在 Red Hat Enterprise Linux 服务器版本 6.10（圣地亚哥）上构建 MultiNest 时安装失败

Question

在按照设置说明安装 PyMultiNest 的过程中，我遇到了障碍。以下是我遵循的步骤顺序，但在构建库（第 2 步）时失败了，并且出现了以下错误：

(envsam) [user@comp-ic-0018 build]$ module unload

You should consider upgrading via the 'pip install --upgrade pip' command.

这 post 建议使用 gfortran 6 或 7。我也在做同样的事情，但仍然遇到错误。

寻求帮助解决这个问题。
