OSError:无法在Mac上找到libspatialindex_c库文件

Question

系统: Mac

我是Python的新用户，目前正在探索地理信息系统。然而，我试图用geopandas读取一个形状文件: OSError:未能找到libspatialindex_c库文件

通常使用Python3.7，但由于在这方面存在依赖关系问题，所以按照这里的建议在Python2上运行。

我在这里所做的就是使用mac终端，用python2创建新的环境，并在那里安装geopandas，并尝试读取形状文件。

conda创建-n mytest python=2.7 geopandas -c conda锻造 源激活mytest 进口地质公园 geopandas.read_file('Random_points_twitter.shp')

  id   xcoord    ycoord  data_twitt

1 1 3.29896 51.32356 1

2 2 3.29896 51.32356 2

我能在终端机上读到这篇文章。但在浏览器中，它会返回一个错误。

我所做的是首先在我的新env上安装jupyter，并在浏览器上运行一个笔记本(代码如下)

(我测试) conda安装jupyter (我的测试)jupyter-笔记本

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)，但是它给了我这个错误：

OSError:找不到libspatialindex_c库文件

当使用浏览器在木星笔记本上运行时，我的conda列表(下面)已经安装了libspatial，这给了我这个错误。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

希望它能成功。

Answer 2

在mac终端上运行brew install spatialindex解决了这一问题。
