pyvirtualdisplay + nginx + flask + uwsgi doesn't find Xvfb in PATH although it works fine without uwsgi. also code works fine without pyvirtualdisplay

here is the code 

display = Display(visible=False,size=(int(width), int(height)))  
display.start()

capability = webdriver.DesiredCapabilities.FIREFOX
capability['handleAlerts'] = True
capability['acceptSslCerts'] = True
capability['acceptInsecureCerts'] = True
capability['javascriptEnabled'] = True
capability['marionette'] = True

capability['locationContextEnabled'] = False
capability['applicationCacheEnabled'] = False
capability['browserConnectionEnabled'] = False
capability['databaseEnabled'] = False

profile = FirefoxProfile()
#profile.set_preference("browser.privatebrowsing.autostart", True)
profile.set_preference("general.useragent.override",useragent)
profile.set_preference("network.proxy.socks_port",PORT)
profile.set_preference("network.proxy.socks",PROXY)
profile.set_preference("network.proxy.type",1)
profile.set_preference("network.proxy.http",PROXY)
profile.set_preference("network.proxy.http_port",PORT)
profile.set_preference("network.proxy.ssl_port",PORT)
profile.set_preference("network.proxy.ssl",PROXY)

profile.set_preference("intl.accept_languages", "en-GB, en")
profile.set_preference("browser.search.countryCode", "GB")

profile.set_preference("geo.enabled", False)

ops = Options()  
ops.log.level="error"
binary = FirefoxBinary(firefox_path = 'firefoxpath')
driver = webdriver.Firefox(firefox_binary=binary, firefox_options = ops,executable_path='/usr/local/bin/geckodriver', capabilities = capability, firefox_profile = profile)

This seems to be a PATH problem. Print your PATH before calling Display:

import os
print(os.environ['PATH'])
display = Display(visible=False,size=(int(width), int(height)))  
display.start()
