Question

据我了解，有一些与SIP相关的变化使得安装变得困难。

这些页面有安装的背景和建议。 http://sourceforge.net/p/cx-oracle/mailman/message/34534872/，http://stefanoapostolico.com/2015/10/08/install_cx_oracle_with_sip_enabled.html

把所有这些放在一起，这是我最好的把它安装到我的virtualenv，但唉，仍然没有好处。

我得到的错误是：

我在尝试使用Oracle instantclient 12.1 尝试安装cx_Oracle时尝试了上述操作并出现以下错误：

[535]: /opt/instantclient_12_1 $ python -c "import cx_Oracle"
Traceback (most recent call last):
  File "<string>", line 1, in <module>
ImportError: dlopen(/Library/Python/2.7/site-packages/cx_Oracle.so, 2): 
        Library not loaded: @rpath/libclntsh.dylib.12.1
  Referenced from: /Library/Python/2.7/site-packages/cx_Oracle.so
  Reason: image not found

注意错误中的 @rpath - 结果是在El Capitan上构建cx_Oracle库（对于instantclient 12.1）时，gcc编译器需要-rpath标志被设置为知道在哪里找到上述动态链接库（* .dylib）。默认情况下，在instantclient 12.1上， pip 不会为您执行此操作。

# Set -rpath option before installing...this will use $ORACLE_HOME during compilation
export FORCE_RPATH=TRUE
pip install cx_Oracle
# And verify cx_Oracle was correctly installed
python -c "import cx_Oracle"
# If this line fails install cx_Oracle with:
#   pip install --no-cache-dir --allow-external --allow-unverified cx_oracle

python -c "import cx_Oracle"应该报告没有错误。

Answer 2

感谢Greg的指示。

我必须为我的cx_Oracle pip install创建一个符号链接（使用上面提供的参数）。您可能希望将这些添加到您的说明中。

ln -s libclntsh.dylib.11.1 libclntsh.dylib

我还根据本安装指南中的建议为libocci创建了另一个链接：https://gist.github.com/thom-nic/6011715

ln -s libocci.dylib.11.1 libocci.dylib

Answer 3

我想我修好了。基本上我上面发布的所有步骤都是正确的。

但我最终使用它来进行pip安装，以确保它下载一个新副本并重建（并且可能会获得更高版本？）

$ pip install --no-cache-dir --allow-external --allow-unverified cx_oracle

然后我可以毫无问题地导入cx_oracle，但是当连接到外部服务器时，我收到错误“'ORA-21561：OID生成失败'。”

然后我跟着instructions here并在/ etc / hosts文件中添加了一个带有主机名的行，现在一切正常。

例如，在/ etc / hosts

的末尾添加了这样的行

127.0.0.1 localhost my-host-name

Answer 4

要在OS X上安装cx_Oracle，请下载64位Instant Client basic＆amp;来自http://www.oracle.com/technetwork/topics/intel-macsoft-096467.html的OS X的sdk包。使用此版本的Instant Client，您可以连接到10g，11g和12c数据库。此版本的链接方式可以避免Apple最近引入的SIP问题（影响Instant Client 11.2）。

然后运行类似：

unzip instantclient-basic-macos.x64-12.1.0.2.0.zip
unzip instantclient-sdk-macos.x64-12.1.0.2.0.zip
cd instantclient_12_1
ln -s libclntsh.dylib.12.1 libclntsh.dylib
cd ..
export ORACLE_HOME=`pwd`/instantclient_12_1
export FORCE_RPATH=1
pip install cx_Oracle

您可能需要或不需要其他pip选项，如https://stackoverflow.com/a/33284974/4799035

中所述

Answer 5

另请注意：如果您的python运行为32位，并将cx_Oracle安装为64位，您也将遇到此问题。要避免此问题，请始终以超级用户的身份运行您的命令＆＃39; su＆＃39;并清楚地了解＆＃39; su＆＃39; python是32位或64位。检查你的python位How do I determine if my python shell is executing in 32bit or 64bit mode on OS X?

强制使用64位运行：

arch -x86_64 / usr / bin / python27

强制使用32位运行：

默认写入com.apple.versioner.python Prefer-32-Bit -bool yes
