如何在 Ubuntu 14.10 上安装 pip-accel？
How can I install pip-accel on Ubuntu 14.10?
我想使用 pip-accel 来加速虚拟环境（例如 matplotlib、NumPy）的编译密集型安装。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：
> pip install --user pip-accel

备注：
- 我正在使用来自 Ubuntu 存储库 (
pip 1.5.6 from /usr/lib/python2.7/dist-packages (python 2.7)) 的 pip，但它似乎正在再次下载它（因为它不喜欢 1.5.x？）
- 如果有另一种使用 pip-accel 的方法（例如，将其安装到目标 virtualenv 中）我洗耳恭听，但似乎不是这样
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。不过，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 pkg_resources 安装在 /usr/local/lib/python2.7 中（很可能使用 sudo easy_install setuptools 或 sudo pip setuptools 安装）
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）是 "out of sync"。解决这个问题可能就像摆脱 /usr/local/lib/python2.7/dist-packages/pkg_resources.py 一样简单，但是我无法告诉（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干净的方法是什么。您可以尝试 sudo pip uninstall setuptools，但请仔细检查以确保它只会接触 /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 的版本）。
pip-accel 0.22 不喜欢 pip 1。5.x
您提到：
I am using pip from the Ubuntu repos (pip 1.5.6 from /usr/lib/python2.7/dist-packages (python 2.7)) but it appears to be downloading it again (because it doesn't like 1.5.x?)
这是正确的，pip-accel 0.22 需要低于 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：
if there's another way to use pip-accel (e.g. install it into the target virtualenv) I'm all ears, but it doesn't seem like it
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 Python 虚拟环境中，您要使用 pip 安装 Python 软件包-加速。所以这应该可以正常工作，请尝试一下！
我想使用 pip-accel 来加速虚拟环境（例如 matplotlib、NumPy）的编译密集型安装。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：

备注：
- 我正在使用来自 Ubuntu 存储库 (
pip 1.5.6 from /usr/lib/python2.7/dist-packages (python 2.7)) 的 pip，但它似乎正在再次下载它（因为它不喜欢 1.5.x？） - 如果有另一种使用 pip-accel 的方法（例如，将其安装到目标 virtualenv 中）我洗耳恭听，但似乎不是这样
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。不过，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.pypkg_resources 安装在/usr/local/lib/python2.7中（很可能使用sudo easy_install setuptools或sudo pip setuptools安装）
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）是 "out of sync"。解决这个问题可能就像摆脱 /usr/local/lib/python2.7/dist-packages/pkg_resources.py 一样简单，但是我无法告诉（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干净的方法是什么。您可以尝试 sudo pip uninstall setuptools，但请仔细检查以确保它只会接触 /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 的版本）。
pip-accel 0.22 不喜欢 pip 1。5.x
您提到：
I am using pip from the Ubuntu repos (pip 1.5.6 from /usr/lib/python2.7/dist-packages (python 2.7)) but it appears to be downloading it again (because it doesn't like 1.5.x?)
这是正确的，pip-accel 0.22 需要低于 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：
if there's another way to use pip-accel (e.g. install it into the target virtualenv) I'm all ears, but it doesn't seem like it
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 Python 虚拟环境中，您要使用 pip 安装 Python 软件包-加速。所以这应该可以正常工作，请尝试一下！
