Collecting bsddb3
  Downloading bsddb3-6.2.5.tar.gz (237kB) 100%
    Complete output from command python setup.py egg_info:

我已经为 windows 安装了 berkley db x86，并通过忽略 pip 缓存目录再次尝试安装。问题依然存在。

我做错了什么？

请帮忙。

@has 回答：

另一种方法是下载包文件，.whl 将其粘贴到 C:\python\Scripts 文件夹中。然后运行pip install {package_filename}.whl

我在这里为任何需要它们的人找到了 windows 二进制文件： http://www.lfd.uci.edu/~gohlke/pythonlibs
