通过pip在WSL2上未正确安装Cfgrib

Question

我正在尝试将cfgrib安装到我的WSL2 Ubuntu上，但是当我输入python3 -m cfgrib selfcheck时，它给出了如下错误。

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:

Traceback (most recent call last):
  File "/usr/lib/python3.8/runpy.py", line 184, in _run_module_as_main
    mod_name, mod_spec, code = _get_module_details(mod_name, _Error)

    raise RuntimeError(f"ecCodes library not found using {LIBNAMES}")
RuntimeError: ecCodes library not found using ['eccodes', 'libeccodes.so', 'libeccodes']

我的python版本是Python 3.8.2。可以通过pip安装cfgrib吗？

Answer 1

PyPI doesn't declare eccodes or pyeccodes as a dependency上最新发布的cfgrib版本0.9.8.5，甚至没有额外的版本。您可以单独安装其中一个：

pip install eccodes

或

pip install pyeccodes

(我不知道有什么不同；cfgrib可以use both)。

bug is fixed in the repository，但尚未发布到PyPI，因此您可以尝试使用git安装最新版本

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