Scrapy 尝试计划作业时出错

当我尝试在部署项目后安排作业时，会出现以下错误：

 Traceback (most recent call last):
  File "/usr/lib/pymodules/python2.7/scrapyd/webservice.py", line 18, in render
    return JsonResource.render(self, txrequest)
  File "/usr/local/lib/python2.7/dist-packages/scrapy/utils/txweb.py", line 10, in render
    r = resource.Resource.render(self, txrequest)
  File "/usr/local/lib/python2.7/dist-packages/twisted/web/resource.py", line 250, in render
    return m(request)
  File "/usr/lib/pymodules/python2.7/scrapyd/webservice.py", line 37, in render_POST
    self.root.scheduler.schedule(project, spider, **args)
  File "/usr/lib/pymodules/python2.7/scrapyd/scheduler.py", line 16, in schedule
    q.add(spider_name, **spider_args)
  File "/usr/lib/pymodules/python2.7/scrapyd/spiderqueue.py", line 18, in add
    self.q.put(d, priority)
  File "/usr/lib/pymodules/python2.7/scrapyd/sqlite.py", line 103, in put
    self.conn.execute(q, args)
OperationalError: attempt to write a readonly database

如果在部署项目后，我去重新启动scrapyd，并在计划一个作业后，它没有问题，工作正常。但老实说，我不认为每次部署时都去重新启动scrapyd有什么意义。。。没有道理

我已经检查了DB文件夹，有一个爬网的\u project.DB文件，根目录为：root owner这可能是问题的原因
