我正在尝试安装fiona=1.6，但出现以下错误

conda install fiona=1.6
WARNING: The conda.compat module is deprecated and will be removed in a future release.

如果我尝试安装gdal==1.11.4，我会得到以下信息

conda install -c conda-forge gdal=1.11.4

Python 版本

Conda Forge 频道只有用于 Python 2.7、3.4 和 3.5 的 gdal v1.11.4 。您要么需要使用较新版本的 Fiona（当前为 1.8），要么需要创建一个包含这些较旧 Python 版本之一的新环境。

例如，

conda create -n fiona_1_6 fiona=1.6 python=3.5

频道defaults是必需的

您面临的另一个问题是您已从defaults配置中删除了通道（根据您的conda info）。fiona=1.6仅使用conda-forge通道是不可能安装的。我的建议是在你的配置中同时拥有conda-forge和defaults，但只是设置conda-forge为具有更高的优先级（如果这是你想要的）。你可以这样做，

conda config --append channels defaults

如果您真的不想包含defaults，而只是想要一个临时解决方法，那么您可以简单地运行带有--channels | -c标志的第一个命令

conda create -n fiona_1_6 -c conda-forge -c defaults fiona=1.6 python=3.5

这仍将给予conda-forge优先权，但允许缺少的依赖项来自defaults.

环境文件

如果您需要的不仅仅是 Fiona，那么将需求文件放在一起可能会更干净，就像这样

fiona_1_6.yaml

name: fiona_1_6
channels:
 - conda-forge
 - defaults
dependencies:
 - python=3.5
 - fiona=1.6
 - osmnx

然后用这个创建新环境：

conda env create -f fiona_1_6.yaml

执行错误消息告诉我的操作，

要搜索可能提供您正在寻找的 conda 包的替代渠道，请导航至https://anaconda.org

并gdal在搜索框中输入将我带到https://anaconda.org/conda-forge/gdal，其中包含以下安装说明：

conda install -c conda-forge gdal=1.11.4

尝试安装gdal依赖项，也许？
