问题：python 通过cartopy.io.shapereader读取shp文件,出现Incomplete shapefile definition in 'c:\aaa.dbf'

ditubianjie = ccrs.PlateCarree()  # 定义投影转换
fname = 'aaa.dbf'
features = shpreader.Reader(file).geometries()
# 绘制地图
ax.add_geometries(features , ditubianjie, facecolor='none', edgecolor='black', zorder=2)

解决：将shp文件(.shp，.dbf，.shx等)放在同一目录就可以了。

原因：扒拉开源代码就是这么写的,如下：

if reader.shp is None or reader.shx is None or reader.dbf is None:
   raise ValueError("Incomplete shapefile definition "
                    "in '%s'." % filename)
