python - 在Red Hat Enterprise Linux Server版本6.10(圣地亚哥)上构建MultiNest时，安装失败

Question

在按照安装说明安装PyMultiNest的过程中，我遇到了障碍。这是我遵循的步骤顺序，但是在构建库(步骤2)时失败了，并且出现了以下错误:

(envsam) [user@comp-ic-0018 build]$ module unload   
(envsam) [user@comp-ic-0018 build]$ module load gcc/7.3.1

You are using pip version 9.0.1, however version 20.0.2 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

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

寻求帮助以解决此问题。
