系统:Mac OSX
我是 Python 的新用户,目前正在探索 GIS。尝试使用 geopandas 读取形状文件,但我得到:OSError:找不到 libspatialindex_c 库文件
正常使用 Python 3.7,但由于 geopandas 在这方面存在依赖性问题,因此按照此处的建议在 Python2 上运行。
我在这里所做的是使用mac终端,使用python2创建新环境并在那里安装geopandas并尝试读取形状文件。
conda create -n mytest python=2.7 geopandas -c conda-forge
源激活 mytest
导入地理熊猫
geopandas.read_file('Random_points_twitter.shp')
id xcoord ycoord data_twitt
0 0 5.27735 50.25398 0
1 1 3.29896 51.32356 1
2 2 3.29896 51.32356 2
我可以在终端中成功阅读此内容。但是在浏览器中,它返回一个错误。
我所做的是首先在我的新环境上安装 jupyter 并在浏览器上运行笔记本(代码如下)
(mytest) conda install jupyter
(mytest) jupyter-notebook
在带有新笔记本的浏览器上,尝试导入和读取形状文件(类似于我在终端中所做的),但它给了我这个错误:

我的 conda 列表(如下)已经安装了 libspatial,但是当使用浏览器在 Jupyter Notebook 上运行时给我这个错误。有任何想法吗?
