如何在Heroku上使用Mechanize，BeautifulSoup，html2text

Question

I'm deploying my app to Heroku which uses mechanize, beautifulsoup4 and html2text but there are some errors regarding to the missing dependencies on heroku.

I can only manage to install BeautifulSoup by adding this line to the requirements.txt:

beautifulsoup4==4.1.3

However, I couldn't find away to install mechanize and html2text by adding to requirements.txt. I tried couple thing like: mechanize=xxx html2text=xxx (xxx = different versions) but none of them work so far.

How do I add those 2 dependencies to my requirements.txt in order to make it work on Heroku?

Thank you so much

Answer 1

I figured it out, just run pip freeze > requirements.txt and it will replace the old file by the new one with all dependencies. No need to manually add it.
