Description:

I'm trying to bootstrap "pip setuptools wheel" with require hashes without using a hack.

What I've run:

tee requirements.txt <<HEREDOC
pip==8.1.2 \\
    --hash=sha256:6464dd9809fb34fc8df2bf49553bb11dac4c13d2ffa7a4f8038ad86a4ccb92a1 \\

python get-pip.py --require-hashes --no-wheel --no-setuptools -rrequirements.txt --src

This is a massive hack, because I'm using --src to 'comment' out the extra "pip" to avoid the dreaded DoubleRequirement error , getting get-pip.py to run,

pip.main(['install', '--upgrade', '--require-hashes', '--no-wheel', '--no-setuptools', '-rrequirements.txt', '--src', 'pip'])

Because "--src" is noop when there's no "-e"

Thanks for filing this issue! It seems like no one got to actually responding to this issue before.

Is this still an issue? I'm not sure I understand what you're trying to do here -- is it that you're trying to install pip, setuptools and wheel while validating their hashes, using pip? What scenario is giving you the DoubleRequirementError?

Aside, using pip.main was never a supported way of using pip and in pip 10, that usage will now be broken.

Thanks and sorry for the wait.

[graingert]

I'm trying to install pip setuptools and wheel and validate their hashes. I can use --src to get pip to only see one pip

[pradyunsg]

Could you report this over at pypa/get-pip.py?

It's really an issue related to that.

[jdtriska]

@graingert Did you ever come up with a solution for this? I'm running into the same issue.

[graingert]

@jdtriska nope, and I've not got around to reporting it to the right project, could you do it for me?

[gutsytechster]

Since the issue belongs to another project, it can be closed IMO. :)

[uranusjr]

Or we can let someone with the permission to transfer the issue there (I don’t).

[pradyunsg]

Just double checked: this is still an issue with the new resolver.

[graingert]

This is no longer an issue for me as I've decommissioned all the platforms that didn't have a new enough pip to support --require-hashes

[graingert]

Also for people still using such platforms I'd recommend using the virtualenv.pyz bootstrap: https://virtualenv.pypa.io/en/latest/installation.html#via-zipapp

Thanks. This article went useful for me on a local project.

^^^ Spam? 😕

[stdedos]

And also - Is there a "script" to generate me requirements.txt that I need, in order to do

python get-pip.py --prefix=/usr/local/ --require-hashes -rrequirements.txt --src

replicatably in the future?

(idk if I care about --no-wheel --no-setuptools, and whether it affects what I'm asking for)
