我一直试图将rJava加载到我的RStudio设置中，但是它根本无法正常工作.使用命令library(rJava)时，它可以很好地安装但不会加载.

2. 我尝试将JAVA_HOME环境变量更改为jdk位置.
3. 我已经尝试了中的所有内容一样，但是没有用.

1. I have installed the latest version of jdk which is jdk 9.0.1.
2. I have tried changing the JAVA_HOME environment variable to the jdk location.
3. I have tried everything in this question as well but it didn't work.

推荐答案

要使rJava在Macbook上工作，必须采取一系列非常具体的步骤，如 rJava问题#86 .

There is a very specific sequence of steps that must be taken to get rJava to work on a Macbook, as documented in rJava Issues #86.

1. 从Oracle下载并安装Java
2. 卸载任何以前安装的rJava版本
3. 将JAVA_HOME添加到您的.bashrc
4. 关闭&重新启动终端，R和RStudio会话，以便它们接收更新的JAVA_HOME
5. 使用install.packages()安装rJava

1. Download and install Java from Oracle
2. Uninstall any previously installed version of rJava
3. Add JAVA_HOME to your .bashrc
4. Close & restart terminal, R and RStudio sessions so they pick up the updated JAVA_HOME
5. Use install.packages() to install rJava
