Arcpy：导入arcgisscripting ImportError：DLL加载失败：找不到指定的模块-python 2.7 64位Arcgis 10.8

如何解决Arcpy：导入arcgisscripting ImportError：DLL加载失败：找不到指定的模块-python 2.7 64位Arcgis 10.8

当我尝试在64位python 2.7.16 Arcgis 10.8中导入arcpy时，出现此错误。我在.pth文件中有以下内容

C:\Program Files (x86)\ArcGIS\Desktop10.8\bin64
C:\Program Files (x86)\ArcGIS\Desktop10.8\Arcpy
C:\Program Files (x86)\ArcGIS\Desktop10.8\ArcToolBox\Scripts

在我拥有的PATH变量中

C:\Python27\ArcGISx6410.8\Lib;C:\Python27\ArcGISx6410.8\Scripts;

在PYTHONPATH中

C:\Python27\ArcGISx6410.8\python.exe;
C:\Python27\ArcGISx6410.8\DLLs;
C:\Python27\ArcGISx6410.8\lib;
C:\Python27\ArcGISx6410.8\lib\plat-win;
C:\Python27\ArcGISx6410.8\lib\lib-tk;
C:\Python27\ArcGISx6410.8;
C:\Program Files (x86)\ArcGIS\Desktop10.8\bin64;
C:\Program Files (x86)\ArcGIS\Desktop10.8\arcpy;
C:\Program Files (x86)\ArcGIS\Desktop10.8\ArcToolBox\Scripts

不确定我是否错过了任何事情。请帮忙。
