标签: python django python-3.x geodjango

我尝试将DjangoGeodjango一起使用,我遵循了所有文档步骤,但是在尝试进行迁移时仍然遇到此错误:

OSError: [WinError 127] : The specified procedure could not be found

models.py是正确的,我正在geodjango网站上使用,这是我的settings.py

我已检查并安装了geodjango的所有查询。

有什么建议吗?

答案 0 :(得分:0)

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。

还要确保使用pip在virtualenv内从https://www.lfd.uci.edu/~gohlke/pythonlibs/#gdal安装了正确的编译版本。
