我的django应用程序在本地可以正常工作，但是当我部署它时，它面临着一条特定路由的uswgi seg错误。其他所有路由均正常运行。这里是视图：
def bunny(request):
"""
Filter crawler, bot and real user
:param request:
:return: serve rendered page to crawler / SPA to user
"""
......some other codes ....
path = request.get_full_path_info()
if path.startswith('/news_paper'): # <<-- seg fault for this routes only in production server
news_paper = utils(unquote(path[12:]))
if news_paper[1] == 0: # if news paper is not found return default list
return render(request, 'site_list.html')
news = News.objects.filter(news_paper=news_paper[1]).order_by('-created_at')[:15]
return render(request, 'news.html', {'news': news, 'title': news_paper[0]})
elif path == '/about/':
return render(request, 'about.html')
else:
return render(request, 'site_list.html')

DAMN ! worker 1 (pid: 4668) died :( trying respawn ...
Respawned uWSGI worker 1 (new pid: 4709)
我正在使用django和psycopg2的最新版本。
答案 0 :(得分：2)
当针对两个不同的openssl版本编译uwsgi和psycopg时，会发生此错误。 您有两种解决方案。
禁用django数据库配置的ssl
# Database
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.postgresql',
'NAME': 'mydb',
'USER': 'myuser',
'PASSWORD': 'mypassword',
'HOST': 'localhost',
'PORT': '',
'OPTIONS': {
'sslmode': 'disable'
}
}
}
要从源代码安装psyocpg2，您必须卸载上一个并尝试
pip uninstall psycopg2
pip install --no-binary :all: psycopg2
