无法导入cfgrib

Question

每当我尝试导入cfgrib时，它都会给我一个运行时错误，即它无法加载ecCodes库

import cfgrib

这是完整的错误信息

我已经通过pip 安装了cfgrib和ecCodes

cfgrib                 0.9.9.1             
eccodes                1.4.0               
eccodes-python         0.9.9

Answer 1

如pypi上所述(https://pypi.org/project/eccodes/)eccodes-python包依赖于eccodes系统库。根据错误消息，您没有安装它。

使用conda:安装它可能是最简单的

conda install -c conda-forge eccodes
