AttributeError: 'module' has no attribute 'get_installed_distributions'

[matinde]

Context

When deploying a project with "zappa deploy [project-name]" I get the error: AttributeError: 'module' has no attribute 'get_installed_distributions'

I honestly do not know what is wrong or what I am missing. Any help please provide simple step by step instructions to solve this.

Upgrading virtualenv fixed this for me.

sudo pip install virtualenv --upgrade

Please try that and see if the problem is fixed.

[matinde]

Thanks, but I did upgrade virtualenv but it didn't work. I still get the error message.

[paulclarkaranz]

You probably have a newer pip, they made changes to their public api top level functions recently. Try downgrading with pip install pip==9.0.1 or to 8.1.2. pypa/pip#5154

[disambiguator]

I also got this to work by running sudo pip3 install virtualenv --upgrade. Thank you for your response @varunbalupuri !

[scoates]

Closing. Comment and we'll reopen if it's a Zappa problem.

AttributeError: 'pip' has no attribute 'get_installed_distributions'

For pip == 10.0.0

You can downgrade pip to >= 9.0.0 to fix this

[oxbits]

Thank you @neotheicebird! I downgraded to 9.0.3 and it fixed the issue for me:
$ pip install pip==9.0.3

[wobeng]

@scoates how come you don't consider this as a Zappa issue? adjusting to pip is better than downgrading to Zappa

[paulclarkaranz]

There are already two open issues about adapting to pip's new api (aka subprocess): #1478 #1446
Also a PR #1481, although I don't think that is the fix that the pip devs would recommend.

[shivampaw]

I'm running into this issue. I tried downgrading pip and can confirm it is done because pip --version returns 9.0.3 but i still get the same error from zappa

[disambiguator]

@shivampaw sudo pip3 install virtualenv --upgrade

[shivampaw]

nvm, turns out rebooting does fix problems...

[naamancampbell]

Installing pip==9.0.3 after activating the virtualenv works for me:

pip install virtualenv
virtualenv venv
. ./venv/bin/activate
pip install pip==9.0.3

I know this issue is closed, but this is obviously still ongoing, and I'd love if we could find a way to patch it up. Anyone clear on the mechanics of what's going wrong here? I'm happy to get my hands dirty, but only if I know what I'm doing.

[scoates]

My comment above was indeed in error, but the root of this problem is the pip changes, I believe, now.

#1478 + #1481

Hello all.

The prob is def pip. Broken in 10.x.

However, depending on your environment, you may need to downgrade pip or pip3. For my fedora box it was pip and my windows machine was pip3. Just depends which interpreter you're using for the problem file/package.

[Shaun1]

Downgrading to pip 9.0.3 (both globally and in virutualenv) worked for me too. But this sounds like a Zappa issue, not a pip issue.

[jasweet]

True. It’s that pip updated location/structure of some internal resources. Other libraries that leverage resources internal to pip can become broken when pip makes changes.

[raveenb]

I too have had this issue, downgrading pip in the virtualenv resolved this

[WonderMr]

For pip 10 use from pip._internal.utils.misc import get_installed_distributions

[MoBattah]

Breaks Zappa. None of the above suggestions worked for me.

[NathanLawrence]

@MoBattah Exact same issue, yet you couldn't get it to find the APIs even when you're running the old version? Mind posting up prints of pip -V inside and outside your virtualenvs so we can troubleshoot?

[fergyfresh]

This 100% doesn't work with pip==10.0.1 and definitely does work with pip==9.0[1|2|3]. My workaround is pip freeze-ing after installing pip9 because my base tooling is setup for 10.

[ufmayer]

Following WonderMr's post, this worked for me:

if pip.__version__ >= "10.0.0":
    from pip._internal.utils.misc import get_installed_distributions
else:
    from pip import get_installed_distributions

[nabaz]

downgrade pip and remove slim-handler if you have that option set also

[jpza]

Downgrading pip should not be a fix here since the suggested downgrade is 10 versions behind the latest

[ryanjdillon]

I just encountered this as well. According to this issue, this should be updated to use pkg_resources.working_set.

[johnyoonh]

For me it was setting the runtime properly in zappa_settings.json
