peer包安装

conda create --name peer python=3.5.4; conda activate peer
conda config --add channels conda-forge
conda config --add channels r
conda install zlib=1.2.8
conda install r=3.4.1
conda install r-peer;#这一步无法进行，得用安装包

wget https://raw.githubusercontent.com/broadinstitute/gtex-pipeline/master/qtl/R_peer_source_1.3.tgz
R CMD INSTALL R_peer_source_1.3.tgz
