我已经安装了 Python 3.3.2（x86 和 x64 版本）并在它们之上安装了 PyQt5.1。
最近我安装了 PyCharm 3.0 社区版并配置为使用这些 Python 解释器。问题是 PyQt5 未显示在已安装包的列表中，并且文档不起作用（Ctrl+Space自动完成和Ctrl+Q文档）。
当 PyCharm 查询骨架生成时，它似乎在处理 PyQt 但没有用。当我尝试使用 PyCharm 中的包系统安装 PyQt 时，出现以下错误：
C:\Program Files (x86)\PyCharm3.0\helpers\packaging_tool.py run on 10/06/13 13:58:52

错误：
pip.exceptions.DistributionNotFound: No distributions at all found for PyQt5
但这似乎是无关的问题。
PyQt5 使用二进制安装程序安装。系统是Win 7 x64。
更新：我发现以前索引中的日志无效，我试图让事情正常进行。该日志不包含有关 PyQt 的错误或警告。具体内容如下：
INFO - .skeletons.PySkeletonRefresher - Home path is C:\Program Files (x86)\PyCharm3.0

也许一些问题在于打包工具：
INFO - packaging.PyPackageManagerImpl - Running packaging tool: C:/Python/332_x64/python.exe C:\Program Files (x86)\PyCharm3.0\helpers\packaging_tool.py list
但是仍然没有报告错误。
