系统报错：
core.js:6456 ERROR TypeError: zTree.showNodes is not a function
at TreeViewComponent.searchNode (main.js:7886)
at TreeViewComponent.change (main.js:7805)
在系统中已经引用了相关js
"scripts": [ "node_modules/jquery/dist/jquery.js",
"node_modules/ztree/js/jquery.ztree.all.js",
"node_modules/ztree/js/jquery.ztree.core.js",
"node_modules/ztree/js/jquery.ztree.exhide.js",
"node_modules/bootstrap/dist/js/bootstrap.js",
"src/assets/js/jquery-1.4.4.min.js"]
有哪位大神知道这是怎么回事吗
