忽略异常强制安装

sudo pip install -r requirement.txt --force      

3. python 版本升级

yum search python*
yum search python27
sudo yum install tops-python27      

4. 查看python 配置文件位置

$whereis python
python: /usr/bin/python2.6 /usr/bin/python2.6-config      

5. 查看geos及shapely依赖的GEOS版本

>>> from shapely.geos import geos_version_string, geos_version
>>> geos_version_string
'3.6.1-CAPI-1.10.1 r0'
>>> geos_version

>>> import geos
>>> geos.GEOS_VERSION
'3.6.1'      

6. 安装libspatialindex_c

Rtree and a missing libspatialindex_c library file

brew install spatialindex      

7. 安装制定版本依赖包

pip install matplotlib==1.3.1
