Python 如何安装菲奥娜1.6？

我正在尝试安装fiona=1.6，但出现以下错误

conda install fiona=1.6

如果我尝试安装gdal==1.11.4，我会得到以下结果

conda install -c conda-forge gdal=1.11.4

执行错误消息告诉我的操作

要搜索可能提供康达套餐的备用频道，请执行以下操作： 查找，导航到

在搜索框中键入gdal，我找到了以下安装说明：

康达安装-c康达锻造gdal=1.11.4

尝试安装gdal依赖项，也许？

Python版本 这个。您要么需要使用菲奥娜版本的更新版本1.8，要么创建一个新的EnV，其中包括那些较旧的Python版本。p> 比如说,

conda create -n fiona_1_6 fiona=1.6 python=3.5

通道默认值是必需的 您面临的另一个问题是，根据您的conda信息，您已经从配置中删除了默认通道。仅使用conda forge通道不可能安装fiona=1.6。我的建议是在配置中同时使用conda forge和默认值，但如果您需要的话，只需将conda forge设置为具有更高的优先级。你可以这样做

conda config --append channels defaults

如果您真的不想包含默认值，而只是想要一个临时解决方案，那么您可以简单地使用-channels |-c标志运行第一个命令

这仍将赋予conda forge优先权，但允许从默认值中获取缺少的依赖项

环境文件

如果您需要的不仅仅是菲奥娜，那么将一个需求文件组合起来可能更干净，比如

菲奥娜·亚马尔 然后使用以下命令创建新环境：

conda env create -f fiona_1_6.yaml

OP清楚地显示了通道中的conda forge，因此这是没有用的。为了清楚起见，这包括编辑之前的内容。@emax请将conda信息的输出添加到您的问题中，因为这在OSX上对我有效。刚刚添加。问题是，在我安装osmnx包之前，一切都正常工作。似乎与libgdal有一个共同点version@emax谢谢现在我可以看到您的潜在问题，并相应地更新了答案。为什么您的频道中删除了默认设置？康达福吉并不是一个自给自足的渠道。

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

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

conda env create -f fiona_1_6.yaml
