解决conda安装xarray-spatial时无详细信息的UnsatisfiableError问题

问题重现

执行的安装命令：

(geo_env) C:\Users\Alex>conda install -c conda-forge xarray-spatial

错误输出：

failed

UnsatisfiableError: The following specifications were found to be incompatible with each other:

Output in format: Requested package -> Available versions
Note that strict channel priority may have removed packages required for satisfiability.

解决方法

调整通道优先级
错误提示严格的通道优先级可能过滤掉必要包，先查看当前通道设置：
```
conda config --show channels
```
若channel_priority为strict，改为flexible：
```
conda config --set channel_priority flexible
```
之后重新执行安装命令。
获取详细冲突信息
使用conda solve生成具体冲突报告，定位不兼容包：
```
conda activate geo_env
conda solve --dry-run -c conda-forge xarray-spatial
```
命令会输出包版本冲突的细节，明确问题根源。
新建干净环境安装
现有环境依赖复杂时，直接创建新环境安装：
```
conda create -n new_geo_env -c conda-forge xarray-spatial
```
安装完成后激活新环境：
```
conda activate new_geo_env
```
使用mamba替代conda
mamba是conda的高性能替代，求解速度更快、冲突信息更清晰。先在base环境安装mamba：
```
conda install -n base -c conda-forge mamba
```
再在geo_env中用mamba安装：
```
conda activate geo_env
mamba install -c conda-forge xarray-spatial
```
