代码出错，找到原因了，是路径前面要加个"r"。
import arcpy
out_path = “J:\pystudy\shili\outpath”
out_name = “fenyi0115.shp”
prjfile = “J:\pystudy\shili\fenyi.prj”
spatialref = arcpy.SpatialReference(prjfile)
Runtime error
Traceback (most recent call last):
File “”, line 1, in
File “d:\program files\arcgis\desktop10.2\arcpy\arcpy\arcobjects\mixins.py”, line 927, in init
self._arc_object.createFromFile(item)
RuntimeError: ERROR 999999: 执行函数时出错。
修改后的代码如下：prjfile = r"J:\pystudy\shili\fenyi.prj"
spatialref = arcpy.SpatialReference(prjfile)
能正常运行了。
