无法在Ubuntu 12.04LTS上安装ruby-oci8

Question

我执行

$ bundle install

对于我的导轨应用程序......(3.2.8)

当它到达ruby-oci8时...

An error occurred while installing ruby-oci8 (2.1.5), and Bundler cannot continue.
Make sure that `gem install ruby-oci8 -v '2.1.5'` succeeds before bundling.

我从每个网站和论坛(特别是从这里)做了一切.这个我觉得最近的... http://jigyasamakkar.com/ruby-oci8-with-rails-3-1-on-ubuntu/

解决这个问题的最佳方法是什么？

Answer 1

我最近不得不安装oracle + ruby​​ gem,这里是mac的说明(但是对于ubuntu也可以.)完整说明如下:

http://blog.codiez.co.za/2013/09/setup-oracle-instant-client-ruby-oci8-gem-mac/

关键是ruby-oci gem需要知道动态库的存储位置.对于ubuntu,您需要设置:LD_LIBRARY_PATH

抓取以下文件:

• instantclient-basic-linux.x64-11.2.0.3.0.zip
• instantclient-sqlplus-linux.x64-11.2.0.3.0.zip
• instantclient-sdk-linux.x64-11.2.0.3.0.zip

提取它们并将它们放在某处,然后添加以下环境变量.有关详细说明,请参阅链接

export ORACLE_BASE=/usr/local/oracle
export ORACLE_HOME=$ORACLE_BASE/product/instantclient_64/11.2.0.3.0
export PATH=$ORACLE_HOME/bin:$PATH
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:$DYLD_LIBRARY_PATH
export TNS_ADMIN=$ORACLE_BASE/admin/network

环境变量的说明:

ORACLE_BASE:存储所有文件的位置 ORACLE_HOME:实际客户端LD_LIBRARY_PATH的路径 :应该指向lib目录,确保你在这里提取了SDK zip文件 TNS_ADMIN:在哪里找到你的TNS_ADMIN文件(对ruby来说不是必需的) oci gem)
