Mac OSX Sierra Python 3.5.2 cx_oracle安装失败

Question

我正在尝试使用cx_Oracle模块将Python与我的Oracle数据库连接。 我尝试在最近几个小时内安装它，但找不到我的问题的答案。

使用以下命令安装cx_oracle时： pip install cx_oracle

我收到这种错误消息。 我遵循了10多个教程，但似乎找不到答案。 设置正确的环境变量，其他所有工作。

好的，所以我发现了错误：

在我的情况下，转到您的$ORACLE_HOME是/ library / oracle / instantclient_11_2

ln -s libclntsh.dylib.12.1 libclntsh.dylib

接着

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

为我工作。
