使用conda install geopandas安装geopandas库时会报错如下：
Solving environment: failed with initial frozen solve. Retrying with flexible solve. Solving environment: failed with repodata from current_repodata.json, will retry with next repodata source. Collecting package metadata (repodata.json): done Solving environment: failed with initial frozen solve. Retrying with flexible solve. Solving environment: Found conflicts! Looking for incompatible packages.
在已有环境中安装新的库，conda要求检查已有环境的兼容性，时间很长，而且很可能最后失败。
网上查阅解决方法发现是conda自身的问题，使用conda update --all命令也不一定能解决所有问题，没有较好的解决方法。
最后的手段：直接下一个miniconda，miniconda是基本全裸的没有包含其他包。此时xonda install geopandas 成功。
2.在vscode运行时报错oserror: could not find or load spatialindex_c-64.dll出现这个问题的原因是geopandas引用的库rtree找不到spatialindex_c-64.dll导致的，直接在python安装路径lib下寻找spatialindex_c-64.dll，然后将其复制到Miniconda3Libsite-packagesrtree文件夹下即可。
