Issue Installing MRAID about mraid

[yuanzhongshang]

Hello,
Thanks for your interest with the MRAID method. From your error message, we speculate you are using a mac system. Under mac system, you need to install gfortran in -L/usr/local/gfortran/lib/gcc/x86_64-apple-darwin18/8.2.0 according to the error message. You can perform the following steps on the mac terminal to solve the issue.
Step1: install brew
Step2: install gcc
brew install gcc
Step3: create a new path
sudo mkdir -p /usr/local/gfortran/lib/gcc/x86_64-apple-darwin18/8.2.0
Step4: copy gcc from step2 to the path in step3
sudo cp /usr/local/Cellar/gcc/9.2.0_3/lib/gcc/9/* /usr/local/gfortran/lib/gcc/x86_64-apple-darwin18/8.2.0
(where /usr/local/Cellar/gcc/9.2.0_3/lib/gcc/9/* is the path of gcc including gfortran)
Step5: install MRAID
# install.packages("devtools")
library(devtools)
install_github("yuanzhongshang/MRAID")
