Question

我执行

$ bundle install

对于我的rails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（尤其是来自这里）做了所有事情。我觉得这个最接近...... http://jigyasamakkar.com/ruby-oci8-with-rails-3-1-on-ubuntu/

解决此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（但对于ubuntu也可以。）完整说明见：

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

抓住以下文件：

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

环境变量说明：

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

要使ruby-oci8正常工作，安装即时客户端，即时客户端SDK和sqlplus即时客户端非常重要。这是一个很好的工具：）

我能在网上找到的最好的资源（像魅力一样）来自help.ubuntu.com，所以这是一个很好的权威资源：

https://help.ubuntu.com/community/Oracle%20Instant%20Client

它使用rpms安装即时客户端，可以通过外星人来完成。无论如何，这里都有解释。

要在代码中连接OCI，请配置TNS_ADMIN环境变量。我将它放在ubuntu社区解决方案中提到的相同位置（在配置ORACLE_HOME的同一位置）。我使用与oracle rdbms中常见的文件夹标准相同的文件：network / admin。

对我来说是： sudo vi /etc/profile.d/oracle.sh export ORACLE_HOME = / usr / lib / oracle / 11.1.0.1 / client export TNS_ADMIN = / usr / lib / oracle / network / admin

然后将你的tnsnames.ora放在TNS_ADMIN文件夹中。

完成后，只需安装gem。

宝石会抛出一些错误/警告，但它们不是很重要，它仍然有效。重新启动会话以获取环境变量。
