我正在尝试将 Django 与 Geodjango 一起使用，我遵循了所有文档步骤，但在尝试进行迁移时仍然出现此错误:
OSError: [WinError 127] : The specified procedure could not be found
models.py 是正确的，我使用的是 geodjango 站点，这是我的 settings.py

我检查并安装了 geodjango 的所有要求。
有什么建议吗？
请您参考如下方法:
您可能有多个 Python 版本，并且它们之间存在冲突。
尝试在您的 virtualenv 上安装 GDAL 并确保 gdal202.dll 在您的 virtualenv 上下文中。
还要确保您安装了来自 https://www.lfd.uci.edu/~gohlke/pythonlibs/#gdal 的正确编译版本，使用 pip 并在您的 virtualenv 中。
GDAL DLL 将位于 gdal 安装路径中。我在 settings.py 中使用这样的代码在 Windows 上设置 GeoDjango:
try:
import gdal
gdal_path = Path(gdal.__file__)
OSGEO4W = os.path.join(gdal_path.parent, 'osgeo')
os.environ["OSGEO4W_ROOT"] = OSGEO4W
os.environ["GDAL_DATA"] = os.path.join(OSGEO4W, "data", "gdal")
os.environ["PROJ_LIB"] = os.path.join(OSGEO4W, "data", "proj")
os.environ["PATH"] = OSGEO4W + ";" + os.environ["PATH"]
GEOS_LIBRARY_PATH = str(os.path.join(OSGEO4W, "geos_c.dll"))
GDAL_LIBRARY_PATH = str(os.path.join(OSGEO4W, "gdal301.dll"))
except ImportError:
GEOS_LIBRARY_PATH = None
GDAL_LIBRARY_PATH = None
