Windows上的GeoDjango :尝试在您的设置中设置GDAL_LIBRARY_PATH
Windows上的GeoDjango :尝试在您的设置中设置GDAL_LIBRARY_PATH
提问于 2017-05-24 00:23:07
我已经这样做了十几次了，但这次有些东西不起作用。
遵循文档：
https://docs.djangoproject.com/en/1.11/ref/contrib/gis/install/#windows
我正在尝试在Windows机上设置GeoDjango (这是在paperspace.com上设置的虚拟Windows10)。我的路径设置似乎有问题，但我找不出是什么问题。我已经运行了指令中突出显示的命令。我已经检查了PATH变量，一切似乎都很正常。我已经尝试将它们指向32位和64位版本的OSGeo4Win。无论如何，我每次都会得到以下输出：
C:\Python\lib\site-packages\floppyforms\__init__.py:21: UserWarning: Unable to import floppyforms.gis, geometry widgets not available

更新:我去商店买了一台新的笔记本电脑，但我仍然遇到同样的问题。这会不会是一些GeoDjango依赖项的版本问题？我不知所措，但这对我来说是一种紧急情况。

添加
GDAL_LIBRARY_PATH = r'C:\OSGeo4W64\bin\gdal202'django设置对我有效

除了之前的评论之外。您可能有一个WinError 127，找不到指定的过程。
这是因为您的系统上有多个sqlite3.dll。如果路径首先命中这两个，则gdal202会出现冲突。
您可以通过添加工作目录的更改来扩展adam starrh answers。
#Set working directory to actual working directoy of gdal
#This is required to prevent any conflicts with older SQLITE versions,
#f.e. in python path
#Prevents error in GDAL 202
#BASE_WORKINGDIRECTORY to change it back later if you need to
BASE_WORKDIRECTORY = os.getcwd()
os.chdir(os.path.dirname(lib_path))
# This loads the GDAL/OGR C library
lgdal = CDLL(lib_path)Stack Overflow用户

我也遇到了同样的错误。
django.core.exceptions.ImproperlyConfigured: Could not find the GDAL library (tried "gdal204", "gdal203", "gdal202", "gdal201", "gdal20"). Is GDAL installed? If it is, try setting GDAL_LIBRARY_PATH in your settings.首先，安装OSGeo4W，然后在您的settings.py中添加以下代码。
import os
if os.name == 'nt':
import platform
OSGEO4W = r"C:\OSGeo4W"
if '64' in platform.architecture()[0]:
OSGEO4W += "64"
assert os.path.isdir(OSGEO4W), "Directory does not exist: " + OSGEO4W
os.environ['OSGEO4W_ROOT'] = OSGEO4W
os.environ['GDAL_DATA'] = OSGEO4W + r"\share\gdal"
os.environ['PROJ_LIB'] = OSGEO4W + r"\share\proj"
os.environ['PATH'] = OSGEO4W + r"\bin;" + os.environ['PATH']如果仍然有错误，请转到C:\OSGeo4W64或C:\OSGeo4W，然后运行python manage.py check。在那里你可以找到gdalxxx.dll。请在错误消息中将文件名重命名为'gdal202‘或'gdal203’。请运行python manage.py check，这一定会起作用。
