Question

我正在尝试在我的Mac OS X上安装geopandas。

我做了什么：

•下载并安装了Anaconda for Python 2.7 here。图形安装程序。

•python --version会返回以下结果：Python 2.7.13 :: Anaconda 4.3.0 (x86_64)

•使用以下行安装了geopandas：conda install -c conda-forge geopandas。据我所知，此命令还安装了所有其他必需的软件包。这是安装的所有命令的列表：

click-plugins:   1.0.3-py27_0       conda-forge

shapely:         1.5.17-np111py27_2 conda-forge
xerces-c:        3.1.4-0

•运行conda list

时会显示geopandas

•我在test.py中编写了一些代码：

import geopandas as gpd

gpd.read_file("osm_mexico_city/mexico-city_mexico_roads.geojson")

问题：

•当我在终端中运行执行python test.py时，出现以下错误：

Traceback (most recent call last):
File "test.py", line 1, in <module>
import geopandas as gpd
File "//anaconda/lib/python2.7/site-packages/geopandas/__init__.py", line 4, in <module>
from geopandas.io.file import read_file
File "//anaconda/lib/python2.7/site-packages/geopandas/io/file.py", line 3, in <module>
import fiona
File "//anaconda/lib/python2.7/site-packages/fiona/__init__.py", line 69, in <module>
from fiona.collection import Collection, BytesCollection, vsi_path
File "//anaconda/lib/python2.7/site-packages/fiona/collection.py", line 9, in <module>
from fiona.ogrext import Iterator, ItemsIterator, KeysIterator
ImportError: dlopen(//anaconda/lib/python2.7/site-packages/fiona/ogrext.so, 2): Library not loaded: @rpath/libpng16.16.dylib
Referenced from: //anaconda/lib/libgdal.20.dylib
Reason: Incompatible library version: libgdal.20.dylib requires version 45.0.0 or later, but libpng16.16.dylib provides version 44.0.0

•我试过的第二种方式是通过PyCharm。我已将项目解释器设置为python 2.7。 geopandas没有出现在包列表中，因此PyCharm甚至在此之前就阻止了：

    import geopandas as gpd
ImportError: No module named geopandas

希望任何人都知道如何解决这两个问题。

安装Anaconda brew doctor后立即返回：

Please note that these warnings are just used to help the Homebrew maintainers
with debugging if you file an issue. If everything you use Homebrew for is
working fine: please don't worry and just ignore them. Thanks!

Warning: Anaconda is known to frequently break Homebrew builds, including Vim and
MacVim, due to bundling many duplicates of system and Homebrew-available
tools.

If you encounter a build failure please temporarily remove Anaconda
from your $PATH and attempt the build again prior to reporting the
failure to us. Thanks!

Warning: "config" scripts exist outside your system or Homebrew directories.
`./configure` scripts often look for *-config scripts to determine if
software packages are installed, and what additional flags to use when
compiling and linking.

Having additional scripts in your path can confuse software installed via
Homebrew if the config script overrides a system or Homebrew provided
script of the same name. We found the following "config" scripts:
  //anaconda/bin/curl-config
  //anaconda/bin/dap-config
  //anaconda/bin/freetype-config
  //anaconda/bin/gdal-config
  //anaconda/bin/geos-config
  //anaconda/bin/icu-config
  //anaconda/bin/kea-config
  //anaconda/bin/libpng-config
  //anaconda/bin/libpng16-config
  //anaconda/bin/nc-config
  //anaconda/bin/pcre-config
  //anaconda/bin/python-config
  //anaconda/bin/python2-config
  //anaconda/bin/python2.7-config
  //anaconda/bin/xml2-config
  //anaconda/bin/xslt-config

似乎与此问题有关。我如何修复这些以使我的东西工作？

我们可以忘记PyCharm问题，事实证明我有另一个python 2.7，这是他建议的那个。我已将其更改为Anaconda python 2.7，现在它提供与终端输出相同的错误。

Answer 1

面对同样的问题，最后通过这种方法解决了这个问题：

首先使用conda安装geopandas（这将安装所有依赖项）

conda install -c conda-forge geopandas
卸载Fiona

conda uninstall fiona
下载fiona wheel并安装（我从这里下载https://pypi.python.org/packages/71/ea/908bf078499b30d1ec374eb5baba016a568fc8142ee6ccf72e356d20871c/Fiona-1.7.4-cp27-cp27m-macosx_10_6_intel.whl#md5=971393c23ffc552664b7c694b992fb3e）

pip install Fiona-1.7.4-cp27-cp27m-macosx_10_6_intel.whl
重新安装geopandas

pip install git + git：//github.com/geopandas/geopandas.git

Answer 2

不确定Anaconda发生了什么，但事实证明依赖性不兼容。

conda install fiona=1.6

将Fiona降级为1.6解决了我的一切。

Geopandas安装
