Question

我正在尝试执行以下代码：

import osmnx as ox
G = ox.graph_from_place('Manhattan Island, New York City, New York, USA', network_type='drive')
ox.plot_graph(ox.project_graph(G))

但是我得到这个错误输出：

runfile('C:/Users/username/AppData/Local/Continuum/anaconda3/pkgs/osmnx-0.8.2-py_0/site-packages/osmnx/Isochrones 1.py', wdir='C:/Users/username/AppData/Local/Continuum/anaconda3/pkgs/osmnx-0.8.2-py_0/site-packages/osmnx')

RuntimeError: b'No such file or directory'

有人可以帮我修复它吗？

这是您的pyproj安装出现的问题。如果您遵循OSMnx文档中的“如果遇到任何问题”安装说明，则应该对其进行修复（即pyproj在虚拟环境中更可靠）：https://osmnx.readthedocs.io/en/stable/#installation

此处讨论并解决了该问题：https://github.com/gboeing/osmnx/issues/203
