buildout中的版本范围.fg

我有一个项目想要维护Django 1.7的最新稳定版本（目前为1.7.1，但可能会更改）。buildout中的版本范围.fg

在setup.py，我指定的版本范围是这样的：

setup(
    # ... 
    install_requires = ['setuptools', 
     'django >= 1.7, < 1.8', 
    ], 
)

在buildout.cfg，我指定的相同：

[versions] 
django = >= 1.7, < 1.8 
ipython = >= 2.3.1, < 3.0.0

对于ipython，这个伟大的工程，但不幸的是Django似乎并不喜欢它：

Got Django 1.7.1. 
Uninstalling ipython_section. 
Installing python_section. 
While: 
    Installing python_section. 

An internal error occurred due to a bug in either zc.buildout or in a 
recipe being used: 
Traceback (most recent call last): 
    File "/usr/local/lib/python2.7/dist-packages/zc/buildout/buildout.py", line 1942, in main

    requirement = self._constrain(requirement) 
    File "/usr/local/lib/python2.7/dist-packages/zc/buildout/easy_install.py", line 603, in _constrain 
    requirement = _constrained_requirement(constraint, requirement) 
    File "/usr/local/lib/python2.7/dist-packages/zc/buildout/easy_install.py", line 1400, in _constrained_requirement 
    _constrained_requirement_constraint(constraint, requirement) 
    File "build/bdist.linux-x86_64/egg/pkg_resources.py", line 2786, in parse 
    reqs = list(parse_requirements(s)) 
    File "build/bdist.linux-x86_64/egg/pkg_resources.py", line 2714, in parse_requirements 
    "version spec") 
    File "build/bdist.linux-x86_64/egg/pkg_resources.py", line 2679, in scan_list 
    raise ValueError(msg, line, "at", line[p:]) 
ValueError: ('Expected version spec in', 'django[]>=1.7,,>=1.7,<1.8', 'at', ',>=1.7,<1.8')

为什么它失败了，我该如何解决它？

版本规范something = <= 1234无效。 =和<=都不是正确的语法。

我会以不同的方式处理问题。你使用你的setup.py的install_requires已经限制1.7到1.8之间的版本。构建将尊重该要求，所以您不需要在构建配置中复制它。

什么buildout版本固定是这样的：固定到一个特定版本。要么让增强选择它想要的，要么让它选择一个确切的版本。

我使用它的方式是将show-picked-versions = true选件添加到[buildout]零件。然后Buildout将打印出它所选择的版本列表。然后，我将该列表复制/粘贴到[versions]。这样你可以得到一个可重复的版本和一个不错的速度提升，因为buildout不必再次搜索这些版本的pypi。
