我正在安装 Oracle Instant Client：Basic、SDK 和 SQL*Plus 软件包 v 10.2.0.5。

mkdir /opt
mkdir /opt/oracle
cd /opt/oracle
unzip path/to/instantclient-basic-OS-VERSION.zip
unzip path/to/instantclient-sdk-OS-VERSION.zip
unzip path/to/instantclient-sqlplus-OS-VERSION.zip

之后我设置vim ~/.oracle_client

    export ORACLE_HOME=/opt/oracle/
    export TNS_ADMIN=/admin/network/
    export LD_LIBRARY_PATH="/opt/oracle/instantclient_10_2/"

echo "source ~/.oracle_client" >> ~/.bash_profile source ~/.bash_profile

创建 tnsnames.ora 并测试连接 sqlplus opsvod/agatb137@FESTEST

但是当我尝试安装时gem install ruby-oci8 -v '2.1.5'出现错误：

如何解决这个问题？

我们不会为我们的 Oracle 部署安装 gem，而是从源代码构建：

  1. 确保 ORACLE_HOME 指向 oracle 完整客户端或 oracle instaclient
  2. 确保在 $ORACLE_HOME/lib libclntsh.so 中作为指向 libclntsh.so.11.1 的符号链接存在
  3. 切换到 ruby​​-oci8-2.1.x 目录并运行
    1. 红宝石 setup.rb 配置
    2. ruby setup.rb 设置
    3. 红宝石 setup.rb 安装
  4. 仅在安装 ruby​​-oci8 适配器时安装 activerecord-oracle_enhanced-adapter。

跳过：/opt/oracle/instantclient_10_2/libclntsh.so.10.1 适用于 i386 cpu。

即时客户端是 32 位的。

检查 LP64... 是的

红宝石是 64 位的。

即时客户端的位数必须与 ruby​​ 相同。您需要 64 位即时客户端才能与 64 位 ruby​​ 一起使用。

If you are by any chance trying to install this gem on Fedora 27 and are faced with a very similar error message, try to do:

dnf install rpm-build libnsl*

This fixed my errors (found it here).

EDIT: As of Fedora 28, libnsl* is no longer included as default dependency. This will make the ruby-oci8 gem fail for less than obvious reasons. The install directive above has been updated with this finding.
