I was trying to create a simple flask web app at /data/project/whichsub but I can't run the webservice for it.
When I try to run it using lighttpd I get the following error in the error.log file:
2016-07-12 14:00:31: (log.c.166) server started 2016-07-12 14:00:31: (mod_fastcgi.c.1103) the fastcgi-backend /data/project/whichsub/www/python/src/app.py failed to start: 2016-07-12 14:00:31: (mod_fastcgi.c.1107) child exited with status 2 /data/project/whichsub/www/python/src/app.py 2016-07-12 14:00:31: (mod_fastcgi.c.1110) If you're trying to run your app as a FastCGI backend, make sure you're using the FastCGI-enabled version. If this is PHP on Gentoo, add 'fastcgi' to the USE flags. 2016-07-12 14:00:31: (mod_fastcgi.c.1398) [ERROR]: spawning fcgi failed. 2016-07-12 14:00:31: (server.c.1021) Configuration of plugins failed. Going down. [uWSGI] getting INI configuration from /data/project/whichsub/uwsgi.ini
My .lighttpd.conf file:
fastcgi.server += ( "/whichsub" => (( "socket" => "/tmp/whichsub-fcgi.sock", "bin-path" => "/data/project/whichsub/www/python/src/app.py", "check-local" => "disable", "max-procs" => 1, )) )
And when I try using the uwsgi-plain I get the following error in uwsgi.log:

As the error indicates, my app is being run by python 3.4.0, but I need it to run with my virtual environment python which is 3.5.2.
My uwsgi.ini file:
[uwsgi] plugin = python3 socket = /data/project/whichsub/whichsub.sock chdir = /data/project/whichsub/www/python/src venv = /data/project/whichsub/www/python/venv virtualenv = /data/project/whichsub/www/python/venv module = app callable = app manage-script-name = true
My python app:
#!/data/project/whichsub/www/python/venv/bin/python # -*- coding: utf-8 -*- """Find which subtemplates contain the given text.""" from os import name as os_name from flask import Flask from flask import request from flask import render_template import pywikibot as pwb if os_name == 'posix': from flup.server.fcgi import WSGIServer app = Flask(__name__) def find_sub_templates(lookingfor: str, page: pwb.Page): found_templates =  if lookingfor in page.text: found_templates.append(template) for sub_template in page.templates(content=True): if lookingfor in sub_template.text: found_templates.append(sub_template) return found_templates @app.route('/' if os_name != 'posix' else '/whichsub/') def main(): code = request.args.get('code', 'en') family = request.args.get('family', 'wikipedia') pagetitle = request.args.get('pagetitle', '') lookingfor = request.args.get('lookingfor', '') site = pwb.Site(code, family) try: page = pwb.Page(site, pagetitle) templates = find_sub_templates(lookingfor, page) except ValueError: templates = None return render_template( 'main.html', code=code, family=family, pagetitle=pagetitle, lookingfor=lookingfor, templates=templates, ) if __name__ == '__main__': if os_name == 'posix': WSGIServer(app).run() else: app.run(debug=True)
I'm completely stuck at this point. Any help is appreciated. Feel free to ask any question.
If needed I would be happy to add you to the tool account...
