Prophet: "error: command 'gcc' failed with exit status 1" with pystan 2.19 on travis/docker
Installing fbprophet on Travis is currently failing with "error: command 'gcc' failed with exit status 1" when pystan 2.19 is installed. @Gypsying pointed out in #326 that this can is mitigated by setting pystan<=2.18.1.
I'm not able to reproduce this locally yet (on Fedora 29) and am not sure what is the source, or the fix to get it working with pystan 2.19.

@MGES not yet, still not certain what the issue is.

The issue here is that by default travis runs on an old distribution of Ubuntu that uses GCC 4.8.4.
GCC 4.8.4 does not support C++14, and Stan 2.19 requires C++14.
In https://github.com/facebook/prophet/commit/a6a58646869b9e79448e64b308e143be4de26c35 I updated our travis configuration to use Ubuntu Xenial, which uses GCC 5.4.0 and does support C++14. The package now installs without error.

Adding a brief note to help others who land here, because this issue helped me as well. I'm stuck on an earlier gcc (4.4.6) and the 2.18.1 version of pystan still gave the same symptoms as above, but 2.14 appears to work.

I can confirm that PyStan 2.14 works with earlier gcc (4.*) in the Amazon Linux AMI, in case someone has problems there.
