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

import cfgrib

这是完整的错误消息

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

如 pypi ( https://pypi.org/project/eccodes/ ) 所述，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
