在Plone扩展设置中查找需求规格 [英] Find requirement specs in a Plone buildout setup

问题描述

我有一个Plone网站(大约4.2.4，从根目录中的version.txt告诉)，我想将其更新为最新版本(我发现

I have a Plone site (something around 4.2.4, telling from a version.txt in the root directory) which I'd like to update to a recent version (I found this how-to) (as of now, 4.3.4); I have inherited a plethora of pinned versions which are not documented and might be outdated.

注释掉我的versions.cfg时，改用http://dist.plone.org/release/4.3-latest/versions.cfg并用-vvv重新运行buildout时，我得到:

When commenting out my versions.cfg, using http://dist.plone.org/release/4.3-latest/versions.cfg instead and re-running buildout with -vvv, I get:

Develop: '.../src/collective.mathjax'
in: '.../src/collective.mathjax'
/tmp/tmpbXsnpD -q develop -mxN -d .../develop-eggs/tmp2yhe9ubuild
...
Installing 'zc.recipe.egg'.
We have the best distribution that satisfies 'zc.recipe.egg<2dev'.
Picked: zc.recipe.egg = 1.3.2
...
There is a version conflict.
We already have: zc.recipe.egg 1.3.2.
While:
  Installing.
  Getting section test.
  Initializing section test.
  Installing recipe zc.recipe.testrunner.

因此似乎对zc.recipe.egg的sub-2版本有一些要求，但我找不到它. (在我的versions.cfg中，它固定到了2.0.1-曾经可以正常工作).

So there seems to be some requirement for a sub-2 version of zc.recipe.egg, but I can't find it. (In my versions.cfg it is pinned to 2.0.1 - which used to work, surprisingly.)

我用find和grep搜索树，在version*.cfg和setup.py文件中寻找rc.recipe.egg，但是除了项目根目录外什么都找不到.我什至没有搜索.../src/collective.mathjax下的每个文件，都没有成功.

I searched the tree with find and grep, looking for rc.recipe.egg in version*.cfg and setup.py files, but I couldn't find anything but in my project root directory. I even searched every single file below .../src/collective.mathjax, without success.

如何找出这种依赖性?谢谢！

How can I ferret out this dependency? Thank you!

推荐答案

基本上，可以在三个地方查找版本固定:

Basically there's three places to look for version-pinnings:

1.)像Luca Fabbri指出的那样，在PyPi上释放的鸡蛋的需求文件，您可以搜索这样的图钉:

1.) The requires-files of eggs released on PyPi, like Luca Fabbri pointed out, which you can search for pins like this:

grep -r --include=requires.txt "dependency.to.search.for" path/to/eggs-cache

2.)开发鸡蛋的setup.py文件，类似的可搜索内容，例如:

2.) The setup.py-files of development-eggs, similar searchable like:

grep -r --include=setup.py "dependency.to.search.for" path/to/dev-eggs-cache

3.)配置文件的[versions]部分，在这种情况下， the version.cfg通过其extends -option和pull一个人可能还会通过extends指定更多配置.

3.) The [versions]-part of config-files, where in this case the version.cfg is pulling more version-configs in, via its extends-option and the pulled one's might also specify more configs via extends.

您很幸运，敬佩M. v.Rees共享了有关如何获取所有Plone版本的所有图钉的摘要: https://gist.github.com/mauritsvanrees/99cb4a25b622479e7dc3

You're lucky, admired M. v. Rees has shared a snippet, on how to get all pinnings of all Plone versions: https://gist.github.com/mauritsvanrees/99cb4a25b622479e7dc3
