在AWS EC2实例上安装rJava软件包 [英] Install rJava package on AWS EC2 instance

问题描述

我在AWS EC2实例上使用R.我正在尝试使用"mailR"包发送邮件.

I am using R on AWS EC2 instance. I am trying to send a mail using the "mailR" package.

有人告诉我要安装该软件包，我之前应该先将其安装为"rJava"，因为"mailR"取决于该软件包.

I was told that to install the package I should previously install the package "rJava" as "mailR" depends on it.

尝试安装"rJava"时出现此错误:

When trying to install "rJava" I get this error:

gcc:错误:libgomp.spec:没有这样的文件或目录

gcc: error: libgomp.spec: No such file or directory

快速搜索后，我在此链接上看到了一篇帖子，对此进行了解释:

After a quick search, I saw a post on this link explaining this:

"您必须确保GCC启用了OpenMP支持.确保在安装时从可选软件包中选择OpenMP."

"You have to make sure your GCC has OpenMP support enabled. Make sure you select OpenMP from the optional packages when installing."

我真的不知道该怎么做.应该在install.packages("rJava")参数中添加一些内容吗?

I really have no idea how to do this. Should it be something to add in the parameters of install.packages("rJava")?

非常感谢您的帮助！

推荐答案

找到了解决方案我确实安装了gcc，但显然我们不应该安装最新版本，因此，如链接文章中所建议，我下载了版本4，并且可以正常工作.

I did install gcc but apparently we should not install the latest version, so as suggested in the linked post, I downloaded version 4 and it worked.

您可以通过输入Putty来做到这一点:

You do that by typing in Putty:

sudo yum install gcc-4.8.5

谢谢！
