how to add new plugins?

[hadifarnoud]

in Docker deploy, I have to add plugins to requirements.txt and build the image. in regular server install, I just do pip install

how can I add plugins on heroku?

[jpvanhal]

1. Fork the repo.
2. Install pip-tools
3. Add the plugin to requirements.in.
4. Run pip-compile --output-file requirements.txt requirements.in to update the requirements.txt file.
5. Commit changes.
6. Push to Heroku.

my requirements.in file:

dj-database-url
django-bcrypt
django-secure
ndg-httpsclient  # required by requests
psycopg2
sentry
sentry-flowdock
sentry-github
sentry-sprintly
sentry-searchbutton

I couldn't reproduce that issue. Maybe your pip is too old. pip-tools requires at least v6.1.

[hadifarnoud]

was my fault. I modified it to make it Flynn ready. doing pip install setuptools --upgrade fixed it
