我正在尝试安装 ROracle。由于 ROracle 需要 Oracle OCI 库，我从 Oracle 网站下载了这些文件：instantclient-basic-macos.x64-12.2.0.1.0、instantclient-sdk-macos.x64-12.2.0.1.0.zip。我将这些文件放入 ~/Library/Caches/Homebrew 并使用自制软件安装它们。

brew install instantclient-basic
brew install instantclient-sdk

Oracle 网站也提到需要设置一些环境变量，所以我把它放在我的 .bashrc 文件中：

export LD_LIBRARY_PATH=/usr/local/Cellar/instantclient-basiclite/12.2.0.1.0/lib:$LD_LIBRARY_PATH
export DYLD_LIBRARY_PATH=/usr/local/Cellar/instantclient-basiclite/12.2.0.1.0/lib:$DYLD_LIBRARY_PATH
export NLS_LANG=UTF8

但是尝试在 R 中安装 ROracle 会导致：

> install.packages("ROracle")
Installing package into ‘/usr/local/lib/R/3.4/site-library’
(as ‘lib’ is unspecified)
trying URL 'https://cran.rstudio.com/src/contrib/ROracle_1.3-1.tar.gz'

Warning in install.packages :

R 说它找不到 OCI 库。到目前为止，Oracle 的文档已被证明在解决此问题方面不存在或毫无价值，但我在互联网上发现了一条看起来很有希望的评论。所以我把它写到我的 .bashrc 中并运行它：

R CMD INSTALL --configure-args='--with-oci-lib=/usr/local/Cellar/instantclient-basic/12.2.0.1.0/lib --with-oci-inc=/usr/local/Cellar/instantclient-sdk/12.2.0.1.0/lib/sdk/include' ROracle_1.3-1.tar.gz

有了这个结果：

那么 libons.dylib 有什么问题吗？我应该如何处理这些信息？

macOS 的 Instant Client 12.2 已修补。从http://www.oracle.com/technetwork/topics/intel-macsoft-096467.html获取并解压缩，例如到~/instantclient_12_2

我能够在 macOS 上安装 ROracle：

brew install R

更新库中的 rpath（使用正确的 R 版本号）：

install_name_tool -add_rpath ~/instantclient_12_2 /usr/local/Cellar/r/3.4.3/lib/R/bin/exec/R

运行“R”，然后：

install.packages("DBI")

从https://cran.r-project.org/web/packages/ROracle/index.html下载 ROracle_1.3-1.tar.gz并安装它：

R CMD INSTALL --configure-args='--with-oci-lib=/Users/cjones/instantclient_12_2  --with-oci-inc=/Users/cjones/instantclient_12_2/sdk/include' ROracle_1.3-1.tar.gz

可以在适用于 Windows 和 Mac OS 的 Intall ROracle 软件包中-add_rpath找到解决方案

我使用 Macports 的 R，我做到了：

cd /opt/local/Library/Frameworks/R.framework/Resources/lib
sudo ln -s ~/Applications/instantclient/libclntsh.dylib.12.1
sudo ln -s ~/Applications/instantclient/libclntshcore.dylib.12.1
sudo ln -s libclntsh.dylib.12.1 libclntsh.dylib
sudo ln -s libclntshcore.dylib.12.1 libclntshcore.dylib

我认为libclntsh.dylib.12.1' is needed. But it does not harm to create the others as well. This way you do not need to run每次升级到 R 后只有指向 install_name_tool的链接。

创建链接后，我能够使用安装 ROracleR CMD INSTALL
