python - 操作系统错误: Could not find libspatialindex_c library file on Mac OSX

Question

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 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

source activate mytest

import geopandas

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

我能够在终端中成功读取此内容。但在浏览器中，它返回一个错误。

我所做的是首先在我的新环境中安装 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，尝试导入并读取形状文件(类似于我在终端中所做的操作)，但它给了我这个错误:

我的 conda 列表(如下)已经安装了 libspatial，但使用浏览器在 Jupyter Notebook 上运行时出现此错误。有什么想法吗？

Answer 1

我通过下面的代码解决了这个问题。

sudo apt-get install automake
sudo apt-get install libtool
sudo apt-get install pkg-config
curl -L https://github.com/libspatialindex/libspatialindex/archive/1.8.5.tar.gz | tar xz
cd libspatialindex-1.8.5/
./autogen.sh 
./configure
make
sudo make install
sudo ldconfig

希望它能起作用。
