Python中安装GDAL

• 1. 安装步骤
• 2. 测试
• 3. 参考

1. 安装步骤

步骤1，终端/命令行中输入：

pip install gdal

如果出现错误：

Traceback (most recent call last):
    File "/tmp/pip-install-h_n_kokk/gdal_0c5c253514974d76a20d2183c5b4798d/setup.py", line 188, in get_gdal_config
      return fetch_config(option, gdal_config=self.gdal_config)
    File "/tmp/pip-install-h_n_kokk/gdal_0c5c253514974d76a20d2183c5b4798d/setup.py", line 90, in fetch_config
      raise gdal_config_error(e)
  __main__.gdal_config_error: [Errno 2] No such file or directory: 'gdal-config': 'gdal-config'
  
  During handling of the above exception, another exception occurred:

步骤2，安装 libgdal-dev：

 sudo apt install libgdal-dev

重复步骤1，如果出现错误：

       SWIG_Python_SetConstant(d, "GVOT_MIN_TARGET_HEIGHT_FROM_DEM",SWIG_From_int(static_cast< int >(GVOT_MIN_TARGET_HEIGHT_FROM_DEM)));

步骤3，安装gdal的依赖库:

sudo apt-get install gdal-bin libgdal-dev python3-gdal

然后，重复步骤1，应该就好了。

2. 测试

测试：

from __future__ import print_function
from osgeo import gdal
print("GDAL's version is:" + gdal.__version__)
print(gdal)

输出：

GDAL's version is:2.2.3
<module 'osgeo.gdal' from '/usr/lib/python3/dist-packages/osgeo/gdal.py'>
