javascript - 未捕获的类型错误 : Cannot read properties of undefined (reading 'deep' ) when upgrade to vue 3. x

Question

将 vue 升级到 3.x 后，控制台显示如下错误:

Uncaught TypeError: Cannot read properties of undefined (reading 'deep')
    at withDirectives (commons1.js:10679:17)
    at Proxy.render (eval at compileToFunction (commons1.js:40198:21), <anonymous>:36:7)
    at renderComponentRoot (commons1.js:7874:44)
    at ReactiveEffect.componentUpdateFn [as fn] (commons1.js:11968:57)
    at ReactiveEffect.run (commons1.js:5819:29)
    at setupRenderEffect (commons1.js:12094:9)
    at mountComponent (commons1.js:11877:9)
    at processComponent (commons1.js:11835:17)
    at patch (commons1.js:11436:21)
    at render (commons1.js:12579:13)

我不知道发生了什么，认为这可能是一个兼容问题。我不知道如何找到哪里出了问题。我无法从输出 js 中知道哪里出了问题(从这个错误中我不知道源代码哪里出了问题)，代码如下所示:

/**
 * Adds directives to a VNode.
 */
function withDirectives(vnode, directives) {
    const internalInstance = currentRenderingInstance;
    if (internalInstance === null) {
        ( true) && warn(`withDirectives can only be used inside render functions.`);
        return vnode;
    }
    const instance = internalInstance.proxy;
    const bindings = vnode.dirs || (vnode.dirs = []);
    for (let i = 0; i < directives.length; i++) {
        let [dir, value, arg, modifiers = _vue_shared__WEBPACK_IMPORTED_MODULE_1__.EMPTY_OBJ] = directives[i];
        if ((0,_vue_shared__WEBPACK_IMPORTED_MODULE_1__.isFunction)(dir)) {
            dir = {
                mounted: dir,
                updated: dir
            };
        }
        // here throw the error message
        if (dir.deep) {
            traverse(value);
        }
        bindings.push({
            dir,
            instance,
            value,
            oldValue: void 0,
            arg,
            modifiers
        });
    }
    return vnode;
}

当遇到 dir.deep行，抛出这个错误，我应该怎么做才能解决这个问题？我试图从谷歌搜索似乎没有人面临同样的问题。

我今天遇到了这个问题，我发现问题是因为我试图使用未注册的指令。
如果您在错误发生之前的调用中放置断点，则在您的情况下at Proxy.render (eval at compileToFunction (commons1.js:40198:21), <anonymous>:36:7)你会发现类似 const _directive_focus = _resolveDirective("focus");然后你知道你缺少什么指令
