【问题描述】：

我正在尝试通过它的安装页面安装 Metview 包：

https://anaconda.org/conda-forge/metview

使用代码：conda install -c conda-forge metview

我遇到了这个问题：

(base) C:\Users\Saeed>conda install -c conda-forge metview
Collecting package metadata (current_repodata.json): done
Solving environment: failed with initial frozen solve. Retrying with flexible solve.

【解决方案1】：

conda-forge 的 metview 包仅适用于 osx-64 和 linux-64。看起来你在win-64系统上。尝试使用pip install metview 安装。如果不成功，您将不得不从源代码构建。

我刚刚做了并得到了这个：

(base) C:\Users\Saeed>pip install metview

问题是它不是正确和合适的包装！它正在安装错误的版本，或者至少是不正确的！我在 jupyter 中运行它并得到了这个：

import metview as mv
