Plone 4 buildout, setuptools and zc.buildout

1

This is driving me nuts, sorry :slightly_smiling:

I try to run my buildout for the latest Plone 4:

cat requirements.txt

setuptools==5.8
zc.buildout==2.2.5

cat buildout.cfg

[buildout]
socket-timeout = 3

extends = http://dist.plone.org/release/4.3-latest/versions.cfg
find-links = http://dist.repoze.org/

show-picked-versions = true

parts =
    instance

[instance]
recipe = plone.recipe.zope2instance
eggs =
    Plone
    Pillow

user = admin:admin
http-address = 8080
shared-blob = on

environment-vars =
    PTS_LANGUAGES=en

Resulting in:

An internal error occurred due to a bug in either zc.buildout or in a
recipe being used:
Traceback (most recent call last):

If I try it without pins for setuptools and zc.buildout I am getting lots of version conflicts for setuptools and zc.buildout

Did someone has any pointers ?

Thanks !

I've been using zc.buildout 2.4.0 and setuptools 18.5. Newer versions of each would probably also work, but I know that I usually don't have problems with these.

Thanks, now I get something else :slightly_smiling:

cat requirements.txt:

setuptools==18.5
zc.buildout==2.4.0

pip install -r requirements.txt
./bin/buildout -vvv

Works here. without any `requirements.txt'

tested the same with ./bin/pip install -U zc.buildout and works too.

Hm, interesting, it is here still not working, even in a new dir I get errors:

Installing 'plone.recipe.zope2instance'.
We have no distributions for plone.recipe.zope2instance that satisfies 'plone.recipe.zope2instance==4.2.18'.
Could't load zc.buildout entry point default
from plone.recipe.zope2instance:
'tuple' object has no attribute 'is_prerelease'.

I will try later something else :slightly_smiling:

Thanks, at least I know now, that it is not my buildout

I usually do this to debug buyildout problems:
./bin/python -m pdb ./bin/buildout

Now you are in a pdb and you cat set breakpoints and debug who what is happening there.

Anyway I usually pip install the latest zc.buildout (2.5.0, which has way better version conflict reporting) and the latest setuptools.
I still did not try the latest one (20.2.2) but other 20.x version were working fine.

To be sure I tested that on another location:
Different machine, different data center, different OS, same error:

 Installing.
  Getting section instance.
  Initializing section instance.
  Installing recipe plone.recipe.zope2instance.
  Getting distribution for 'plone.recipe.zope2instance==4.2.18'.
...
...
AttributeError: 'tuple' object has no attribute 'is_prerelease'

Not sure anymore, guess I will try the UI-Installer next :slightly_smiling:

@alert thanks for the tip !

Same error on Fedora 23, following @jensens approach step by step

Fixed !

Reason was the order of stuff in buildout.cfg, I changed it to:

[buildout]
extensions = buildout.threatlevel
extends = http://dist.plone.org/release/4-latest/versions.cfg
versions = versions

parts = instance

[instance]
recipe = plone.recipe.zope2instance
user = admin:admin
http-address = 8080
shared-blob = on
eggs =
        Plone
        Pillow

and now it is working

You can also run buildout -D
for debugging :slight_smile:
