fail to install RcppEigen and ClusterProfiler

[aaa20023003]

Dear Eddelbuettel,
I have just met a problem with RcppEigen installation and thus leading to failure of install ClusterProfiler in R studio of Centos 7.4 system on Tencent Cloud.
I was wondering if you could employ any spare time on this issue, and attached �.txt document is the error reports of whole process.

r studio-clusterprofiler.txt

The g++: internal compiler error: Killed (program cc1plus) has been seen before in the past on machines with insufficient memory. If this is a cloud instance, try increasing your RAM.

Thanks for your prompt reply!
I refer the trick as follows to increase the swap space.

sudo dd if=/dev/zero of=/swapfile bs=64M count=16
sudo mkswap /swapfile
sudo swapon /swapfile

After compiling, you may wish to shut the swap space down: 
sudo swapoff /swapfile
sudo rm /swapfile
