我想使用pip-accel来加速虚拟环境中的编译繁重的安装（例如matplotlib，NumPy）。它不在14.10 Ubuntu存储库中，所以我必须手动安装它。但是，我的安装尝试失败如下：

备注：
pip 1.5.6 from /usr/lib/python2.7/dist-packages (python 2.7)）中的pip，但它似乎又在下载它（因为它不喜欢1.5.x？）答案 0 :(得分：1)
我是pip-accel的作者。我没有可用于测试的Ubuntu 14.10系统，在我测试过的Ubuntu 12.04和14.04系统上，一切正常。但是，我可以为您提供有关如何解决此问题的一些提示。
您所包含的追溯中的路径名似乎暗示了此问题的根本原因：
/usr/lib/python2.7/dist-packages/setuptools是安装在/usr/lib/python2.7中的setuptools（很可能是使用apt系统软件包安装的）/usr/local/lib/python2.7/dist-packages/pkg_resources.py是/usr/local/lib/python2.7中安装的pkg_resources（很可能是使用sudo easy_install setuptools或sudo pip setuptools安装的）我很确定这解释了为什么setuptools（提供多个模块的软件包）和pkg_resources（setuptools提供的模块）“不同步”的原因。解决问题可能就像摆脱/usr/local/lib/python2.7/dist-packages/pkg_resources.py一样简单，但我无法告诉（没有更多上下文）该文件是如何到达那里的，以及删除它的最简洁方法是什么。您可以尝试sudo pip uninstall setuptools，但请仔细检查以确保它只会触及/usr/local中的文件（您不希望pip破坏使用apt系统软件包安装的setuptools版本）。
你提到了：
我正在使用来自Ubuntu repos的pip（来自/usr/lib/python2.7/dist-packages(python 2.7）的pip 1.5.6）但它似乎再次下载它（因为它不喜欢1.5） .X？）
这是正确的，pip-accel 0.22需要一个早于1.5的pip版本。今天我发布了pip-accel 0.23，它使用了更新版本的pip（它需要pip 6，如果pip不会改变它的版本方案以使次要数字成为主要数字，那将是pip 1.6，但我离题了）
您还提到了：
如果还有另一种方法可以使用pip-accel（例如将其安装到目标virtualenv中）我都是耳朵，但它似乎不是吗
这让我感到惊讶，因为pip-accel的主要用例（如其自述文件中所述）是将其安装在Python虚拟环境中，您希望使用pip-accel安装Python软件包。所以这应该工作正常，请尝试一下！
