python3安装FileGDB读写驱动

python3安装FileGDB读写驱动

环境

• 系统：win10x64
• python：3.6.5x64

安装步骤

1. 安装gdal： GDAL‑2.4.1‑cp36‑cp36m‑win_amd64.whl

   pip install GDAL-2.4.1-cp36-cp36m-win_amd64.whl
   

2. 安装FileGDBAPI.dll：下载地址

   拷贝FileGDBAPI.dll至C:\Program Files\Python36\Lib\site-packages\osgeo目录，安装目录与python安装目录一致

   注意： GDAL 3.x 版本还需要把gdalplugins\disabled中的ogr_FileGDB.dll移动到gdalplugins目录

3. 测试，已成功加载FileGDB：

   C:\WINDOWS\system32>ogrinfo --formats|findstr "GDB"
     FileGDB -vector- (rw+): ESRI FileGDB
     OpenFileGDB -vector- (rov): ESRI FileGDB
   

4. ipython测试，可以看到gdb_driver为空，目前为止还是不能使用（GDAL 3.x 版本不需要此步骤）

   >ipython

   In [1]: from osgeo import ogr
   
   In [2]: gdb_driver=ogr.GetDriverByName("FileGDB")
   
   In [3]: gdb_driver
   
   In [4]:
   

5. 修改osgeo/__init__.py文件：注释15行，取消注释17行（GDAL 3.x 版本不需要此步骤）

   # __init__ for osgeo package.
   
   # unofficial Windows binaries: set GDAL environment variables if necessary
   import os
   
   try:
       _here = os.path.dirname(__file__)
       if _here not in os.environ['PATH']:
           os.environ['PATH'] = _here + ';' + os.environ['PATH']
       if 'GDAL_DATA' not in os.environ:
           os.environ['GDAL_DATA'] = os.path.join(_here, 'data', 'gdal')
       if 'PROJ_LIB' not in os.environ:
           os.environ['PROJ_LIB'] = os.path.join(_here, 'data', 'proj')
       if 'GDAL_DRIVER_PATH' not in os.environ:
           #pass
           # uncomment the next line to enable plugins
           os.environ['GDAL_DRIVER_PATH'] = os.path.join(_here, 'gdalplugins')
   except Exception:
       pass
   
   del os
   

6. 再次测试，成功！
