解决方法:警告:函数作为 React 子项无效

Question

我已经更新了我的路由器，以采用第二条主要路由。

import React from 'react';
import { Router, Route, IndexRoute, browserHistory } from 'react-router';
// Containers & Pages
// Home
import HomePage from '/imports/ui/pages/home/HomePage.js';
// Accounts
import SignUp from '/imports/ui/pages/accounts/SignUp.js';
import Login from '/imports/ui/pages/accounts/Login.js';
import ForgotPassword from '/imports/ui/pages/accounts/ForgotPassword.js';
import ResetPassword from '/imports/ui/pages/accounts/ResetPassword.js';
import PaymentPage from '/imports/ui/pages/accounts/PaymentPage.js';
import CouponPaymentPage from '/imports/ui/pages/accounts/CouponPaymentPage.js';
import AccountPage from '/imports/ui/pages/accounts/AccountPage.js';
// General
import AppContainer from '/imports/ui/containers/AppContainer.js';
// In App
import DashboardContainer from '/imports/ui/containers/app/DashboardContainer.js';
import AllRecipesContainer from '/imports/ui/containers/app/AllRecipesContainer.js';
// Legal
import PrivacyPage from '/imports/ui/pages/legal/PrivacyPage.js';
import TermsPage from '/imports/ui/pages/legal/TermsPage.js';
import DisclaimersPage from '/imports/ui/pages/legal/DisclaimersPage.js';
// Admin
import AdminContainer from '/imports/ui/containers/AdminContainer.js';
import UsersAdminContainer from '/imports/ui/containers/UsersAdminContainer.js';
import RecipeStatsPage from '/imports/ui/pages/admin/RecipeStatsPage.js';
// Routes
export const renderRoutes = () => (
<Router onUpdate={() => window.scrollTo(0, 0)} history={browserHistory}>
<Route path="/" component={AppContainer}>
<IndexRoute name="Home" component={HomePage} />
<Route name="Sign Up" path="/signup" component={SignUp} />
<Route name="Log In" path="/login" component={Login} />
<Route name="Forgot Password" path="/forgotpassword" component={ForgotPassword} />
<Route name="Reset Password" path="/reset-password/:token" component={ResetPassword} />
<Route name="Coupon Payment Page" path="/coupons/:code" component={CouponPaymentPage} />
<Route name="Privacy Page" path="/privacy" component={PrivacyPage} />
<Route name="Terms" path="/terms" component={TermsPage} />
<Route name="Disclaimers" path="/disclaimers" component={DisclaimersPage} />
<Route name="Payment" path="/payment" component={PaymentPage} />
<Route name="Dashboard" path="/dashboard" component={DashboardContainer} />
<Route name="Browse All Recipes" path="/browseall" component={AllRecipesContainer} />
<Route name="Manage Account" path="/account" component={AccountPage} />
</Route>
<Route path="/manager" component={AdminContainer}>
<IndexRoute name="manager home" component={UsersAdminContainer} />
<Route path="/manager/recipes" component={RecipeStatsPage} />
</Route>
</Router>
);

当我在应用程序中导航到"/manager"时，出现错误：

警告：函数作为 React 子函数无效。如果出现以下情况，则可能会发生这种情况 您返回组件而不是从渲染返回。或者也许 你的意思是调用这个函数而不是返回它。 in Unknown(由 RouterContext 创建) 在 RouterContext 中(由 Router 创建) 在路由器中

管理容器.js

import { Meteor } from 'meteor/meteor';
import { withTracker } from 'meteor/react-meteor-data';
import Admin from '/imports/ui/layouts/Admin.js';
export default withTracker(() => {
const userHandle = Meteor.subscribe('users.myData');
const loading = !userHandle.ready();
return {
user: Meteor.user(),
loading,
};
}, Admin);

用户管理容器.js

import { Meteor } from 'meteor/meteor';
import { withTracker } from 'meteor/react-meteor-data';
import UsersAdminPage from '/imports/ui/pages/admin/UsersAdminPage.js';
export default withTracker(() => {
const usersHandle = Meteor.subscribe('users.allUsers');
const loading = !usersHandle.ready();
return {
loading,
users: Meteor.users.find().fetch(),
};
}, UsersAdminPage);

我尝试导入UsersAdminPage并将其用于索引路由的组件。我已经在 SO 上看过这个答案(函数作为 React 子级无效。如果您返回组件而不是从渲染返回，则可能会发生这种情况)。我没有看到我的错误，任何帮助将不胜感激。

您对withTracker的调用不正确。他们应该将组件传递给withTracker的结果：

export default withTracker(() => {
const userHandle = Meteor.subscribe('users.myData');
const loading = !userHandle.ready();
return {
user: Meteor.user(),
loading,
};
})(Admin);
