Cfgrib没有通过pip正确安装在WSL2上

Question

我正在尝试将cfgrib安装到我的WSL2 Ubuntu中，但是当我输入python3 -m cfgrib selfcheck时，它给出了以下错误:

Traceback (most recent call last):
File "/home/berke/.local/lib/python3.8/site-packages/cfgrib/messages.py", line 42, in <module>
import pyeccodes.compat as eccodes
ModuleNotFoundError: No module named 'pyeccodes'
During handling of the above exception, another exception occurred:

RuntimeError: ecCodes library not found using ['eccodes', 'libeccodes.so', 'libeccodes']

python版本是Python 3.8.2。是否可以通过pip安装cfgrib ?

Answer 1

PyPI最新发布的cfgrib版本0.9.8.5没有将eccodes或pyeccodes声明为依赖项，甚至不是额外的。您可以单独安装其中一个:

pip install eccodes

或

pip install pyeccodes

(我不知道有什么区别;cfgrib可以同时使用).

这个错误已经在仓库中修复了，但还没有发布到PyPI，所以你可以尝试使用git安装最新版本:

pip install --upgrade "git+https://github.com/ecmwf/cfgrib.git#egg=cfgrib"
