Question

我们正在使用Buildout作为在此处构建我们的软件包的方法，并且在尝试通过运行bin/buildout来下载鸡蛋时，我们总是会感到非常沮丧：

We have no distributions for python-dateutil that satisfies 'python-dateutil>=1.5'.
While:
  Installing python_section.
  Getting distribution for 'python-dateutil>=1.5'.

An internal error occured due to a bug in either zc.buildout or in a
recipe being used:

    data = self._sock.recv(self._rbufsize)
timeout: timed out

有没有办法防止这些超时？他们为什么会这样？

Answer 1

索引服务器无法响应，连接超时。例如，当PyPI关闭时会发生这种情况。默认情况下，索引服务器为http://pypi.python.org/simple，但您可以使用[buildout]选项index设置自己的索引服务器。

我们使用egg代理（使用collective.eggproxy设置）自动创建本地缓存，以避免此类问题。我们的扩建使用服务器作为索引，代理将从PyPI下载任何丢失的包并在本地缓存它们。因此，对于我们过去使用的任何软件包，即使PyPI（暂时）关闭，我们也可以继续提供服务。

使用Buildout时套接字超时
