我想用spatialite 创建一个矢量GPKG。

在文档的帮助下（此处：http ://www.gaia-gis.it/gaia-sins/spatialite-sql-4.3.0.html#p16gpkg ），我创建了一个sql如下所示的脚本：

SELECT EnableGpkgMode();
SELECT gpkgCreateBaseTables();

CREATE TABLE grid ('fid' INTEGER NOT NULL PRIMARY KEY AUTOINCREMENT);
SELECT gpkgAddGeometryColumn('grid', 'geom', 'GEOMETRY', 0, 0, 4326);

这是我的输出：

$ rm -f test.gpkg && spatialite test.gpkg < test.sql

Error: near line 5: FOREIGN KEY constraint failed

我做错了什么 ？
