我的根 Firebase 配置代码位于名为 FirebaseConfig.js 的文件中。我希望能够从整个应用程序的容器组件访问在那里配置的数据，以便配置特定于所述子组件的子引用。

FirebaseConfig.js

import React, { Component } from 'react';
import * as firebase from 'firebase';

class FirebaseConfig extends Component {
  render() {  
    const config = {...
    };
  firebase.initializeApp(config);
  // INIT DB REFERENCE
  const db = firebase.database();
  const dbRef = db.ref();
  // INIT STORAGE REFERENCE
  const storage = firebase.storage();
  const storageRef = storage.ref();
  console.log("FB INIT'D with STORAGE REF: " + storageRef);

  return FirebaseConfig; 
    }
  }
 export default FirebaseConfig;

文件结构

src
 |__App.js
 |__index.js
 |__FirebaseConfig.js
 |__ /Home
     |__ Home.js …

使用XCode 7.1,OS X 10.10.5

我正在实现ENSideMenu库,并且我在库中使用两个方法遇到此错误:

    if (NSClassFromString("UIVisualEffectView") != nil) {
        // Add blur view
        var visualEffectView = UIVisualEffectView(effect: UIBlurEffect(style: .Light)) as UIVisualEffectView
        visualEffectView.frame = sideMenuContainerView.bounds
        visualEffectView.autoresizingMask = .FlexibleHeight | .FlexibleWidth // error points to .FlexibleHeight
        sideMenuContainerView.addSubview(visualEffectView)
    }
    else {
        // TODO: add blur for ios 7
    }
}

public convenience init(sourceView: UIView, menuViewController: UIViewController, menuPosition: ENSideMenuPosition) {
    self.init(sourceView: sourceView, menuPosition: menuPosition)
    self.menuViewController = menuViewController
    self.menuViewController.view.frame = sideMenuContainerView.bounds
    self.menuViewController.view.autoresizingMask = .FlexibleHeight | .FlexibleWidth // error points to .FlexibleHeight
    sideMenuContainerView.addSubview(self.menuViewController.view)
}

两者都指向 …

我正试图把烧瓶挂到mongoengine上.所有模块似乎都已成功安装.这是我的导入,而ln 4是错误源自的地方:

import os
from flask import Flask, render_template, send_from_directory
from mongoengine import connect
from flask.ext.mongoengine import MongoEngine

这是我得到的错误:

File "app.py", line 4, in <module>
from flask.ext.mongoengine import MongoEngine
File "/Users/name/Desktop/venv3/lib/python2.7/site-packages/flask/exthook.py" line 87, in load_module
raise ImportError('No module named %s' % fullname)
ImportError: No module named flask.ext.mongoengine

我可能做错了什么或者如何获得flask.ext.mongoengine的任何想法？

我在单独的文件夹中有两个reducer,用于与此类似的结构中的单独组件:

index.js
       /componentOne
           |_ componentOne.js
           |_ componentOneActionCreator.js
           |_ componentOneReducer.js
       /componentTwo
           |_ componentTwo.js
           |_ componentTwoActionCreator.js
           |_ componentTwoReducer.js

这些Reducers中的每一个都在应用程序中单独工作 - 当我createStore进入index.js(他们import进入)时 - 但如果我尝试使用它们combineReducers(),它们的功能都不起作用(但不会打破UI).我认为这与州有关 - 更多代码供以下参考:

index.js

const rootReducer = combineReducers({
  componentOneReducer,
  componentTwoReducer
});

let store = createStore(rootReducer, applyMiddleware(thunk))

componentOneReducer

export default(state = {}, payload) => {

  let newState = JSON.parse(JSON.stringify(state));

  switch (payload.type) {
    case 'REQUEST_DATA':
        newState.isLoading = true;
        return newState;
    case 'RECEIVE_DATA':
        newState.isLoading = false;
        newState.pageData = payload.payload;
        newState.pageName = payload.payload.pageName;

        return newState
    default: …

我有以下路线:

<Switch>
  <Route path='/:profileType/:profileId' component={Profile}/>
  <Route path='/about/:aboutThing' component={AboutThing}/>
</Switch>

当我尝试去/about/:aboutThing- 它被认为是一条{Profile}路线.这是有道理的,因为技术上:profileType可以是任何字符串,因此任何嵌套路由都将被识别为Profile.

我想知道是否可以在{AboutThing}不改变路线的情况下进行渲染.从技术上讲,/about应该是该路线的保留字.我试过做:

<Route exact path='/about/:aboutThing' component={AboutThing}/>

但这也不起作用.尝试不必在该路径中添加额外的字符串以使其工作.有什么想法/想法吗？
