Question

我正在使用以下链接安装软件包OSMnx：https://geoffboeing.com/2016/11/osmnx-python-street-networks/在Linux上使用 conda install -c conda-forge osmnx。
它可以工作，但是带有这样的警告：

==> WARNING: A newer version of conda exists. <==
  current version: 4.5.11
  latest version: 4.5.12

Please update conda by running

    $ conda update -n base -c defaults conda

因此，我更新了conda，然后再次在计算机中重新安装OSMnx软件包。之后，我启动Python Shell，然后输入import osmnx对其进行测试。然后出现以下错误。

Python 3.7.1 | packaged by conda-forge | (default, Nov 13 2018, 18:33:04)

搜索后，我找到了以下链接：https://github.com/darribas/contextily/issues/42但是，对我来说，要了解这是不容易的。有人可以帮我吗？

根据OSMnx documentation：“如果您对安装有任何问题，请尝试使用conda和conda-forge在新的干净虚拟环境中安装OSMnx”：

conda create --override-channels -c conda-forge -n OSMNX python=3 osmnx

这应该可以解决Fiona（依赖项）的安装/路径问题。
