我在使用Conda Forge安装软件包时遇到了麻烦，即GeoPandas和OSMNX。它一直陷于“解决环境”上。
所以我试图更新Anaconda发行版，希望能解决问题。
我尝试过conda update --all，conda update anaconda和conda update conda
每个失败都出现相同的问题：
Preparing transaction: done
Verifying transaction: failed
RemoveError: 'setuptools' is a dependency of conda and cannot be removed from
conda's operating environment.
这是完整的输出：

对于OSMnx docs，如果遇到任何问题，请尝试在虚拟环境中安装：
conda create --override-channels -c conda-forge -n OSMNX python=3 osmnx
source activate OSMNX
