我想使用pip-accel来加快对虚拟环境（例如 matplotlib、NumPy）的大量编译安装。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：

我是 pip-accel 的作者。我没有可用于测试的 Ubuntu 14.10 系统，并且在我测试过的 Ubuntu 12.04 和 14.04 系统上一切正常。但是，我可以为您提供一些有关如何解决此问题的提示。

根本原因分析

您包含的回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是否安装了 setuptools /usr/lib/python2.7（很可能是使用 apt 系统包安装的）
  • /usr/local/lib/python2.7/dist-packages/pkg_resources.py是否安装了 pkg_resources /usr/local/lib/python2.7（很可能使用sudo easy_install setuptoolsor安装sudo pip setuptools）

我很确定这解释了为什么 setuptools（一个提供多个模块的包）和 pkg_resources（一个由 setuptools 提供的模块）“不同步”。解决问题可能就像摆脱/usr/local/lib/python2.7/dist-packages/pkg_resources.py. 您可以尝试sudo pip uninstall setuptools，但请仔细检查以确保它只会触及其中的文件/usr/local（您不希望 pip 破坏使用 apt 系统包安装的 setuptools 的版本）。

pip-accel 0.22 不喜欢 pip 1.5.x

你提到：

我正在使用来自 Ubuntu 存储库的 pip（来自 /usr/lib/python2.7/dist-packages (python 2.7) 的 pip 1.5.6），但它似乎正在再次下载它（因为它不喜欢 1.5.x? )

这是正确的，pip-accel 0.22 需要比 1.5 更早的 pip 版本。今天我发布了使用更新版本的 pip 的 pip-accel 0.23（它需要 pip 6，如果 pip 不更改其版本控制方案以使次要数字成为主要数字，这就是 pip 1.6 的样子，但我离题了） .

pip-accel 和虚拟环境

您还提到：

如果有另一种使用 pip-accel 的方法（例如将其安装到目标 virtualenv 中），我会全力以赴，但看起来不像

这让我感到惊讶，因为 pip-accel 的主要用例（如其 README 中所述）是将其安装在您想要使用 pip-accel 安装 Python 包的 Python 虚拟环境中。所以这应该可以正常工作，请尝试一下！
