这是我之前一篇关于在 Mac 上使用 R 和 JAVA 的后续文章。我的应用程序依赖于 R 来运行。我已经安装了 Java，Java 版本“1.6.0_37”。我已经安装了“R”，R 版本 2.15.1。现在我需要包含在rJava中的 JRI 。

在 R 内部，我运行了以下命令

install.packages('rJava',,' http: //www.rforge.net/ ')

这是输出：

install.packages('rJava',,'http://www.rforge.net/')
trying URL 'http://www.rforge.net/bin/macosx/leopard/contrib/2.15/rJava_0.9-4.tgz'
Content type 'application/x-gzip' length 506489 bytes (494 Kb)
opened URL
==================================================
downloaded 494 Kb


The downloaded binary packages are in
    /var/folders/gz/1jwm65h12132yq8_1wdsl9cr0000gn/T//RtmpGHpTYR/downloaded_packages

我从这里去哪里？

启动tomcat时出现以下错误：

Cannot find JRI native library!
Please make sure that the JRI native library is in a directory listed in java.library.path.

更新 2/15/13 尝试设置环境变量后...

我自己的路：

    DAVIDs-MacBook-Pro-2:~ dave$ echo $PATH
/opt/local/bin:/opt/local/sbin:/usr/local/rvm/gems/ruby-1.9.3-p194/bin:/usr/local/rvm/gems/ruby-1.9.3-p194@global/bin:/usr/local/rvm/rubies/ruby-1.9.3-p194/bin:/usr/local/rvm/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/opt/X11/bin:/usr/local/git/bin:/opt/sm/bin:/opt/sm/pkg/active/bin:/opt/sm/pkg/active/sbin:/usr/local/mysql/bin:/usr/libexec/java_home:/Library/Frameworks/R.framework/Versions/2.15:/Library/Frameworks/R.framework/Versions/2.15/Resources/library/rJava/jri

环境变量

JAVA_HOME 位置

R_HOME 和 JRI 位置

仍然收到上面的错误。

确保运行 Tomcat 的用户的环境变量存在。
