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

我正在使用 Ubuntu 14.04.3 和最新版本的 anaconda。

当 pystan 尝试编译模型时,我收到以下错误:

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

当我在工作中尝试在我的 RHEL 服务器上运行模型时,一切正常。

在安装pystan之前,我跑了

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。

我不知道接下来要尝试什么。

编辑:完整的错误输出如下

解答

如果有人有同样的问题,以下步骤解决了问题

1.卸载Anaconda

2.安装蟒蛇

3.使用pip安装pystan

不知道为什么会这样。
