/env/py3.6/pkgs/gcc_49-4.9.1-6/bin/../libexec/gcc/x86_64-unknown-linux-gnu/4.9.1/cc1plus: error while loading shared libraries: libcloog-isl.so.4: cannot open shared object file: No such file or directory
error: command 'gcc' failed with exit status 1
conda install cloog 就解决了
需要先source 装了gcc4.9的环境在安装
