【问题描述】：

我尝试在我们的本地 pypi 服务器上安装 icalendar：

第一次尝试失败，现在我知道我需要对 pytz 使用 --pre。但是仍然找不到依赖项：

(pypi)pypi@gray:~> pip install --pre  -d packages  pytz
Downloading/unpacking pytz
  Downloading pytz-2013d.tar.bz2 (204kB): 204kB downloaded
Saved ./packages/pytz-2013d.tar.bz2
Running setup.py egg_info for package pytz

  warning: no files found matching '*.pot' under directory 'pytz'
  warning: no previously-included files found matching 'test_zdump.py'

现在我尝试安装 icalendar：

(pypi)pypi@gray:~> pip install -d packages icalendar
Downloading/unpacking icalendar
  File was already downloaded packages/icalendar-3.5.tar.gz
  Running setup.py egg_info for package icalendar

任何提示如何解决这个问题？

【问题讨论】：

您在安装icalendar 时是否尝试保留--pre？

是的，这解决了问题。请参阅我的答案的链接。

【参考方案1】：

见：Could not find a version that satisfies the requirement pytz

在旧版本中，pytz 的编号方案与 pip 不兼容。

这改变了。见https://bugs.launchpad.net/pytz/+bug/1224858
