java 无法在 ubuntu 系统上安装 rJava

Can't install rJava on ubuntu system

提问by h.l.m

I've seen a few posts related to this...but all the suggested solutions ive seen dont seem to work....I am running R in an EC2 instance and ran the following commands to try and install rJava but to no avail...any help would be greatly appreciated.

我看过一些与此相关的帖子......但我看到的所有建议的解决方案似乎都不起作用......我在 EC2 实例中运行 R 并运行以下命令来尝试安装 rJava 但无济于事...任何帮助将不胜感激。

The easiest way to get rJava on Ubuntu is to install it from the repositories instead of trying to install it directly from CRAN. From the command line this should do the trick

在 Ubuntu 上获取 rJava 的最简单方法是从存储库安装它，而不是尝试直接从 CRAN 安装它。从命令行这应该可以解决问题

sudo apt-get install r-cran-rjava

sudo apt-get install r-cran-rjava 

didn't work in R Studio, so I had to use the terminal but then worked perfectly for me.

在 R Studio 中不起作用，所以我不得不使用终端，但后来对我来说完美无缺。
