buildout MercurialRecipe 在多次导入时出错

Question

我一直在尝试导入几个包，这些包其实是我正在构建的一个蛋（egg）的依赖项。因为这些蛋不在奶酪商店（cheese store）上，所以我不能在我的 setup.py 脚本中使用 install_requires = ['pack1', 'pack2']。所以我试着用以下方式把它们添加到我的 buildout 配置中：

  1 [buildout]
  2 develop = .
  3 parts = 
  4     python
  5     pack1
  6     pack2
  7 
  8 extra_paths = ${pack1:location}/src/
  9     ${pack2:location}/src/
 10 
 11 [python]
 12 recipe = zc.recipe.egg
 13 eggs = myegg
 14 extra-paths = 
 15     ${buildout:extra_paths}
 16 
 17 interpreter = python
 18 
 19 [pack1]
 20 recipe = mercurialrecipe
 21 repository = https://repo.xxx.com/hg/pack1/
 22 
 23 [pack2]
 24 recipe = mercurialrecipe
 25 repository = https://repo.xxx.com/hg/pack2/

我可能这样做不太对——我刚开始接触 buildout。当我运行我的 bin/buildout 时，出现了以下错误：

Updating python.
Updating pack1.
pack1: Pulling repository https://repo.xxx.com/hg/pack1/ and updating /home/martin/proj1/parts/pack1
pulling from https://repo.xxx.com/hg/pack1/

Installing pack2.
pack2: Cloning repository https://repo.xxx.com/hg/pack2/ to /home/martin/proj1/parts/pack2
While:
  Installing pack2.

    An internal error occurred due to a bug in either zc.buildout or in a
    recipe being used:
    Traceback (most recent call last):
      File "/home/martin/proj1/eggs/zc.buildout-1.5.2-py2.6.egg/zc/buildout/buildout.py", line 1805, in main
        getattr(buildout, command)(args)
      File "/home/martin/proj1/eggs/zc.buildout-1.5.2-py2.6.egg/zc/buildout/buildout.py", line 584, in install
        installed_files = self[part]._call(recipe.install)
      File "/home/martin/proj1/eggs/zc.buildout-1.5.2-py2.6.egg/zc/buildout/buildout.py", line 1297, in _call
        return f()
      File "build/bdist.linux-x86_64/egg/mercurialrecipe/__init__.py", line 50, in install
        commands.clone(ui.ui(), get_repository(self.source), self.destination)
      File "build/bdist.linux-x86_64/egg/mercurialrecipe/__init__.py", line 18, in get_repository
        return hg.repository(ui.ui(), location)
      File "/usr/lib/python2.6/site-packages/mercurial-1.7.3-py2.6-linux-x86_64.egg/mercurial/hg.py", line 96, in repository
        repo = _lookup(path).instance(ui, path, create)
      File "/usr/lib/python2.6/site-packages/mercurial-1.7.3-py2.6-linux-x86_64.egg/mercurial/httprepo.py", line 203, in instance
        return statichttprepo.instance(ui, "static-" + path, create)
      File "/usr/lib/python2.6/site-packages/mercurial-1.7.3-py2.6-linux-x86_64.egg/mercurial/statichttprepo.py", line 146, in instance
        return statichttprepository(ui, path[7:])

如果我把 pack1 和 pack2 的顺序调换，那么 pack2 就会被安装。基本上它们两个都能正常工作，但一旦我尝试同时获取这两个包，就会出问题。

提前谢谢你们。
