pystan:distutils.errors.CompileError:命令"gcc"失败，退出状态为1

问题描述

我正在使用Ubuntu 14.04.3和最新版本的anaconda.

I'm using Ubuntu 14.04.3 and latest version of anaconda.

当pystan尝试编译模型时，出现以下错误:

When pystan tries to compile models, I get the following error:

distutils.errors.CompileError: command 'gcc' failed with exit status 1

当我尝试在工作的RHEL服务器上运行模型时，一切正常.

When I try running the models on my RHEL server at work, everything works fine.

在安装pystan之前，我已经运行

Before installing pystan, I ran

apt-get install build-essential

我尝试使用anaconda安装stan并从源代码构建，但仍然出现错误.

I've tried installing stan using anaconda and building from source, and I still get the error.

我不知道下一步该怎么做.

I have no idea what to try next.
