在 Mac 上安装 python 模块最兼容的方式是什么? [英] What is the most compatible way to install python modules on a Mac?

问题描述

我开始学习 python 并喜欢它.我主要在 Mac 和 Linux 上工作.当我使用 apt-get 安装 python 模块时，我发现在 Linux(主要是 Ubuntu 9.04)上它工作正常.我可以毫无问题地导入它.

I'm starting to learn python and loving it. I work on a Mac mainly as well as Linux. I'm finding that on Linux (Ubuntu 9.04 mostly) when I install a python module using apt-get it works fine. I can import it with no trouble.

在 Mac 上，我习惯于使用 Macports 来安装所有 Unixy 的东西.但是，我发现我安装的大多数 python 模块都没有被 python 看到.我花了一些时间玩 PATH 设置和使用 python_select .没有什么真正起作用，在这一点上我还没有真正理解，我只是在闲逛.

On the Mac, I'm used to using Macports to install all the Unixy stuff. However, I'm finding that most of the python modules I install with it are not being seen by python. I've spent some time playing around with PATH settings and using python_select . Nothing has really worked and at this point I'm not really understanding, instead I'm just poking around.

我的印象是 Macports 在管理 python 模块方面并不普遍.我想使用更被接受"(如果这是正确的话)的方法重新开始.

I get the impression that Macports isn't universally loved for managing python modules. I'd like to start fresh using a more "accepted" (if that's the right word) approach.

那么，我想知道，Mac python 开发人员使用什么方法来管理他们的模块?

额外问题:

你用的是苹果的python，还是其他版本?你是从源代码编译所有东西，还是有一个运行良好的包管理器(Fink?).

Do you use Apple's python, or some other version? Do you compile everything from source or is there a package manger that works well (Fink?).

推荐答案

最流行的管理 python 包的方法(如果你没有使用系统包管理器)是使用 setuptools 和 easy_install.它可能已经安装在您的系统上.像这样使用它:

The most popular way to manage python packages (if you're not using your system package manager) is to use setuptools and easy_install. It is probably already installed on your system. Use it like this:

easy_install django

easy_install 使用 Python 包索引，这对于 python 开发人员来说是一个了不起的资源.看看周围有哪些可用的软件包.

easy_install uses the Python Package Index which is an amazing resource for python developers. Have a look around to see what packages are available.

更好的选择是 pip，因为它试图 修复很多与easy_install相关的问题.Pip 使用与 easy_install 相同的软件包存储库，它只是工作得更好.真正需要使用 easy_install 的唯一时间是这个命令:

A better option is pip, which is gaining traction, as it attempts to fix a lot of the problems associated with easy_install. Pip uses the same package repository as easy_install, it just works better. Really the only time use need to use easy_install is for this command:

easy_install pip

之后，使用:

pip install django

在某些时候，您可能想了解一点 virtualenv.如果你在包需求冲突的项目上进行大量 python 开发，virtualenv 是天赐之物.它将允许您拥有各种包的完全不同版本，并根据您的需要在它们之间轻松切换.

At some point you will probably want to learn a bit about virtualenv. If you do a lot of python development on projects with conflicting package requirements, virtualenv is a godsend. It will allow you to have completely different versions of various packages, and switch between them easily depending your needs.

关于使用哪个 python，坚持使用 Apple 的 python 将不会让您头疼，但如果您需要更新的版本(我相信 Leopard 是 2.5.1)，我会选择 macports python 2.6.

Regarding which python to use, sticking with Apple's python will give you the least headaches, but If you need a newer version (Leopard is 2.5.1 I believe), I would go with the macports python 2.6.
