我正在通过以下链接安装包 OSMnx：https ://geoffboeing.com/2016/11/osmnx-python-street-networks/在 Linux 上使用 conda install -c conda-forge osmnx.
它有效，但有这样的警告：

==> 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

所以我更新了 conda，并在我的电脑上重新安装了 OSMnx 包。之后，我启动我的 Python shell 并进入import osmnx测试它。然后我收到以下错误。

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

经过搜索，我找到了这个链接：https ://github.com/darribas/contextily/issues/42但是我并不容易理解发生了什么。有人可以帮我吗？

根据OSMnx 文档：“如果您在安装时遇到任何问题，请尝试使用 conda 和 conda-forge 在新的、干净的虚拟环境中安装 OSMnx”：

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

这应该可以解决 Fiona（依赖项）安装/路径问题。
