 -- --with-mysql-config=~/.my.cnf --ruby=/usr/bin/ruby1.8

和

gem install mysql2 -- --with-mysql-config=/usr/etc/my.cnf --ruby=/usr/bin/ruby1.8

和

gem install mysql2 -- --with-mysql-config=/etc/my.cnf --ruby=/usr/bin/ruby1.8

沒有運氣同樣的錯誤。

我不跑RVM

和我的寶石ENV是

RubyGems Environment: 
    - RUBYGEMS VERSION: 1.3.7 
    - RUBY VERSION: 1.8.7 (2010-08-16 patchlevel 302) [x86_64-linux]

這是我上排第二天嘗試沒有運氣我部署我的第一個Rails應用程序，雖然它會容易得多。

更新：

現在命令工作，mysql2寶石感謝醃好

gem install mysql2 -- --with-mysql-config=/usr/bin/mysql_config

安裝我現在有新的問題與mysql2寶石當我運行

bundle exec rails console

的命令應該是這樣的：

gem install mysql -- --with-mysql-config=/usr/local/mysql/bin/mysql_config

選項「具有MySQL的-配置」指的不是配置文件的「mysql_config」工具。

而你最好是mkmf.log文件。

/usr/local/mysql/bin /在我的服務器中不存在！我也不理解你的最後一行。 – aaalsubaie 2012-04-11 09:30:01

感謝它安裝開發庫後工作。我現在有新的問題可以閱讀我對上述問題的更新。 – aaalsubaie 2012-04-11 10:00:15

又一個'捆綁安裝'？ – Reactormonk 2012-04-11 10:07:41

這可能不是給你直接的關係，但我面對完全相同的問題，我想我的回答可以幫助其他有此問題：

sudo apt-get install libmysql-ruby 
sudo apt-get install libmysqlclient-dev 
sudo gem install mysql2

爲我工作。

如果你在Mac上，安裝MySQL自制brew install mysql，那應該讓你安裝gem後。

首先，你必須運行此命令：

sudo apt-get install libmysqlclient-dev

然後你就可以運行這個命令：

gem install mysql2

它應該是工作..

sudo易於得到安裝libmysqlclient-dev 系統會安裝其他兩個lib： mysql -common libmysqlclient16

「bundle exec rails console」針對捆綁器的Gemfile運行，但是您使用rubygems安裝了mysql2。你需要運行：

gem uninstall mysql2    # uninstall mysql2 from system 
bundle exec gem uninstall mysql2 # uninstall mysql2 from bundler 
bundle config build.mysql2 --with-mysql-config=/usr/bin/mysql_config # set build option for mysql2 gem 
bundle install     # reinstall mysql2 
bundle exec rails console   # start rails console using the rails exec installed via bundler

額外注：如果您使用的乘客，您只需更新你的Ruby版本，確保乘客重新安裝和更新你的httpd.conf，以便成功地啓動服務器。
