You can also add it to upcoming builds of an existing application:

$ heroku config:add BUILDPACK_URL=https://github.com/aneesh-neelam/heroku-buildpack-python-talib.git

The buildpack will detect your app as Python if it has the file requirements.txt in the root.

It will use Pip to install your dependencies, vendoring a copy of the Python runtime into your slug.

TA-Lib prebuilt libraries and the Python wrapper will be installed if the file requirements.txt has TA-Lib as a dependency. The prebuilt libraries are hosted here

Specify a Runtime

You can also provide arbitrary releases Python with a runtime.txt file.

$ cat runtime.txt
python-3.4.2

Runtime options include:

  • python-2.7.8
  • python-3.4.2
  • pypy-2.4.0 (unsupported, experimental)
  • pypy3-2.4.0 (unsupported, experimental)

Other unsupported runtimes are available as well.
