@peterbe I don't get notified about emoji reactions.

This may be not needed anymore if and when jazzband/pip-tools#383 is merged

[Changaco]

I used something like sed -r 's/#.*$//' requirements.txt | xargs hashin -r requirements.txt --python-version 2.7 to work around the lack of builtin support for adding hashes to an existing requirements file.

@jezdez this is still required as the pip-tools implementation is platform specific (as it works through pip) and therefore hashes 'generated' on, for example, a Mac, cannot be used when installing dependencies on Linux.

[graingert]

@jezdez agreed, closing in favour of jazzband/pip-tools#414 (comment)

@danpalmer probably worth making a PR that uses hashin in pip-tools?
