如何在 Mac OS X 上为 Python 3 安装 pip？

How to install pip for Python 3 on Mac OS X?

提问by Travis Griggs

OS X (Mavericks) has Python 2.7 stock installed. But I do all my own personal Python stuff with 3.3. I just flushed my 3.3.2 install and installed the new 3.3.3. So I need to install pyserialagain. I can do it the way I've done it before, which is:

OS X (Mavericks) 安装了 Python 2.7 stock。但是我用 3.3 做所有我自己的个人 Python 东西。我刚刚刷新了我的 3.3.2 安装并安装了新的 3.3.3。所以我需要重新安装pyserial。我可以像以前那样做，即：

1. Download pyserial from pypi
2. untar pyserial.tgz
3. cd pyserial
4. python3 setup.py install

1. 从pypi下载pyserial
2. 解压pyserial.tgz
3. cd pyserial
4. python3 setup.py install

But I'd like to do like the cool kids do, and just do something like pip3 install pyserial. But it's not clear how I get to that point. And just that point. Not interested (unless I have to be) in virtualenv yet.

但我想像酷孩子一样做，只是做类似的事情pip3 install pyserial。但目前尚不清楚我是如何做到这一点的。而就在这一点上。对 virtualenv 不感兴趣（除非我必须）。

UPDATE: This is no longer necessary with Python3.4. It installs pip3 as part of the stock install.

更新：Python3.4 不再需要这样做。它安装 pip3 作为库存安装的一部分。

I ended up posting this same question on the python mailing list, and got the following answer:

我最终在 python 邮件列表上发布了同样的问题，并得到了以下答案：

# download and install setuptools
curl -O https://bootstrap.pypa.io/ez_setup.py
python3 ez_setup.py
# download and install pip
curl -O https://bootstrap.pypa.io/get-pip.py
python3 get-pip.py

Which solved my question perfectly. After adding the following for my own:

这完美地解决了我的问题。在为我自己添加以下内容后：

cd /usr/local/bin
ln -s ../../../Library/Frameworks/Python.framework/Versions/3.3/bin/pip pip

So that I could run pip directly, I was able to:

为了可以直接运行 pip，我能够：

# use pip to install
pip install pyserial

or:

或者：

# Don't want it?
pip uninstall pyserial

To use Python EasyInstall (which is what I think you're wanting to use), is super easy!

使用 Python EasyInstall（这是我认为您想要使用的），非常简单！

sudo easy_install pip

so then with pip to install Pyserial you would do:

所以然后用 pip 安装 Pyserial 你会这样做：

pip install pyserial

I had to go through this process myself and chose a different way that I think is better in the long run.

我必须自己经历这个过程，并选择了一种我认为从长远来看更好的不同方式。

I installed homebrew

我安装了自制软件

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

then:

然后：

brew doctor

The last step gives you some warnings and errors that you have to resolve. One of those will be to download and install the Mac OS X command-line tools.

最后一步为您提供了一些必须解决的警告和错误。其中之一是下载并安装Mac OS X 命令行工具。

then:

然后：

brew install python3

This gave me python3and pip3in my path.

这给了我python3并pip3在我的道路上。
