Products.GenericSetup的Plone训练设置错误

Question

我正在努力学习如何为Plone 5开发一个副词。为了做到这一点，我坚持Plone 5培训(https://training.plone.org)。

按照培训的建议，我正在安装带有plone的Vagrant/Virtualbox机器，但当我尝试运行buildout时，总是会出现以下错误

vagrant@training:/vagrant/plonetheme.tango$ ./bin/buildout
Develop: '/vagrant/plonetheme.tango/.'
Updating _mr.developer.

/home/vagrant/buildout-cache/eggs/setuptools-20.7.0-py2.7.egg/pkg_resources/__init__.py:187: RuntimeWarning: You have iterated over the result of pkg_resources.parse_version. This is a legacy behavior which is inconsistent with the new version class introduced in setuptools 8.0. In most cases, conversion to a tuple is unnecessary. For comparison of versions, sort the Version instances directly. If you have another use case requiring the tuple, please file a bug with the setuptools project describing that need.

Error: The requirement ('Products.GenericSetup>=1.8.2') is not allowed by your [versions] constraint (1.8.0)`

我试图通过Products.GenericSetup更新easy_install，但是buildout似乎忽略了python文件夹中的更新版本。

Answer 1

在构建定义中的某个地方(我不知道Vagrant如何安装它，所以您必须查看.cfg文件中的内容)，您可能拥有：

[versions]
...
Products.Genericsetup=1.8.0

...while主题需要1.8.2版本。

只需添加以下内容：

[versions]
...
Products.Genericsetup=1.8.2
