本文介绍了如何在Python3环境下安装FileGDB驱动，包括安装GDAL库、拷贝FileGDBAPI.dll到指定目录，并修改osgeo/__init__.py文件以使FileGDB驱动生效。同时，针对pyinstaller打包后识别问题，提供了设置GDAL配置选项的方法，确保打包应用能正确识别FileGDB和中文路径。

python3安装FileGDB读写驱动
环境
系统：win10x64
python：3.6.5x64
安装步骤
安装gdal： GDAL‑2.4.1‑cp36‑cp36m‑win_amd64.whl

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

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

测试，已成功加载FileGDB：

C:\WINDOWS\system32>ogrinfo --formats
Supported Formats:
  FileGDB -vector- (rw+): ESRI FileGDB
  PCIDSK -raster,vector- (rw+v): PCIDSK Database File
  netCDF -raster,vector- (rw+s): Network Common Data Format
  JP2OpenJPEG -raster,vector- (rwv): JPEG-2000 driver based on OpenJPEG library
  ...

ipython测试，可以看到gdb_driver为空，目前为止还是不能使用

修改osgeo/__init__.py文件：注释15行，取消注释17行

# __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

再次测试，成功！

测试代码

# -*- coding: utf-8 -*-

import osgeo
from osgeo import ogr, osr, gdal
import sys


gdb_driver = ogr.GetDriverByName("FileGDB")
print(gdb_driver)
gdb_driver = ogr.GetDriverByName("ESRI Shapefile")
print(gdb_driver)
gdb_driver = ogr.GetDriverByName("Geojson")
print(gdb_driver)

添加头后：

from osgeo import ogr, osr, gdal

# 激活filegdb,打包后识别filegdb中文数据目录不识别、pycharm中识别filegdb和中文数据目录

gdb_driver = ogr.GetDriverByName("FileGDB")

pyinstaller 打包

不加-F:
    # 激活filegdb,打包后识别filegdb但中文数据目录不识别、pycharm中识别filegdb和中文数据目录
    gdal.SetConfigOption("GDAL_FILENAME_IS_UTF8", "NO")
    gdal.AllRegister()
    # 激活中文路径,打包后识别中文数据目录、pycharm中识别中文数据目录
    gdal.SetConfigOption("GDAL_FILENAME_IS_UTF8", "YES")

    pyinstaller   testgdb.py   ---拷贝osgeo中的东西到osgeo
    pyinstaller  --add-data='osgeo;osgeo' testgdb.py
加-F:
    pyinstaller -F  testgdb.py   ---找不到osgeo
    pyinstaller -F --add-data='osgeo;osgeo' testgdb.py  识别filegdb和中文
