用zappa部署django不起作用

Question

我試着用zappa多次部署django， 得到以下錯誤。

{ 
    "message": "An uncaught exception happened while servicing this request. You can investigate this with the `zappa tail` command.", 
    "traceback": [ 
     "Traceback (most recent call last):\n", 
     " File \"/var/task/handler.py\", line 441, in handler\n response = Response.from_app(self.wsgi_app, environ)\n", 
     " File \"/tmp/pip-build-hvU2Xn/Werkzeug/werkzeug/wrappers.py\", line 865, in from_app\n", 
     " File \"/tmp/pip-build-hvU2Xn/Werkzeug/werkzeug/wrappers.py\", line 57, in _run_wsgi_app\n", 
     " File \"/tmp/pip-build-hvU2Xn/Werkzeug/werkzeug/test.py\", line 871, in run_wsgi_app\n", 
     "TypeError: 'NoneType' object is not callable\n" 
    ] 
} 

需要一些幫助，認真。

Answer 1

當我收到有關werkzeug wrapper的錯誤時，通常是因爲我的軟件包未安裝在我的虛擬環境中。

virtualenv venv 
source venv/bin/activate 
pip install Django 
pip install zappa 
# or with a requirements.txt file 
pip install -r requirements.txt 

然後運行zappa deploy命令。

Answer 2

你沒有看到真正的錯誤。按照它的說法行事：「你可以用zappa tail命令來調查」。

我想在一個窗口中運行zappa tail --since 1m，在另一個窗口中運行zappa update，您會在那裏看到真正的例外。
