我想将ReactJS导入Kivy iOS项目并在iPad上创建服务器。
但是当我跑步时,我遇到了这个错误:
Traceback (most recent call last):
File "/Users/macuser/kivy-ios/servi-ios/YourApp/main.py", line 15, in <module>
ImportError: No module named flask
2016-05-25 15:25:03.213 servi[40042:547076] Application quit abnormally!
2016-05-25 15:25:03.220 servi[40042:547076] Leaving
如果我在OS X shell上部署相同的代码(使用命令python main.py
),一切正常,但在XCode(7.3)中则没有。
如何将Flask导入Kivy项目?我的Mac上有Flask(sudo -H pip install flask
,如果有人需要的话)
我的代码(main.py
):(最后一行,错误)
import kivy
from kivy.app import App
from kivy.network.urlrequest import UrlRequest
from kivy.uix.gridlayout import GridLayout
import urllib
import flask
from flask import Flask, Response, request
app = Flask(__name__, static_url_path='', static_folder='public')
app.add_url_rule('/', 'root', lambda: app.send_static_file('index.html'))
@app.route('/api/comments', methods=['GET', 'POST'])
def comments_handler():
with open('comments.json', 'r') as f:
comments = json.loads(f.read())
if request.method == 'POST':
new_comment = request.form.to_dict()
new_comment['id'] = int(time.time() * 1000)
comments.append(new_comment)
with open('comments.json', 'w') as f:
f.write(json.dumps(comments, indent=4, separators=(',', ': ')))
return Response(
json.dumps(comments),
mimetype='application/json',
headers={
'Cache-Control': 'no-cache',
'Access-Control-Allow-Origin': '*'
}
)
if __name__ == '__main__':
app.run(port=int(os.environ.get("PORT", 3000)))

使用React Native可以编写Native Android / IOS应用程序。但是,您可以使用React Native,Redux和Flask Rest API在本地Android设备和远程服务器之间交换数据。
