Saya menggunakan aplikasi Flask saya mengikut panduan Cara Melayan Aplikasi Flask dengan uWSGI dan Nginx pada Ubuntu 14.04 Ia boleh digunakan dengan jayanya menggunakan contoh mudah dalam tutorial, tetapi ia tidak berfungsi apabila menggantikan fail kemasukan aplikasi dengan saya. sendiri, dan Perkara yang peliknya ialah ia digunakan secara langsung dalam persekitaran virtualenv

python wsgi.py

boleh, tetapi gunakan

uwsgi --socket 0.0.0.0:5000 --protocol=http -w wsgi

tidak berfungsi, ralatnya adalah seperti berikut:
