hi all, What is the minimum Version of pip required to install 2.13.27? cu, brunni On Mon, Jan 29, 2018 at 10:31:14AM +0100, Michael Brunnbauer wrote:

hi

I used to install with

./bin/easy_install --index-url=http://download.zope.org/Zope2/index/2.13.xx/ Zope2

but I remember a conversation here that this is deprecated and support will be dropped at any time. No idea wether that time has arrived but the 2.13.27 directory is not populated yet.

So the correct method to install with virtualenv is the one described here?

https://zope.readthedocs.io/en/2.13/INSTALL-virtualenv.html

./bin/pip install \ --no-binary zc.recipe.egg \ -r https://zopefoundation.github.io/Zope/releases/2.13.27/requirements.txt

pip says "no such option: --no-binary" but I am still using distribute-0.6.45 and virtualenv-1.9.1 (the virtualenv pip seems to be 1.3.1 shipped with virtualenv). I have many options now and not a clue which one will work and what would break then:

-Update virtualenv -Update distribute and virtualenv -Install pip -Switch to setuptools (probably the recommended way which would break most things? :-))

Hello Michael, On Wed, Jan 31, 2018 at 09:39:53AM +0100, Michael Howitz wrote:

These versions are really old. You could try to omit `--no-binary zc.recipe.egg` from the command line shown above and see if this is successful. (`--no-binary zc.recipe.egg` is needed because otherwise modern pip versions think that zc.recipe.egg is an egg and not the name of a package. I don???t know what older pip versions without support for wheels do in this case.)

Works for a while but then at some point setuptools_scm cannot be installed automatically. If I download and install it manually in the virtualenv subdir before starting pip, the install for Zope2 seems to finish. Same problem later with "./bin/pip install Products.ZSQLMethods": No local packages or download links found for pytest-runner

This would be the first step I???d suggest: update the used virtualenv package and create a new virtualenv to install Zope there.

virtualenv was installed with easy_install and easy_install says "Best match: virtualenv 1.9.1", which is the current version. So what would be the best way to update virtualenv?

Distribute is dead nowadays all its changes have been merged back into setuptools. It is no longer needed/suggested to use distribute.

Yeah I get that.

...

-Switch to setuptools (probably the recommended way which would break most things? :-))

I don???t understand what you want to switch to setuptools.

My system. Because setuptools is not installed. If I install it while other stuff was installed with Distribute, what is the probability that anything inside or outside my virtual environments will break? That's the question I'm asking myself. cu, brunni -- ++ Michael Brunnbauer ++ netEstate GmbH ++ Geisenhausener Straße 11a ++ 81379 München ++ Tel +49 89 32 19 77 80 ++ Fax +49 89 32 19 77 89 ++ E-Mail brunni@netestate.de ++ http://www.netestate.de/ ++ ++ Sitz: München, HRB Nr.142452 (Handelsregister B München) ++ USt-IdNr.

Hello Michael,

I installed virtualenv 15.1.0 manually and tried again with the --no-binary option. Works fine - no need to install setuptools_scm manually.

Nice, so keep using the current virtualenv version.

But total loss of control and understanding occurs again when I try to install Products.ZSQLMethods with "./bin/pip install Products.ZSQLMethods":

... Found existing installation: Zope2 2.13.27 Uninstalling Zope2-2.13.27: Successfully uninstalled Zope2-2.13.27 Successfully installed AccessControl-4.0b3 AuthEncoding-4.0.0 BTrees-4.4.1 Chameleon-3.2 ExtensionClass-4.3.0 Persistence-3.0b2 Products.ZSQLMethods-3.0.1 Record-3.4 RestrictedPython-4.0b2 ZODB-5.3.0 Zope-4.0b3 Zope2-4.0b1 ipaddress-1.0.19 persistent-4.2.4.2 waitress-1.1.0 z3c.pt-3.1.0 zodbpickle-0.7.0 zope.browserpage-4.2.0 zope.browserresource-4.2.1 zope.globalrequest-1.4 zope.pagetemplate-4.3.0

This cannot be intended - can it? Did I make a mistake?

The latest release of Products.ZSQLMethods is no longer compatible with Zope2, so you have to force pip to install an older version. According to https://pypi.org/project/Products.ZSQLMethods/ the last version which is compatible with Zope2 is 2.13.5, so you should install it using: ./bin/pip install Products.ZSQLMethods==2.13.5 (You should create a new virtualenv as this call of pip install does not undo the changes pip did while you were installing the latest version.) If you want to install other packages, you should look up the latest Zope2 compatible version on PyPI. But there might be some extra versions which do not show up in the change log. So also take a look at „Release History“ on the left side below „Navigation“. (This feature only exists on the new PyPI not on pypi.python.org.) -- Mit freundlichen Grüßen Michael Howitz

Hi Jesus, thank you for trying out Zope 2.13.27. Am 01.02.2018 um 21:19 schrieb Jesus Cea <jcea@jcea.es>:

After installing Zope 2.13.27, I see this:

I installed creating a virtualenv and then, inside:

$ bin/pip install Zope2==2.13.27

The suggested way to install Zope 2 is: $ bin/pip install --no-binary zc.recipe.egg -r https://zopefoundation.github.io/Zope/releases/2.13.27/requirements.txt Does the exception also happen if you install Zope 2.13.27 this way? (in a new virtualenv) (Without the requirements file some too new versions of deepened packages are getting installed.) I get another error if I install Zope2 as you did. What did you do after installing the packages? What command did you call to get the traceback? See http://zope.readthedocs.io/en/2.13/INSTALL-virtualenv.html for details.

$ bin/pip install "Products.ZSQLMethods<3.0“

I think this one is correct.

I have reverted to Zope 2.13.26 for now :-(.

Hi Jesus, Am 06.02.2018 um 21:02 schrieb Jesus Cea <jcea@jcea.es>: […]

it works. Nice. Upgraded! :-).

Nice!

Sorry for wasting your time.

It seemed that actually I was wasting your time by writing a too short announcement. Sorry for that.

The announcement email is quite short, 3 paragraphs. One of them is just this:

""" You can download it via PyPI: https://pypi.org/project/Zope2/2.13.27 """

Yes, I can download it, but I can not install it via PYPI as a regular package. It doesn't work. In fact <https://pypi.org/project/Zope2/2.13.27> shows "pip install Zope2==2.13.27", that we have seen as wrong command to install.

You are right.

I wonder why "requirements.txt" in pypi package doesn't pin dependencies versions, as listed. Is that a PIP bug?.

It does not seem be supported by pip, at least I did not find a way to trick it to install the requirements.txt from inside a package it should install. Anyone else who has a tip?

The thing is:

1. Zope2 can not be installed as 99.9% other packages, just doing "pip install".

2. The announcement email points to a webpage showing a PROMINENT install command that produce a non-working configuration.

You are right, I am looking forward to create a more helpful announcement next time.

A simple possibility is just to add paragraph in future announcement emails just saying: "This package ca not be installed in the regular way. Follow instructions in http://....“.

Thank you for your valuable feedback. -- Mit freundlichen Grüßen Michael Howitz
