Question

我有$ ORACLE_HOME和$ LD_LIBRARY_PATH变量

vagrant@oracle:~$ env | grep oracle
LD_LIBRARY_PATH=/u01/app/oracle/product/11.2.0/xe/lib:
ORACLE_BASE=/u01/app/oracle
PATH=/home/vagrant/.rbenv/shims:/home/vagrant/.rbenv/bin:/u01/app/oracle/product/11.2.0/xe/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/opt/vagrant_ruby/bin
ORACLE_HOME=/u01/app/oracle/product/11.2.0/xe

但我仍然无法安装ruby-oci8

这是错误消息

vagrant@oracle:~$ sudo gem install ruby-oci8

Answer 1

确保正确放置这些值：

在.bashrc或.bach_profile中（无论你使用哪个）

ORACLE_HOME=/opt/oracle/12_1/instantclient
LD_LIBRARY_PATH=/opt/oracle/12_1/instantclient

然后到达你的instantclient目录（/ opt / oracle / 12_1 / instantclient）

ln -s libclntsh.so.12.1 libclntsh.so
chmod -R a+rX $ORACLE_HOME or chmod -R 755 $ORACLE_HOME

现在，只要我使用12.1

，您就会看到正确的版本

Answer 2

您似乎正在使用sudo来安装宝石。出于安全原因，sudo显然已取消LD_LIBRARY_PATH。尝试不使用sudo或在sudo运行后重新设置：

sudo LD_LIBRARY_PATH=$LD_LIBRARY_PATH gem install ruby-oci8

Answer 3

我遇到了类似的问题，发现需要gcc >= 4.9。

安装ruby-oci8时出错
