त्रुटि: [एर्र्नो 98] पता पहले से ही उपयोग में है

Question

मैं एक साधारण फ्लास्कैप बना रहा हूं जिसे मैं हरोकू पर तैनात करने जा रहा हूं, पहली बार उसकेोकू पर एक पायथन ऐप तैनात कर रहा था, जिसमें कहा गया था कि मैं बंदूक के लिए नया हूं।

अतिरिक्त नोट्स: वर्चुअल वातावरण का उपयोग करना।

कुप्पी बोतल == 0.10.1

gunicorn == 19.3.0

'अजगर run.py' काम करता है

का उपयोग करते हुए 'फोरमैन स्टार्ट' मैं का उपयोग करने के संस्करण निम्नलिखित त्रुटि

जो मैंने पढ़ा है, वह बंदरगाह से कई धागे के निर्माण की अनुमति देता है, जो मुझे लगता है कि धागे उसी पोर्ट तक पहुंचने की कोशिश कर रहे हैं जो पहले से ही त्रुटि में उपयोग करता है। हालांकि मुझे नहीं पता कि इसे कैसे हल किया जाए, किसी भी मदद की सराहना की जाती है।

Answer 1

ऐसा लगता है कि आप रनिंग कर रहे हैं: ऐप के बजाय flaskapp: flaskapp और run.py एक और उदाहरण खोलने का प्रयास कर रहा है।

16:35:44 web.1 | File "/home/adminuser/Desktop/Github/SoftwareEng/barcodeServer/SoftwareEng/run.py", line 3, in <module> 

सबसे पहले, हमेशा रन संपुटित:

if __name__ == '__main__': 
    flaskapp.run(debug=True) 

और अपने procfile कॉल करने के लिए अद्यतन app.__init__.py बजाय:

web: gunicorn app:flaskapp --log-file=- 

पुनश्च: मैं नहीं जानता कि क्या procfile या फोरमैन हैं - Heroku चीजें?
